Oral Dysbiosis is Driving Disease, Popular Oral Care Products You Should Throw in the Trash, and How Your Diet Can Help Remineralize Your Teeth
Mon, 12 May 2025
This episode is brought to you by LMNT, Fatty15, and Levels. The oral microbiome is a foundational pillar of whole-body health and longevity. While modern science is just beginning to catch up, traditions like Ayurveda, along with Functional Medicine practitioners and biological dentists, have long emphasized the mouth-body connection. Without healthy teeth, gums, and oral tissues, systemic health inevitably declines. In this episode, today’s guests share how oral health offers a powerful lens into overall wellness—and why it’s time to rethink how we care for our mouths. Today on The Dhru Purohit Show, we’re bringing you a special compilation episode featuring Dhru’s conversations with leading experts on the connection between oral health, chronic disease, and longevity. Dr. Staci Whitman breaks down the top signs that your oral health may be at risk, explores the root causes behind common dental diagnoses, and explains the link between poor oral health and chronic illness. She also shares actionable tips on nutrition, optimal eating timelines, and strategies to prevent oral dysbiosis and cavities. Dr. Mark Burhenne dives into why prioritizing oral health is essential for preventing chronic disease and offers simple steps to get started. He also walks through the cost-benefit analysis of root canals and explains why flossing matters, along with his picks for the cleanest, most effective oral care products on the market. Dr. Staci Whitman is a leading authority in functional dentistry. With a unique blend of scientific expertise and compassionate care, she's dedicated to creating a cavity-free world. Dr Staci is a triple board-certified in pediatrics, integrative dentistry, and naturopathic dentistry. She is one of only five dentists in the world to have her Functional Medicine Certification from the Institute of Functional Medicine. Dr. Mark Burhenne is a functional dentist.

Chapter 1: What is the connection between oral health and overall health?
Yeah. So the oral systemic connection is very well documented in research and just more and more research is coming out as we are learning more about these specific pathogens and microbes and how they work together. Essentially, if your gums bleed, so I like to say if there's pink in the sink, if you spit out and there's blood, that's a sign that your gum health is compromised.
That now is a way for bacteria in your mouth, pathogens, or even commensals to get into your vascular system, your blood supply, your lymphatic system, and they just catch a free ride. And they end up in organ systems they shouldn't. They can end up in the heart. They can end up in the brain. They can affect fertility. And
They can end up in your joints and lead to arthritis and autoimmune diseases. And so it's really important to maintain gum integrity. This is a lot like leaky gut, right? So it's the same concept of leaky gut. There's leaky gums. So you really want, that's a barrier from the outside world into the inside world.
So these bacteria, not only do they end up where they shouldn't, but they do release toxins, endotoxins, lipopolysaccharides that can create an inflammatory response, a cytokine response, and it's being linked to cardiovascular disease, Alzheimer's, dementia, mental health imbalances. It can impact fertility, it can impact pregnancy outcomes, rheumatoid arthritis, autoimmune diseases.
You have to remember too, you're swallowing about 2000 times a day. And a lot of those bacteria are pretty resilient. They can actually withstand the stomach acid and get down into our intestines and kind of wreak havoc down there. So et cetera, et cetera. The root cause of all oral disease is dysbiosis. And what is that? That means imbalances in your oral microbiome.
We speak so much in the health and wellness world about the gut microbiome, but I think finally the oral microbiome is getting the attention it deserves. So what I look for as a practitioner are the usual suspects. Are you leaving with a diagnosis from your dentist? So do you have cavities, which is a sign of dysbiosis? Do you have gum disease? When you brush or floss, are your gums bleeding?
That's a sign of inflammation. Have you been diagnosed with periodontal disease? When you hear the hygienist reading out the little numbers as she probes around your teeth, are they getting larger? That's a sign of not only inflammation, but attachment loss of your teeth. dry mouth, tonsil stones, ulcers in the mouth. There's quite a few things.
So if you are in and out of your dental office, easy peasy, no diagnosis, you're probably doing well. But if you go in and every time you seem to have a new treatment plan, you need a new cavity filled, you need to come back for a deep cleaning. If you're suffering from dry mouth, tonsil stones, halitosis, these are all signs of dysbiosis or oral disease.
You know, as a functional dentist and someone who's looking at root causes that are contributing to these, what are some of the root causes when it comes to some of the words that you mentioned? So let's start off with one of the basics, plaque buildup.

Chapter 2: What are the root causes of oral dysbiosis and plaque buildup?
the appropriate amount of radiographic exams because that's how we can see in between the teeth and see the structures down in the root and around the bone. So yes, you can arrest and remineralize. So what's important to understand is our mouths all day long are in a constant state of either remineralization or demineralization. And this is normal. This is a normal process.
So anytime we put things into our mouth other than a more neutral pH water, we will have an acid effect. So there's something called the Stefan curve. And this basically just has to do with the alterations in pH in the mouth throughout the day. So every time the pH drops into an acidic state, we will lose some minerals from our teeth through the acid attack and pulling it out into our saliva.
However, if we're healthy, if we're balanced, if our saliva is optimal, and if we are not snacking, grazing, and eating these ultra processed foods all day, our saliva will naturally through the calcium and phosphorus ions in our saliva and appropriate enzymes, it will remineralize the teeth. So this happens all day.
Now the problem is when this state is in balance, when we are leaning more towards a demineralized state than a remineralized state. So we want to do things that help promote remineralization. That is through diet, that's through optimizing our salivary health, through hydration and minerals, and certainly how we breathe as well.
And so there are a lot of protocols and products and things that we can use to help boost remineralization for those of us who may tend to find ourselves in an imbalanced state. But I personally am utilizing a lot of these protocols in my office, and I'm avoiding a lot of treatment. fillings, root canals, extractions, and anesthesia visits in my pediatric patients.
And to me, that's hugely important, not only for the procedure, but the emotional experience, because so many adults have trauma and emotional health issues because of how dentists have treated and arguably over-treated their teeth in the pediatric years. So I think this is a really important conversation, especially in our pediatric population, and
where maybe we could be avoiding this over-treatment and creating these negative dental experiences for these kids.
So I know you work a lot with kids, but let's say you have an adult coming into your office or at some point in time that you've experienced and you see that they have gum recession and they keep on getting cavities and they keep on having plaque buildup that's there. From all those things, what can you tell us about their diet, either what they're eating or what they're not eating?
Yeah. I mean, it's hard to make generalizations, but I would do an in-depth nutritional assessment and analysis with them. But I would be curious if they are eating more processed foods. The important thing to understand is not just sugar. Flour is also a culprit. Even things, carbohydrates like rice and breads and pastas, crackers, chips, granola bars,

Chapter 3: Can cavities be naturally reversed and prevented?
it's important to know we are born essentially with a pretty neutral mouth. We get inoculated with pathogenic bacteria from usually a caregiver, mom, dad, a family member. So these are transmissible, these bacteria. So we get these bacteria from someone in our community. And these pathogens, you know, generally, if you're healthy, you're able to maintain a a balance of these bacteria.
But if we're feeding them, if we're overfeeding them, these ultra processed foods, these fermentable carbohydrates, you know, sugar, flour, and frequency of eating, they're going to thrive and they're going to bloom and blossom and kind of take over. So there will be an imbalance.
If you tend to eat more paleo or the Mediterranean diet, and I'm not advocating for any type of diet, but we do know if you tend to eat more Meats, fruits, vegetables, nuts and seeds, healthy oils, you are much less risk for dental disease. And so you're going to have a much more balanced microbiome.
So after nutrition, I do think airway and nutrition's kind of tied together or equal, I would say, but how we breathe really matters too. So when you breathe through your mouth, the pH drops, you're creating an acidic environment and creating this perfect balance you know, perfect world for these pathogens to develop. So nasal breathing really is optimal.
And I know you've had guests on speaking about the importance of airway before. If people are interested in this, the book Breath by James Nestor is a go-to to fully understand what I'm speaking of, but it is important for our microbial health to be breathing through our nose as well. And It helps with nitric oxide production.
It helps keep our saliva in balance so we don't get xerostomia or dry mouth. You know, mouth breathers tend to have more tonsil stones. They tend to have more halitosis or bad breath too. And then all the way down is hygiene. I think hygiene's last. I hear some of these influencers, they tend to be more extremists, like the carnivore diet, people say, I don't brush, I don't floss.
I don't advise that. But the point is, ancestrally, you know, we didn't have impeccable oral hygiene. And, you know, 10,000 years ago, we really didn't have a lot of cavities. You look at There wasn't a lot of decay.
There was some bone loss or periodontal disease, but that means these species of bacteria are newer in our more modern society and they're getting fed and multiplying and expanding and spreading faster. through our diet. We're really feeding them.
Would you say that it's the same thing for kids? Is that order the same thing? It doesn't matter whether it's for adults or kids, it's the same thing?

Chapter 4: How does diet influence oral health and the oral microbiome?
So you may need antimicrobials for a short duration of time and stronger medicinal therapies, even sometimes antibiotics. But I don't like strong antimicrobials like essential oils every day. So that's twice a day, every day is your routine. toothpaste or product. Um, so, so yeah, thanks for the shout out. We were really excited. We actually have a varnish, which is professional strength.
I mentioned that earlier. So we actually won an award on as best new product is the Celerant best in class hygiene award from the, um, RDH group, which is a hygienist group. Um, and it's, this is what I'm using with my patients to, to arrest and reverse cavities. And it's, it's pretty incredible what it's doing. And we have
comparative and clinical trials coming out soon too, that I'll be happy to share with everyone.
A couple of quick questions on hydroxyapatite. We wrote a newsletter long ago about this before you guys had launched your product, just talking about how I shared my own end of one experience, which was when I was feeling a lot of gum sensitivity because I started having some recession, which I learned from my biological functional dentist, Dr. Roshian here in LA. I love her.
She was telling me I had a lot of recession on my left teeth, in my lower left teeth. She was like, you're right dominant hand and you're just, you're brushing too hard. You need to switch to an electric toothbrush. And
and then also let's like you know get you off of like some other things as well and then i naturally came across like hydroxyapatite so i started using that and my anecdote that i had shared with my audience was i noticed my teeth sensitivity in my lower left area like if i drink coffee or cold things anything on extreme temperature when i started using hydroxyapatite like that went away pretty much completely
And I ran out and we went traveling. My wife and I were traveling for like a month or two and I didn't have the toothpaste available to me. It wasn't easy to get where we were at in Europe and stuff a couple of years ago. And I remember that gum sensitivity coming back and I was like, oh man, this is so weird. And I came back and I went back to use my toothpaste and it went away again.
And I was like, okay, I think there's like something definitely there for me. And I wrote about that experience. So how is it that hydroxyapatite helps with sensitivity that sometimes people feel with their teeth.
Yeah, that's actually a valid finding that's supported by research. And there's a lot of white papers on that too, with how it reduces sensitivity. That's actually one of the most amazing things about hydroxyapatite is that's what people will notice.

Chapter 5: What are the top factors impacting oral health in adults and children?
uh compounds inside of it don't feed the bad bacteria i think that they inhibit bacterial proliferation so they they inhibit it they inhibit the biofilm from forming essentially got it yeah so another video separate from xylitol that ryan made that i marked down as a question to ask you is that he said hey listen some nano hydroxyapatite you got to be careful where it's sourced from because there can be some heavy metals associated with this i
That's the first that I'd heard about this. Have you heard about this? And what's the skinny that our audience should know about it?
It's kind of the wild, wild west. And some manufacturing practices are substandard. And the FCCS in the EU, which is the Oversight Committee for Consumer Safety, they were looking at nano hydroxyapatite. They started... some studies about eight years ago to see, because they were noticing it was kind of blowing up in Europe. So they said, hey, is this safe in consumer products?
So they started researching, doing their own data, doing their own studies. And there was one nano in particular that they set aside because it was showing no concerns. It wasn't showing any concerns with penetrating epithelial linings or creating calcifications. And so that is now become the standard. And it has to do with particle size, shape, aspect ratio.
This gets real nerdy quickly, but also the quality of it to make sure it isn't rampant in heavy metals. And so unfortunately, there are some nano manufacturing facilities in other countries where people are sourcing their nano from where they have tested really high. So you just want to make sure you're asking your brand, where are they sourcing from?
And I personally would only use a brand that's sourcing from and using Nanoxim. It's N-A-N-O-X-I-M. And I'm happy to link, we can list all the brands that I know of in the show notes for your audience. Okay. We need the FDA to get involved, obviously. So we need some standardization here in the United States too.
So this is where you just want to follow brands that are using ethical and transparent practices.
A couple of things you mentioned that I just want to get a chance to tease out, right? Do you feel comfortable making any recommendations of where you want people at home? Again, check with your doctor and your practitioner. But where should they be shooting for when it comes to their vitamin D? Because you mentioned vitamin D, vitamin K2, very important for teeth health.
and our dental health overall. So where do you like to see those numbers or what have you heard, if you feel comfortable mentioning to our audience?

Chapter 6: How should one use baking soda and floss for optimal oral care?
Oh, it's a systemic infection directly from the tooth itself. It's a very difficult thing to do. It's very technique sensitive. And if it's not done properly or if it's done on a tooth, that shouldn't... be getting root canaled, it will fail and those bacteria will will change again. It's a it's like a biome and it will get into your bloodstream and it will take out some of your organs.
It will require that you take a series of very strong antibiotics that could lead to ulcerative colitis or gut issues. And so root canals do have a bad reputation. Unfortunately, it doesn't mean that a root canal cannot work. There's actually a dentist here in La that she's a specialist. She's an endodontist. That's a dentist that does just root canals.
And that would be my recommendation is that if you're looking at a root canal, get a second opinion, first of all. Because sometimes, you know, people jump to the gun. Obviously, a dentist wants to get you out of pain. Sometimes they do the wrong tooth. It's hard to know which tooth is causing the pain. The need for root canal is based on pulpitis.
We talked about it earlier, where the pulp inside the tooth is dying. It's inflamed. It goes through a phase of a lot of pain. Sometimes the pain will go away. Often it does because the tooth is dead, but the infection is still there. And a lot of patients and a lot of dentists will say, oh, everything's fine. You survive that infection. incident of pulpitis and the swelling went away.
Well, then it gets you a year later and all of a sudden you're traveling, you're in a foreign country and you've got a fever and you've got a severe infection in other parts of your body from that one tooth. So it's important to get, I would say, see an endodontist, get pulp tested, get the tooth pulp tested, get a 3D image of it with an x-ray. Don't rely on regular conventional dental x-rays.
Find out what the problem is. Make sure that you have the tooth checked for fracturing. A lot of people will fall off. uh you know the sidewalk or a horse or a trampoline and when they fall they may not the blow is not to the face but as they fall their teeth are clenched and then the the jarring motion is transmitted to the teeth one tooth will kind of spider fracture
The way to see that is to shine a very bright light through the tooth. It's a transillumination device, very easy, inexpensive. Every dentist should have one. If there are fractures, no root canal will save that tooth. You'll have to extract it. But if the hard structure of the tooth is sound, there's infected tissue in there.
If it's removed properly, if you use lasers, ozone, these are all the newer techniques that this dentist here in LA is using. but not all dentists are using. We use chemicals, we use just little files that have serrations in them. We're pulling out that dead tissue. That's not enough.
You're leaving infected tissue behind, and over time- Yeah, you really have to properly make sure that nothing is left in, because just so people understand, a tooth is dead or is dying. you need to basically remove it, including the roots. But you got to make sure that that sort of cavitation, that little hole, that there's nothing left.

Chapter 7: What is FYGG toothpaste and why is it recommended?
I really don't have anything to add other than you scrape your tongue, take interest in your mouth, smile, stay away from toxins, see the right dentist. I mean, all the things we talked about. There are things that you can do at home that are simple and easy. There are things that you can take out of your routine like mouthwash. Don't spend the money and time. It's just it can really...
make things a lot worse for you. I mean, high blood pressure, who wants that? And by the way, when your blood pressure goes up, guess what? Your gums start receding. The blood supply in that tissue is so fragile and so tiny. It's a microvasculature. It's a peripheral blood supply.
When the blood pressure goes up, those parts of the body with like kidneys, same thing, small blood supply, they necrose, they die. And when the gum tissue dies at the edge, it recedes. So there are a lot of ways that oral health can impact your life in general. Yeah.
The mouth is about so much more than just where digestion starts. And doubling down on your oral health is incredibly important for optimizing your health and longevity. In fact, it could play a huge role and the key to unlocking better health for decades to come. And the best part is that it doesn't have to be complicated.
With the right information, the right daily habits, there are so many simple tips and tools to support your oral health. If you like today's episode and want to go a little deeper, I go even deeper on these topics with my full-length conversations with Dr. Stacey Whitman and Dr. Mark Brehena. You can find those links to the episodes in the show notes below.
Please also consider sharing today's episode with a friend. Do you know a friend who's thinking about improving their oral health or has talked to you about how the connection of the oral health and oral microbiome relates to other diseases like Alzheimer's disease? Well, I bet they're going to geek out on today's episodes. As always, thank you for tuning in. Drew Perrault signing off.
I'll see you next week.
