What Impacts Our Oral Microbiome? 3m22s

• Understanding one's oral microbiome can help in various ways, particularly in relation to overall health 3m27s.
• The oral microbiome has an impact on everyone, as everyone has teeth and a mouth, and daily activities such as breathing, eating, drinking, and kissing affect it 3m40s.
• Every time a person swallows or breathes, the bacteria in their mouth can travel to other parts of the body and cause problems 3m55s.

2 Million Bacteria in Your Mouth 4m1s

• The oral microbiome is the second largest microbiome in the body, consisting of approximately 700 different bacteria that make up a total of 2 billion bacteria 4m3s.
• The oral microbiome is unique in that it contains various environments or niches within the same mouth, including areas under the gums, at the back of the throat, and on the teeth, each supporting different types of bacteria 4m16s.
• These environments within the oral microbiome can be hot, cold, wet, or dry, resulting in diverse populations of bacteria coexisting in the same mouth 4m29s.
• Daily habits such as kissing, breathing, and swallowing significantly impact the oral microbiome, with frequent kissing (more than 11 times a day) leading to the sharing of bacteria or microbiome with a partner 4m54s.
• Other factors, including air quality and personal habits, also influence the environment within the mouth and the types of bacteria that inhabit it 5m4s.

How Many People Have Oral Diseases? 5m14s

• The World Health Organization reports that 3.5 billion people globally have some sort of oral disease 5m25s.
• Approximately 10% of the world population, or 750 million people, suffer from severe gum disease, making it one of the most prevalent inflammatory conditions in the body 5m28s.
• There has been a growing interest in the oral microbiome over recent years, with people becoming more aware of its importance and seeking to understand and track their oral health 5m47s.
• The new generation is driving this shift, wanting to understand their health better and taking proactive steps to monitor and manage their well-being, including their oral health 6m13s.
• This increased awareness and interest in oral health have led to people seeking out testing and information on their oral microbiome, with some even traveling long distances to get tested and learn more about their oral health 6m6s.

Body Diseases Linked to Oral Microbiome 6m47s

• More than 90% of diseases can be traced back to an imbalanced microbiome, with the oral microbiome having connections to various body diseases, including infertility, heart disease, diabetes, Alzheimer's, rheumatoid arthritis, erectile dysfunction, and more 6m56s.
• Research has shown a strong connection and causation between the oral microbiome and general diseases, moving beyond correlation, and indicating that the relationship between gum disease and other conditions like heart disease is not just due to shared risk factors such as smoking 7m26s.
• Victoria Samson, a dentist with a focus on the oral microbiome, has six years of training in dentistry and has worked in the field, earning her the nickname "the Saliva Queen" 8m14s.

Steven Adjusting Chair? 8m33s

• The Institute is considered the best dental school in the world, focusing on the mouth-body connection and saliva testing, which inspired the idea of saliva tests in dentistry, similar to blood tests in medicine 8m34s.
• After becoming a dentist, working in both NHS and private practices, and later shifting to fully private, research was conducted during the COVID-19 pandemic, which led to the discovery that patients with poor oral health or gum disease were at a higher risk of COVID-19 complications 9m1s.
• A paper was written connecting oral health with COVID-19 complications, and further studies were conducted with universities and hospitals, using saliva samples to analyze the oral microbiome, as direct access to patients' teeth and gums was not possible due to COVID-19 9m23s.
• Research found that COVID-19 patients with gum disease were nine times more likely to have COVID-19 complications, highlighting the importance of saliva testing in dentistry 10m3s.
• The lack of commercial oral microbiome testing led to the development of one of the first oral microbiome tests in Europe, which was created a couple of years ago, and a new, improved test was recently developed 10m30s.

Research Linking COVID-19 and Oral Hygiene 10m46s

• A research paper titled "Could there be a link between oral hygiene and severity of COVID infections" was the first to link gum disease with worse COVID complications and became the most cited research paper by the British Dental Journal 10m48s.
• The paper was also picked up by the World Health Organization and SAGE, highlighting the importance of oral health for general health and leading to the reopening of dental practices 11m14s.
• A person with an unhealthy oral microbiome is nine times more likely to end up in ICU with COVID complications 11m33s.
• The link between gum disease and COVID complications is partly due to inflammation, as both conditions release inflammatory markers that can exacerbate each other 11m45s.
• Gum disease releases inflammatory markers from the mouth to the rest of the body, adding to the cytokine storm caused by COVID and making it worse 12m5s.
• Another factor is the presence of bacteria, as most COVID patients did not die from the virus itself but from complications, with bacterial infections being the number one complication 12m28s.
• Autopsies of COVID patients showed that oral bacteria from their mouth traveled to their lungs, causing bacterial superinfections that resulted in conditions like pneumonia, which was the actual cause of death for most patients 12m53s.

Can Your Oral Microbiome Kill You? 13m6s

• The oral microbiome can be fatal and potentially kill an individual 13m8s.
• Dentists were not adequately taught about the importance of bacteria in the mouth and its impact on the rest of the body 13m11s.
• The mouth's connection to the rest of the body was not fully understood, except for the risk of infective endocarditis after heart surgery 13m21s.
• After heart surgery, patients are often advised to avoid dental hygiene for about 6 months due to the high risk of infective endocarditis 13m31s.
• Infective endocarditis occurs when oral bacteria travel to a faulty heart valve, potentially causing death 13m41s.
• The connection between oral bacteria and other diseases or problems was not thoroughly explored 13m48s.

How Food Shapes Your Mouth 13m55s

• The shape of the mouth and jaw have changed due to the consumption of processed foods, which are designed to be easy to chew, resulting in an abnormal shape compared to how they were supposed to develop 14m20s.
• Western Price, a dentist, suspected that the high levels of tooth decay and crowding in industrialized areas were related to diet, and he traveled the world to compare the teeth of people in different regions 14m37s.
• Price found that twins who ate harder foods and had less sugar in non-industrialized areas had better jaw development, perfect teeth, and no decay, compared to their twins in industrialized areas 15m17s.
• The consumption of processed foods has led to a lack of hard foods in children's diets, resulting in underdeveloped jaws and muscles, which can cause crowding and tooth decay 15m39s.
• The size of teeth has not changed, but the lack of space for them to grow has led to crowding, and this can be seen in models of the jaw and teeth 15m53s.
• The prevalence of impacted wisdom teeth has increased in the last 30-40 years, likely due to changes in diet, and many children now require orthodontic treatment to straighten crowded teeth 16m28s.
• In contrast, cavemen did not have dentists, braces, or toothpaste, but they did not die from gum disease, decay, or crowded teeth, suggesting that the Western diet has contributed to these problems 16m45s.

What’s a Wisdom Tooth? 17m3s

• Wisdom teeth typically start coming in between 18 to 19 years old, but some people may experience their wisdom teeth erupting at a later age, such as 32 years old 17m3s.
• The name "wisdom teeth" is believed to come from the fact that they erupt when a person is older and supposedly wiser 17m48s.
• Teeth erupt at different times in a person's life, with baby teeth coming in up to the age of six or seven, and adult teeth stopping their eruption around 12 years old 17m22s.
• Wisdom teeth are unpredictable and can be impacted or cause problems, but some people may have wisdom teeth that erupt perfectly and are completely fine 18m12s.
• Not everyone develops wisdom teeth, and some people may have them come in at different times or not at all 18m2s.
• The eruption of wisdom teeth can be affected by various factors, resulting in some people experiencing problems with their wisdom teeth, while others do not 18m14s.

Do Wisdom Teeth Need Removal? 18m22s

• There is no clear evolutionary basis for the need for wisdom teeth, despite the expectation that there should be an evolutionary reason for their existence 18m22s.
• Research suggests that fewer people are developing wisdom teeth, possibly due to the increased removal of wisdom teeth in children and adults, which may lead to some individuals not having wisdom teeth at all over time 18m32s.
• As a result of this trend, some people may not have wisdom teeth because their ancestors did not have them, influencing their genetic makeup 18m45s.
• There is no real need for wisdom teeth, and having more teeth is generally considered better, as they can potentially be used for other dental purposes if needed 18m53s.
• It is generally preferred not to remove wisdom teeth unless necessary, as having more teeth can be beneficial in certain situations 18m56s.

Why Do We Need Dentists If Ancestors Had Good Teeth? 19m7s

• Ancestors from 500 years ago did not have dentists, toothpaste, or other oral hygiene products, yet they did not have tooth decay, suggesting that diet played a significant role in their oral health 19m9s.
• If an individual follows a "caveman diet" with no sugar or carbohydrates, they might not need toothpaste, floss, or a toothbrush, but this is only possible if they eat raw meat, drink only water, and avoid sugary or carbohydrate-rich foods 19m23s.
• Some people argue that toothpaste, floss, and other oral hygiene products are not necessary, but this approach is only suitable for those who maintain a diet with no sugar or carbohydrates 19m36s.
• The perfect diet can be inferred by looking at the mouth, as a diet with minimal sugar and carbohydrates is less likely to cause tooth decay 19m56s.
• Modern foods often contain high amounts of sugar, which affects the acidity of saliva and contributes to tooth decay 20m2s.
• Tooth decay occurs when bacteria in the mouth feed on sugar or carbohydrates, releasing acid that can cause demineralization and decay if left unchecked 20m11s.
• The demineralization process can lead to tooth decay, highlighting the importance of maintaining good oral hygiene and a balanced diet 20m27s.

Is Everyone’s Microbiome Massively Different? 20m33s

• Everyone's personal oral microbiome is massively different from one another, including differences between individuals in the same household or relationship 20m36s.
• Traditional oral microbiome testing methods only examine a limited number of bacteria, typically the top 20 that cause problems, which may not provide a complete picture of an individual's oral health 21m2s.
• The presence of certain bacteria alone does not determine oral health, but rather how the body responds to those bacteria and the specific strains present 21m21s.
• Different strains of the same bacteria can have varying levels of aggressiveness, with some causing significant problems and others being harmless 21m34s.
• A more comprehensive oral microbiome test can differentiate between patients with "bad" and "good" strains of bacteria, and also assess the ratio of good to bad bacteria, diversity, genetic mutations, and inflammation 21m43s.
• By considering these factors together, a more accurate understanding of an individual's oral health can be gained 22m4s.
• The uniqueness of an individual's oral microbiome, combined with their body's response to it, ultimately determines their susceptibility to oral health problems 22m14s.

How Oral Health Improves Overall Health 22m22s

• Even individuals who maintain good oral hygiene by brushing their teeth three times a day and eating well can still suffer from terrible gum disease due to genetic mutations that predispose them to gum disease and inflammation 22m32s.
• These genetic mutations can cause the body to respond aggressively and destructively to even small amounts of bacteria, leading to disease 22m50s.
• Unlike the gut microbiome, which turns over every couple of days or weeks due to peristalsis and movement, the oral microbiome can remain forever if not mechanically disrupted 23m21s.
• The teeth are the only non-shedding surfaces in the body, meaning that bacteria can continue to grow and form thick plaque if not removed through regular brushing or other means 23m40s.
• Regular mechanical removal of bacteria is necessary to maintain a healthy oral microbiome, which can be achieved through brushing teeth, using the correct toothpaste, or visiting a hygienist 24m11s.
• The oral microbiome's ability to persist indefinitely if not disrupted makes regular maintenance crucial to preventing disease 24m7s.

Can Swallowing Saliva Make You Sick? 24m22s

• There are two main ways oral health impacts overall health: the spread of bacteria and inflammation caused by oral health issues 24m25s.
• Swallowing saliva can potentially spread bacteria from the mouth to the rest of the body, which may cause problems 25m54s.
• A 7-year-old patient had a similar concern about swallowing saliva, believing it could spread "bad bugs" to the rest of his body, and as a result, he refused to swallow his saliva and instead dribbled or wiped it away 25m5s.
• The patient's concern was not entirely unfounded, as the mouth contains around 700 different bacteria and 2 billion bacteria overall, which can be swallowed and potentially travel to other parts of the body 25m46s.
• However, the acid in the stomach can kill many of the bacteria swallowed, and only the most resilient and problematic bacteria can survive and cause issues 26m0s.
• Maintaining a balanced oral microbiome is crucial to prevent the spread of harmful bacteria and minimize potential problems 26m12s.

Inflammation and the Oral Microbiome Link 26m16s

• Low-grade chronic inflammation in the oral microbiome can cause negative impacts on overall health through various mechanisms 26m17s.
• The oral microbiome is a delicate balance of good and bad bacteria, and an imbalance can lead to higher levels of bad bacteria and lower levels of good bacteria, causing inflammation 26m32s.
• Bad bacteria in the mouth can travel to other parts of the body and release inflammatory markers, contributing to inflammation elsewhere, such as in cases of rheumatoid arthritis 26m53s.
• Inflammation from the gums can exacerbate conditions like arthritis, making symptoms worse 27m12s.
• Low-grade chronic inflammation is often not noticeable, but bleeding gums can be a sign of underlying inflammation 27m25s.
• Bleeding gums are not normal and can indicate a problem, just like bleeding from other parts of the body would 27m32s.
• Inflammation in the gums can travel to other parts of the body and cause damage, with bleeding gums being a warning sign 27m46s.
• Bad bacteria in the mouth can also damage blood vessels by releasing toxic enzymes, affecting their ability to dilate and constrict 27m57s.

Rheumatoid Arthritis Strongly Linked to Oral Health 28m18s

• Research has shown that people with rheumatoid arthritis are eight times more likely to develop gum disease than patients without rheumatoid arthritis 28m21s.
• There is a strong bidirectional relationship between rheumatoid arthritis and gum disease, meaning that treating one condition can improve the other 28m34s.
• A patient with severe rheumatoid arthritis and gum disease was treated for gum disease, resulting in improved gum health and a significant reduction in rheumatoid arthritis symptoms, allowing her to stop taking steroids and medication and regain mobility 30m3s.
• The patient had previously seen multiple practitioners, but it was a spinal specialist who first suggested a connection between her teeth and rheumatoid arthritis, leading her to undergo saliva testing and gum disease treatment 29m25s.
• The saliva testing revealed high levels of inflammation, collagen breakdown, and bad bacteria, which were addressed through aggressive gum disease treatment 29m48s.
• The patient's case highlights the importance of the mouth-body connection and the potential for dentists to have a significant impact on systemic health 30m38s.

Heart Disease and the Oral Microbiome 30m43s

• Inflammation has an impact on cardiovascular functioning and health, with cardiovascular disease being a major killer worldwide 30m43s.
• Research has shown that individuals with gum disease have a 20% higher chance of high blood pressure, and up to 30-40% of cardiac issues in hospitals can be linked to oral bacteria causing problems in the heart valve 31m6s.
• The connection between oral microbiome and heart disease is partly due to inflammation and the release of toxic enzymes by bacteria that travel through the blood, causing blood vessels to constrict and dilate 31m30s.
• A study called "The Association Between Parodontitis and Blood Pressure" found that people with gum disease were twice as likely to have a heart attack and three times as likely to have a stroke than those without inflammatory gum disease 32m1s.
• Treating gum disease can significantly reduce levels of CRP, an inflammatory marker in the blood, which is often checked in patients with heart conditions 32m23s.
• Cardiac surgeons and doctors are now working with dentists to address the link between oral microbiome and heart health, as treating gum disease can lead to better results for patients 32m50s.
• The bacteria from gum disease can be swallowed and cause problems in the heart valve, particularly if it's faulty or has recently undergone surgery, making it prone to infection 33m7s.

How Oral Bacteria Filters Through Your Body 33m30s

• Oral bacteria can travel through the body on its own, regardless of whether it is swallowed or not, because they are living organisms that can find their way down through various means 33m35s.
• Oral bacteria can enter the body through the blood and the gums, in addition to being swallowed 33m40s.
• There are multiple pathways for oral bacteria to enter the body, including being swallowed, breathed in, or entering through the blood 33m45s.

Erectile Dysfunction Linked to Oral Hygiene 33m48s

• Research suggests that men with periodontal disease are 2.85 times more likely to suffer from erectile dysfunction, which is equivalent to a 280% increase in risk 34m10s.
• Periodontal disease, also known as gum disease, is a spectrum that starts with early stages of gum inflammation, which can progress to irreversible damage if left unchecked 34m26s.
• The early stages of periodontal disease are characterized by gum inflammation, which can be identified by bleeding gums when brushing teeth 34m30s.
• If left untreated, gum inflammation can progress to gum disease, where high levels of bad bacteria eat away at the gums and bone, leading to irreversible damage 34m49s.
• The link between gum disease and erectile dysfunction is due to the impact of gum disease on blood vessels, which can prevent them from dilating and reduce blood flow to the penis 35m30s.
• Reduced blood flow to the penis can lead to erectile dysfunction, making the connection between gum disease and erectile dysfunction a significant concern for men's health 35m38s.

Emerging Research: Breast Cancer and Oral Microbiome 35m56s

• Emerging research has found a link between oral health, specifically the oral microbiome, and cancer, including breast cancer and colorectal cancer 35m57s.
• The breast has its own microbiome, and research has shown that women with breast cancer have high levels of certain oral bacteria, such as Fusobacterium nucleatum, in their breast microbiome 36m36s.
• A comparison of breast microbiomes between healthy women and those with breast cancer found that women with breast cancer had very high levels of Fusobacterium nucleatum 37m12s.
• Research on colorectal cancer has also found that over 50% of patients had Fusobacterium nucleatum in their colons, and that oral bacteria can make cancer more aggressive and harder to treat 37m35s.
• A study in mice linked Fusobacterium nucleatum to tumor growth, and it has also been shown to accelerate tumor growth in colorectal and breast cancer 37m55s.
• While the research is new, it suggests that there may be a significant causal relationship between the health of the oral microbiome and the probability of developing certain forms of cancer 38m18s.
• However, it is believed that the relationship is multifactorial, and that oral health and specific oral bacteria are risk factors that can increase the aggression of cancers or even initiate them 38m27s.
• Research is ongoing, including a study on an antibiotic that only kills Fusobacterium nucleatum, which will be given to patients with colorectal cancer to see if it slows down their progression or improves their prognosis 38m57s.
• The causes of Fusobacterium nucleatum are believed to be multifaceted, including poor oral hygiene, genetics, diet, and lifestyle choices 39m38s.

Green Tea Benefits for Oral Health 39m53s

• Green tea has been found to be extremely effective at killing Fuso bacterium Nuclear, a type of bacteria, which is a significant discovery given its simplicity 40m6s.
• Testing for oral microbiome can reveal the presence of Fuso bacterium, and in one case, a person named Jack was found to have a high amount of this bacteria, which was described as "really badly out of control" 40m26s.
• Green tea has been given as a treatment to help combat the high levels of Fuso bacterium in Jack's oral microbiome 40m36s.
• Green tea has several benefits for oral health, including being anti-inflammatory, helping with oxidative stress, and having antibacterial properties 40m56s.
• The antibacterial properties of green tea make it effective at killing Fuso bacterium nucleatum, which is a significant advantage for oral health 41m6s.

Impact of Coffee on Oral Health 41m12s

• Coffee has no direct negative impact on the oral microbiome, but it can dry out the mouth, leading to reduced saliva production, which can cause problems for the oral microbiome 41m25s.
• Saliva plays a crucial role in the oral microbiome by providing food, proteins, and other essential nutrients to the bacteria in the mouth, acting as a delivery service that keeps the good bacteria alive and happy 41m35s.
• A dry mouth, which can be caused by excessive coffee consumption, nervousness, or certain medications like anti-depressants, can lead to a decrease in saliva production, causing the good bacteria to die and allowing bad bacteria to grow in their place 41m56s.

Effects of Hot Drinks & Sugar on Teeth 42m14s

• Drinking tea can dry the mouth, but not as severely as coffee, and may cause staining, but is generally not problematic unless excessive sugar is added 42m14s.
• Consuming high amounts of sugar in hot tea is particularly detrimental, as the sugar dissolves and the hot liquid can cause more problems than eating a sweet treat like a biscuit 42m28s.
• The way sugar is consumed is crucial, and having a large amount of sugar at once is preferable to sipping on a sugary drink over an extended period, as this allows the mouth to neutralize the saliva and recover more quickly 42m56s.
• Frequently sipping on sugary tea can cause the saliva to become acidic and stay that way, leading to tooth decay 43m19s.
• Drinks with artificial sweetness, such as Coca-Cola, are not as bad as those with natural sugars, but can still cause problems due to their acidity, which can lead to tooth erosion 43m41s.
• Tooth erosion occurs when the enamel layer of the tooth is worn away by frequent consumption of acidic drinks like fizzy sodas 43m55s.

Link Between Brain Health & Alzheimer’s 44m2s

• Certain oral bacteria, such as Porphyromonas gingivalis, can travel from the mouth to the brain and release toxic enzymes called gingipains, which can break down neurons and brain tissue 45m20s.
• A study found that 97% of Alzheimer's sufferers had these toxic enzymes in their brain fluid or tissue, compared to zero for patients without Alzheimer's 46m0s.
• Another study found that patients with Alzheimer's and gum disease experienced a more rapid cognitive decline than those without gum disease, highlighting the importance of maintaining oral health even after diagnosis 46m50s.
• The link between oral health and cognitive decline is still being researched, with attempts to separate the effects of gum disease from other potential causal factors such as poor diet and lifestyle choices 47m9s.
• Research has shown that there is a strong correlation between certain oral bacteria and Alzheimer's disease, with a specific oral bacteria, P. gingivalis, traveling to the brain and releasing enzymes that break down neurons, suggesting a causative link between the two 48m7s.
• A team working on Alzheimer's has identified oral health as one of the risk factors for the disease, alongside genetic mutations such as apo4, and has emphasized the importance of addressing oral health to reduce the risk of Alzheimer's 48m46s.
• P. gingivalis can be easily eliminated if detected through testing, and a specific test is available that can identify the presence of this bacteria in the mouth 49m21s.
• There is a correlation between poor mental health and poor oral health, but the causative connection between the two is not yet established, with research suggesting that a decline in mental health can lead to poor oral health, which can exacerbate issues 50m17s.
• Research has also explored the link between oral health and other mental health conditions, such as schizophrenia, but more evidence is needed to establish a clear connection 50m31s.
• A test is available that can identify the presence of certain oral bacteria, including P. gingivalis, and can provide information on the state of oral health 50m38s.

• Dentists may need to discreetly discuss these findings with the patient or their mother to address the issue 52m13s.

How Stress Affects Your Oral Health 52m18s

• There is a relationship between stress and oral health, where higher cortisol levels due to stress can negatively impact oral health, regardless of lifestyle choices 52m19s.
• Stress can increase inflammatory markers and inflammation, and also cause dry mouth, all of which can be linked to oral health issues 52m30s.
• A test for collagen breakdown, specifically the enzyme MMP-8, can be used to determine the level of collagen breakdown in the gums, which can be an indicator of gum disease 52m42s.
• High levels of collagen breakdown can be caused by intense stress, as seen in a patient who had recently experienced the loss of a baby, resulting in extremely high levels of collagen breakdown 53m30s.
• The impact of stress on oral health can be temporary, as the patient's collagen breakdown levels returned to normal after 6 months 53m46s.

Mouth vs. Nose Breathing: Health Impacts 53m54s

• Research suggests that changes in the shape of the mouth due to diet have led to various downstream health implications, including the way people breathe, with some individuals breathing through their mouths instead of their noses 53m55s.
• There is a link between mouth breathing and conditions such as ADHD, attention deficit, bedwetting, and teeth grinding, as observed by an orthodontist who treats children with these issues 54m55s.
• The orthodontist's approach involves helping children stop breathing with their mouths open, which can be relatively easy to treat due to the malleability of their jaws 54m51s.
• Adults who are mouth breathers often have difficulty changing their breathing habits due to their teeth not meeting correctly or their jaws being in the incorrect position 55m40s.
• Mouth breathing has been linked to various health issues, including long COVID, inflammatory conditions, chronic fatigue, and tiredness 56m3s.
• The nose acts as a filter system, with a specific temperature and mucus that helps catch bacteria, whereas the mouth has no filter, making it more likely for unhealthy oral microbiome to develop when breathing through the mouth 56m25s.
• Mouth taping has become a trend, which involves taping the mouth at nighttime to encourage nose breathing, and can be a useful way to test whether one breathes with their mouth open 56m56s.
• Mouth taping can help improve sleep quality, oxygen levels, and may encourage individuals to address the underlying reasons for their mouth breathing, such as straightening their teeth 57m12s.

Higher ADHD Risk in Mouth-Breathing Children 57m36s

• A six-year study of 11,000 children found that children who suffered from sleep disorder breathing were 50 to 90% more likely to develop ADHD-like symptoms than normal breathers who breathe through their nose correctly 57m42s.
• The increased risk of ADHD-like symptoms in mouth-breathing children is mainly due to the reduced delivery of oxygen to the brain, resulting in the brain not receiving enough rich, filtered oxygen to function properly 58m8s.
