As a dental hygienist, I’ve seen how the oral microbiome affects our health. The mouth is full of microbes that keep us healthy. Recent studies have changed what we know about these microbes and their role in health.
This article will share the latest in this exciting field. We’ll look at how the oral microbiome can help us stay healthy.
Key Takeaways
- Over 65 years of research have taught us about the oral microbiome.
- There are over 774 known oral bacterial species, with one-third still unknown.
- New studies have given us fresh insights into the oral microbiome.
- Some bacteria, like Streptococcus mutans, can cause tooth decay.
- Other bacteria, like Streptococcus parasanguinis, can protect our mouths by changing nitrite.
The Intricate World of the Oral Microbiome
The mouth is full of life, hosting a wide variety of microbial habitats that make up the oral microbiome. Each part of the mouth, like the gums, tongue, teeth, and cheeks, has its own special microbial communities. Knowing how these microbes work together is key to keeping us healthy.
Understanding the Microbial Habitats Within the Mouth
Just like animals and insects live in different places, microbes in the oral microbiome live in various spots in the mouth. These spots can have very different types of microbes. Learning about these microbes and how they work together is important for staying healthy.
The Interplay Between Oral Microbes and Systemic Health
The oral microbiome affects more than just our mouths. It’s linked to many health issues, like diabetes, dementia, and heart disease. An unhealthy balance of microbes in our mouths can lead to these problems. But, a healthy balance can help protect us by fighting off bad germs and training our immune system.
“Our choices, from diet to oral care routines, directly impact the health of the oral microbiome and subsequently influence our overall health and wellbeing.”
Mapping the Oral Microbial Landscape
Exploring the oral microbiome is now more exciting than ever. Researchers have created new imaging methods to see how microbes live together in our mouths. They use color to show where different bacteria live and how they interact in dental plaque and on the tongue.
Studies have found that microbes form complex “microbial towns” in our mouths. Each layer has its own role. For example, a 2016 study by Mark Welch et al. showed us the detailed world of oral microbes.
Unveiling the Complex Organization of Oral Microbes
The oral microbiome is a complex place where many microbes live together. Recent research has shown how these microbes are organized and what they do. This knowledge helps us keep our microbiome healthy and fight off diseases.
- A 2012 study by Griffen et al. used 16S pyrosequencing to show the different bacteria in healthy mouths and those with periodontitis.
- Dabdoub et al.’s 2016 study found that even though oral microbes are different, they work together in periodontitis.
- Valm et al.’s 2011 research used special imaging to show how microbes are organized in our mouths.
Learning about the “microbial towns” in our mouths helps us make better ways to keep our microbiome healthy. This can prevent dental and other diseases.
Microbial Interactions: Friends or Foes?
The oral microbial towns are full of connections that can affect our health. Some microbes team up to cause disease, like Streptococcus mutans and Selenomonas sputigena. They work together to make acid that harms teeth. Understanding these partnerships is key to fighting disease and keeping our mouths healthy.
The Bacterial Dynamic Duo Driving Tooth Decay
Streptococcus mutans and Selenomonas sputigena are a bad team for our teeth. They create an environment that leads to cavities. Streptococcus mutans makes lactic acid, which Selenomonas sputigena uses to make more acid. This duo shows how important it is to know how microbes interact in our mouths.
Nitrite: A Prebiotic Ally for Oral Health
Nitrite, a byproduct of dietary nitrate, could be a prebiotic for good oral microbes. Studies show that Streptococcus parasanguinis uses nitrite to fight off harmful bacteria. Eating foods high in nitrate can help keep our mouths healthy by supporting good bacteria.
| Microbe | Role in Oral Health |
|---|---|
| Streptococcus mutans | Caries-causing bacterium that produces lactic acid, contributing to tooth decay |
| Selenomonas sputigena | Works in a symbiotic relationship with Streptococcus mutans, using the lactic acid as a food source and further enhancing acid production |
| Streptococcus parasanguinis | Beneficial bacterium that can use nitrite to produce antimicrobial molecules, suppressing the growth of tooth decay-causing pathogens |
“Unraveling these microbial partnerships is crucial for developing targeted strategies to disrupt disease-causing consortia and restore oral health.”
Unveiling the Oral Microbial “Dark Matter”
The human mouth is full of microbes, but a big part of them is still a mystery. These hidden microbes are called the “dark matter” of the oral microbiome. They belong to the Candidate Phyla Radiation (CPR) group and couldn’t be grown in labs before. But now, new ways to grow these microbes are helping us learn more about them.
Cultivating the Elusive CPR Bacteria
A big breakthrough was finding and growing the TM7x bacterium, a CPR group member. It was found to stick to another oral bacterium, Schaalia odontolytica. By finding a way to grow these microbes apart, scientists could study them more closely. This helped us understand TM7x’s role in the mouth.
Being able to grow and study these hard-to-find microbes has changed how we see their role in the mouth. By learning about their genes and how they act, researchers can now explore their effect on health and disease. This could lead to new ways to prevent oral health problems.
“Continued research of the oral microbiota using omics approaches is emphasized for improvements in human health and quality of life.”
As we keep learning more about the mouth’s microbes, the “dark matter” is becoming less mysterious. By studying these microbes, scientists can better understand how they affect our health. This could lead to new ways to keep our mouths healthy and prevent diseases.
Microbiome Findings in Oral Health
Oral Microbiome and Dental Caries
The oral microbiome is key to understanding dental caries, or tooth decay. Before, Streptococcus mutans was seen as the main cause. But now, we know there’s more to it. Bacteria like Selenomonas sputigena work with S. mutans to make acid that harms teeth.
Knowing how these bacteria work together is vital for fighting dental caries. Things like what we eat, smoking, and stress can change the balance in our mouths. This can lead to more harmful bacteria and fewer good ones.
- The mouth is home to over 700 types of bacteria, making it very diverse.
- Streptococcus mutans changed to live with our new diet full of sugar, becoming more common.
- Today, eating too much sugar, acidic drinks, and smoking hurts our mouth’s balance, causing diseases.
By studying how the oral microbiome and dental caries are linked, scientists can find new ways to keep our mouths healthy. This could help stop tooth decay before it starts.
“The oral microbiome is a critical component of overall health, and its dysbiosis can have far-reaching implications beyond just dental problems.”
The Oral Microbiome and Systemic Diseases
The oral microbiome is a complex group of microorganisms in our mouths. It plays a big role in our health. Research shows it’s linked to many diseases, like diabetes, dementia, heart disease, and oral cancer.
When the oral microbiome is out of balance, it can lead to diseases. Some oral microbes can make diabetes and gum disease worse. A study found a link between gum disease and diabetes, showing how our mouth and body health are connected.
But the oral microbiome can also protect us. Good microbes make compounds that help us stay healthy. Exercise can reduce inflammation in people with diabetes and gum disease, showing how our mouth can help our overall health.
Studying how the oral microbiome affects our health is important. New tech lets scientists look closely at our mouth’s microbes and their effects on us.
| Systemic Disease | Oral Microbiome Connection |
|---|---|
| Diabetes | Bidirectional association between periodontal disease and diabetes mellitus |
| Cardiovascular Disease | Periodontal pathogens considered risk factors for cardiovascular diseases |
| Rheumatoid Arthritis | Periodontal pathogens linked to increased risk of rheumatoid arthritis |
| Oral Cancer | Association between the oral microbiome and lymph node metastasis in oral squamous cell carcinoma |
As we learn more about the oral microbiome and health, we see big possibilities for new treatments. Keeping our oral microbiome balanced could protect us from many diseases. This could be a key to better health.
Biofilms: Microbial Cities in the Oral Cavity
In the mouth, microbes don’t live alone. They form complex communities called biofilms. Dental plaque on teeth is a great example of these microbial cities. It’s a thick layer of microbes, each with its own job.
The Role of Dental Plaque in Caries Development
These biofilms affect how teeth decay and get diseases. The 2017–2020 NHANES found over 1 in 5 adults in the U.S. had cavities. This shows how common this disease is.
Dental plaque leads to tooth decay. It forms through bacteria attaching to teeth, making a sticky matrix, and then sticking together. This process is key to plaque’s growth.
The mouth has the second most diverse microbes in the body, with most in biofilms. Knowing how these biofilms work is key to keeping teeth healthy. It helps prevent cavities and other mouth diseases.
| Key Findings | Prevalence |
|---|---|
| Untreated active caries in adults | 21.3% |
| Periodontitis in dentate adults | 42% |
| Bacteria existing in nature in biofilms | More than 95% |
| Microbial diversity in the oral cavity | Second most diverse |
Dental caries and gum diseases are common worldwide. They cost a lot for healthcare. Understanding oral biofilms is key to fighting these diseases.
Oral Microbiome Maturation and Early Childhood Caries
The study of how the oral microbiome and early childhood caries interact is fascinating. Research shows that how the oral microbes grow and change in the early years affects a child’s risk of severe tooth decay.
A study on 260 Swedish children from ages 2 to 5 has revealed important insights. It found 6,978 different types of microbes, with Streptococcus and Haemophilus being the most common. By age 5, the variety of microbes in the mouth had decreased.
This change in microbes was noticed from ages 2 to 3. By age 5, only four types of microbes were mostly found. These were Haemophilus, Bergeyella, Gemella, and Streptococcus.

These findings highlight the need to watch how the oral microbiome develops. Disruptions in this process can lead to early childhood caries. Diet, oral hygiene, and antibiotic use can affect the microbes in the mouth, raising the risk of severe dental disease in kids. By understanding the oral microbiome, researchers can create better ways to prevent oral health problems in young children.
The Immune System’s Interplay with the Oral Microbiome
The relationship between the oral microbiome and the immune system is key for good oral health. These two work together, with microbes helping train the immune system to fight off bad germs. The immune system keeps the microbes in balance.
When this balance is upset, like from too much inflammation, bad microbes can grow too much. This can lead to oral diseases. Researchers are studying how the immune system and oral microbiome interact. They hope to find new ways to treat oral health issues.
Studies have shown how the host-microbiome interactions and immune regulation work together. For example, Atarashi et al. (2017) found that oral bacteria in the gut can cause inflammation and affect the immune system. This shows how oral microbes can impact our overall health.
Franchi et al. (2012) also looked into how the immune system keeps the microbiome in check. They found that certain immune responses can tell good bacteria from bad, helping protect us from infection.
Research has linked changes in the oral microbiome to immune-related conditions like allergies and asthma. Cai et al. (2022) showed how oral bacteria can affect these conditions. This highlights the big impact of the relationship between the microbiome and immune system.
By understanding how the host-microbiome interactions and the immune system work together, researchers can find new ways to keep our mouths healthy. This could help treat many health issues.
Probiotics and Prebiotics for Oral Health
Keeping the oral microbiome healthy is key to avoiding dental problems like cavities and gum disease. Probiotics and prebiotics are now seen as a strong way to keep teeth and gums healthy. Probiotics are live good bacteria that help grow healthy bacteria in the mouth. Prebiotics, like dietary nitrite, feed these good microbes, making the mouth’s bacteria balance better.
Studies are looking into how probiotics and prebiotics can help with oral health issues. For example, a study found probiotics helped with inflammatory bowel disease. Another study looked at how probiotics affect pregnant women’s folate levels and could help with certain health problems.
Research also shows probiotics might help COVID-19 patients. A review of studies on probiotics and dairy in dentistry showed they could be very helpful.
The link between the oral microbiome and health is still being studied. But, it’s clear that probiotics and prebiotics could be big helpers in keeping our mouths and bodies healthy. Using these natural helpers could lead to new ways to improve dental and overall health.
“The oral microbiome is a complex and dynamic ecosystem that plays a crucial role in maintaining dental and overall health. Probiotics and prebiotics offer a promising approach to nurturing this delicate balance and promoting optimal oral wellness.”
