7 Things Your Teeth Say About Your Health

When was the last time you visited the dentist? Are your teeth in impeccable condition?

According to a story on Care.com, some messages coming out of your mouth bypass the vocal chords. Turns out that your teeth, gums, and surrounding tissues also have plenty to say — about your overall health. This just means, dental problems aside, bad teeth could signal problems your body is facing.

“Your mouth is connected to the rest of your body,” says Anthony Iacopino, dean of the University of Manitoba Faculty of Dentistry and a spokesperson for the American Dental Association. “What we see in the mouth can have a significant effect on other organ systems and processes in the body. And the reverse is also true: Things that are going on systemically in the body can manifest in the mouth.”

Dental warning #1: Flat, worn teeth plus headache

Sign of: Big-time stress

Many people are surprised to learn they’re tooth-grinders. After all, they do this in their sleep, when they’re not aware of it. And they underestimate the physical toll that stress can place on the body. “Crunching and grinding the teeth at night during sleep is a common sign of emotional or psychological stress,” says Iacopino.

You can sometimes see the flatness on your own teeth, or feel it with the tongue. Or the jaw may ache from the clenching.

What else to look for: Headaches, which are caused by spasms in the muscles doing the grinding. Sometimes the pain can radiate from the mouth and head down to the neck and upper back, Iacopino says. Mouth guards used at night can relieve the symptoms and protect teeth

Dental warning #2: Cracking, crumbling teeth

Older adults, especially, are vulnerable to teeth that appear to be cracking or crumbling away. The enamel becomes thin and almost translucent. But this erosion isn’t a normal consequence of aging. In fact, it can happen at any age.

Disintegrating teeth are usually caused by acid that’s coming up from the stomach and dissolving them, Iacopino says. The cause: Gastroesophageal reflux disease (GERD, also called acid reflux disease). GERD causes stomach acid to back up into the esophagus — and from there, it’s a short distance to the mouth for some of the damaging acid. GERD is a chronic disorder caused by damage or other changes to the natural barrier between the stomach and the esophagus.

What else to look for: Dry mouth and heartburn are related GERD symptoms. (But in an older adult in someone else’s care — in a nursing home, for example — these complaints may go unreported.) Cracking or chipping teeth in a younger person is also a telltale sign of bulimia, the eating disorder in which the sufferer causes herself (or himself) to vomit before digesting. Same net result: Stomach acid washes up into the mouth, over time disintegrating the tooth enamel.

Dental warning #3: Gums growing over teeth

Sign of: Medication problems

If you notice your gum literally growing over your tooth, and you’re taking a medication for heart disease or seizures or you take drugs to suppress your immune system (such as before a transplant), it’s well worth mentioning this curious development to your prescribing doctor.

“A swelling of the gums to where it grows over the teeth is a sign the dosage or the medication need to be adjusted,” the ADA’s Anthony Iacopino says. Certain drugs can stimulate the growth of gum tissue. This can make it hard to brush and floss, inviting tooth decay and periodontal disease.

What else to look for: The overgrowth can cause an uncomfortable sensation. In extreme cases, the entire tooth can be covered.

Dental warning #4: Dry mouth

Sign of: Sjogren’s syndrome, diabetes

Many things can cause dry mouth, from dehydration and allergies to smoking and new medications. (In fact, hundreds of drugs list dry mouth as a side effect, including those to treat depression and incontinence, muscle relaxants, antianxiety agents, and antihistamines.) But a lack of sufficient saliva is also an early warning of two autoimmune diseases unrelated to medicine use: Sjogren’s syndrome and diabetes.

In Sjogren’s, the white blood cells of the body attack their moisture-producing glands, for unknown reasons. Four million Americans have Sjogren’s, 90 percent of them women. Twenty-four million people in the U.S. have type 1 or type 2 diabetes, a metabolic disease caused by high blood sugar.

What else to look for: Other signs of diabetes include excessive thirst, tingling in the hands and feet,frequent urination, blurred vision, and weight loss. In Sjogren’s, the eyes are dry as well as the mouth, but the entire body is affected by the disorder. Because its symptoms mimic other diseases (such as diabetes), people are often misdiagnosed and go several years before being properly diagnosed.\

Dental warning #5: Crusting dentures

Sign of: Potential aspiration pneumonia

Most people don’t connect dentures (false teeth) with pneumonia, other than to think they’re both words that often refer to the world of the elderly. And yet the two have a potentially deadly connection. “A leading cause of death in older people is aspiration pneumonia, often from inhaling debris around the teeth and dentures,” Iacopino says.

In aspiration pneumonia, foreign material is breathed into the lungs and airway, causing dangerous (even fatal) inflammation. Too often, the problem stems from people in the care of others — those in nursing homes, for example — who fail to clean dentures properly. Dentures need to be removed daily from the mouth, cleaned with a special brush, and stored in a cleansing solution.

What else to look for: A soft, crusty material developing around dentures. With proper cleaning, though, you don’t have to worry about other red flags. “It’s amazing. You can get a 100-percent reduction in what’s otherwise a leading cause of death for denture wearers,” Iacopino says.
