Packed with catechins (plant compounds with antioxidant properties) as well as naturally occurring fluoride, green tea appears to inhibit the bacteria and acid responsible for tooth decay, according to a review in the journal Pharmacognosy Review. The study looked at preliminary data, so more research is needed before suggesting the right dose, but the researchers still recommend sipping unsweetened green tea.

Danish researchers discovered that each daily 3.4-oz. serving of milk drops periodontitis rates by 4 percent. Calcium maintains your teeth's structure, and the "good" bacteria in yogurt may suppress "bad" bacteria that can lead to tooth loss. Bonus: Most milk is fortified with vitamin D (125 IU per cup).

Why Taking Care of Your Teeth Is Important for Your Health

Nine out of 10 dentists say that dental and medical docs should practice collaboratively because oral health problems can be linked with other conditions.

Heart Health

Patients with periodontitis have a greater risk of plaque blockages in their arteries, according to a review by U.K. researchers. "When bacteria accumulate around the gums, they cause tiny holes in the gum lining, allowing bacteria to enter the bloodstream and cause damage around the body," says study co-author Praveen Sharma.

Diabetes

Gum inflammation may be a sign of impaired blood sugar function. A Duke University study found that people with diabetes suffered about twice the tooth loss as those without the disease.

Acid Reflux

Finally, periodontitis can stem from acid reflux because sufferers often don't have enough saliva, leaving teeth vulnerable to bacteria and acid. Having reflux almost triples your risk of this condition, and also raises the odds of cavities by 150 percent, reported research in the journal Gut & Liver.
