When you think about staying healthy, what comes to mind first? Maybe eating more vegetables, hitting the gym, or getting better sleep. But here’s something that might surprise you: your oral health could be the key to unlocking wellness throughout your entire body.
This eye-opening topic was the focus of a recent Homes That Heal podcast episode featuring Dr. Eric Cornelius, a holistic dentist from San Antonio, Texas. Dr. Cornelius shared insights that challenge how we think about dental care and its impact on our overall wellness.
Most people see their mouth as separate from the rest of their body. We brush our teeth, floss (hopefully), and visit the dentist twice a year without thinking much about how oral health connects to our heart, kidneys, or immune system.
Dr. Cornelius explains that this way of thinking is completely backwards. “Your mouth isn’t just a standalone system,” he says. “It’s actually the main entry point to your bloodstream, immune system, and overall health.”
Every single day, bacteria from your mouth can enter your bloodstream. This happens when you eat, brush your teeth, or even just go about your normal activities. When your oral health is poor, harmful bacteria can travel throughout your body, potentially causing problems far from your mouth.
This means that skipping your daily oral care routine doesn’t just lead to cavities and bad breath. Poor oral health can contribute to serious health conditions like:
One of the biggest threats to both oral health and whole-body wellness is periodontal disease, also known as gum disease. Dr. Cornelius uses a simple analogy to help people understand this condition.
“Think of your gum tissue like a turtleneck sweater,” Dr. Cornelius explains. “It wraps around each tooth, creating a small space or pocket. When these pockets aren’t cleaned properly, they become the perfect hiding spot for harmful bacteria to grow and multiply.”
You know those numbers your dental hygienist calls out during your cleaning? Those aren’t random codes – they’re measuring how deep these pockets are around each tooth. Here’s what they mean:
The deeper these pockets become, the more room bacteria have to hide and cause damage. And here’s the scary part: these bacteria don’t stay in your mouth. They can enter your bloodstream and travel to other parts of your body, potentially causing inflammation and health problems elsewhere.
Dr. Cornelius doesn’t mince words when it comes to sugar, especially in the form of soda and sugary drinks. He calls soda “the perfect storm” for destroying teeth, and the science backs him up.
Here’s what happens when you drink soda:
But soda isn’t just bad because of the sugar; it’s also highly acidic on its own. This means it attacks your teeth in two ways: feeding harmful bacteria and directly eroding your enamel.
Dr. Cornelius shared a story from his dental mission work in Nicaragua. He encountered children who actually saw rotted front teeth as a status symbol because it meant their families could afford to buy soda. This heartbreaking example shows just how destructive these drinks can be.
If you want to protect your oral health and whole-body wellness, limiting sugary drinks is one of the most important steps you can take.
If you have older dental fillings, there’s a good chance they contain mercury. These “silver” amalgam fillings have been used since the Civil War, but we now know much more about the potential health risks of mercury exposure.
Mercury removal isn’t a routine procedure you want done by just any dentist. When it’s done the wrong way, both you and your dental team can be exposed to toxic mercury vapor.
That’s why the SMART (Safe Mercury Amalgam Removal Technique) protocol exists. It includes:
Dr. Cornelius shared a sobering statistic: “Dentists have five times more neurological toxicity than the general population. I don’t think that’s a coincidence.” This highlights why proper mercury handling is so critical.
If you have mercury fillings, you might be wondering whether you should have them removed. Dr. Cornelius suggests two approaches:
Either way, Dr. Cornelius emphasizes that this isn’t a decision to take lightly. You want to work with a dentist who is properly trained in safe mercury removal techniques.
Understanding the connection between oral health and whole-body wellness is just the first step. Here are some practical actions you can take:
Your oral health and whole-body wellness are more connected than you might think. Taking care of your mouth isn’t just about having a nice smile – it’s about protecting your overall health.
As Dr. Cornelius made clear, your mouth truly is the gateway to your body. By prioritizing oral health through proper daily care, regular professional cleanings, and working with knowledgeable dental professionals, you’re investing in your entire body’s wellness.
Whether you’re dealing with gum disease, considering mercury filling removal, or simply want to optimize your health, remember that small changes in your oral care routine can have big impacts on how you feel overall. Your mouth and your body will thank you for it.
