The Top 10 Sources of Chronic Inflammation Hiding in Your Mouth

Learn more about the 10 hidden oral triggers of inflammation

By Dr. Gerry Curatola, DDS DEC 2025

Most people think of their mouth as separate from the rest of their body. But in reality, the mouth is the front door to overall health. Bacteria, toxins, and chronic irritation that start in the mouth don’t stay there—they travel through the bloodstream, sparking low-grade inflammation that can silently damage the heart, brain, joints, and other organs. Scientists now agree that chronic inflammation is one of the biggest drivers of disease worldwide, and your mouth is often where it begins.

Here are the top 10 hidden sources of inflammation and toxicity in the mouth—and what you can do about them.

1) Gum Disease (Periodontal Disease)

Gum disease affects more than 8 in 10 adults at some point, making it one of the most common chronic infections in humans. The gums are like the skin around your teeth—when they are inflamed, they release toxins and inflammatory chemicals into the bloodstream day after day.Over time, gum disease has been linked to heart disease, diabetes, pregnancy complications, Alzheimer’s, stroke, and even some cancers. It’s often painless in the early stages, which is why it’s called a 'silent epidemic.'What you can do: Look for warning signs like bleeding when brushing, puffy gums, or bad breath. Regular cleanings, proper brushing and flossing, and microbiome-friendly toothpastes can help control it before it spreads.

2) Jaw Cavitations

Sometimes when a tooth is pulled—especially wisdom teeth—the bone doesn’t heal fully. These hidden pockets of dead bone, called cavitations, don’t usually show up on regular dental X-rays but can be seen with advanced 3D scans.Why does this matter? Cavitations can act like little 'toxin factories,' harboring bacteria, fungi, parasites, and even heavy metals. People with cavitations may struggle with fatigue, facial pain, or unexplained health issues without knowing the root cause.What you can do: If you’ve had teeth removed and experience chronic symptoms with no clear explanation, ask about a 3D cone-beam scan. A biological dentist can evaluate and treat cavitations safely.

3) Amalgam (Mercury) Fillings

For decades, 'silver' fillings were the standard in dentistry. But these are actually about 50% mercury. Each time you chew or drink something hot, tiny amounts of mercury vapor are released. Mercury is one of the most toxic metals on Earth—it can affect the brain, immune system, kidneys, and heart.Many people carry these fillings for years, unaware they are a constant source of exposure. Safer, non-toxic alternatives are now available.What you can do: Don’t rush to get those old fillings drilled out without protective protocols— or that can release more mercury. Instead, work with a biologic dentist trained in safe removal methods if you’re considering replacement.

4) Metal Crowns and Appliances

Crowns, partial dentures, retainers, and orthodontic wires are often made with metal alloys that include nickel, cadmium, or even lead. In the moist, acidic environment of the mouth, these metals can corrode, releasing ions into the body. For some, this triggers allergic reactions, hormonal imbalance, or chronic inflammation.What you can do: If you suspect sensitivity to metal dental work, testing for metal allergies is available. Biologic dentists can recommend ceramic, zirconia, or other biocompatible alternatives.

5) Titanium Implants

Titanium implants are popular for replacing missing teeth, but they are not completely 'inert.' Over time, they can shed microscopic particles, irritate nearby tissues, and attract bacterial biofilms. This can lead to peri-implantitis—inflammation around the implant site. For people with genetic or immune sensitivity, this adds another burden to the body’s inflammatory load.What you can do: If you need an implant, ask about zirconia implants, which may be less inflammatory. If you already have implants, regular monitoring of gum health around them is essential.

6) Root Canals

Root canals are one of the most debated treatments in dentistry. Once a tooth is root-canal treated, it’s essentially a 'dead tooth' left in place. Bacteria can survive deep in microscopic tubules of the tooth, producing toxins that the immune system constantly battles.These toxins can spread beyond the tooth, potentially contributing to autoimmune conditions, chronic fatigue, or even jawbone cavitations around the root.What you can do: If you’ve had root canals and suffer unexplained health issues, talk to a biologic dentist about evaluation. In some cases, removal and safe restoration may be recommended.

7) BPA-Containing Composites

White fillings may look safer than silver ones, but many contain bisphenol A (BPA) derivatives. BPA acts like estrogen in the body, interfering with hormonal balance. Studies link BPA to thyroid problems, reproductive issues, and cancers, and in children, to hyperactivity and behavioral concerns.What you can do: Ask your dentist if they use BPA-free composites. More options are available today that avoid these hormone-disrupting chemicals.

8) Obstructive Sleep Apnea (OSA) / Airway Disease

Sleep apnea affects over 1 billion people worldwide. When the airway collapses at night, oxygen levels drop, and the body is jolted into stress mode repeatedly. This sparks inflammation, raises blood pressure, and increases risk for heart disease, diabetes, and memory loss.Dental issues like a narrow palate, small jaw, or tongue-tie often contribute to OSA.What you can do: If you snore, wake up tired, or gasp for air at night, ask about a sleep study. Dental airway treatments can often correct the problem—sometimes without surgery.

9) TMJ Dysfunction (Jaw & Bite Problems)

The temporomandibular joint (TMJ) is the most sensitive joint in the body. When the bite is off, the joint and surrounding muscles are under constant strain. This can lead to headaches, neck and shoulder pain, jaw clicking, ear ringing, or difficulty chewing.Chronic inflammation in the TMJ doesn’t just cause pain—it can also disrupt the nervous system, sleep, and quality of life.What you can do: If you suspect TMJ issues, a dentist trained in bite alignment can help. Physical therapy, bite guards, or realignment can make a big difference.

10) Harmful Oral Care Products

Most toothpastes on store shelves today are based on detergent formulas invented over 100 years ago. They often contain fluoride, triclosan, artificial sweeteners, dyes, and sodium lauryl sulfate (SLS). These can irritate tissues, disrupt the oral microbiome, and even burden the immune system. Even many 'natural' pastes rely on strong essential oils that wipe out good bacteria along with the bad.A new approach to oral care is prebiotic oral care, which nourishes the good bacteria instead of sterilizing the mouth. This helps protect teeth, strengthen gums, and reduce inflammation naturally.What you can do: Look for a toothpaste designed to support the microbiome. One example is Revitin®, formulated with vitamins, minerals, and botanicals in a safe, swallowable base.

After more than 40 years of clinical experience, I’ve seen that when patients remove hidden sources of inflammation from the mouth, their overall health often transforms. Energy improves, chronic conditions calm down, and the body begins to heal.Your mouth is not separate from your body—it’s the gateway to total wellness. By addressing these 10 hidden sources, you’re not just protecting your smile. You’re protecting your heart, brain, immune system, and future health.
