Worst Foods For Teeth

Smiling Lips


NEW YORK – By now, we all know the basic recipe for healthy pearly whites, including regular brushing and flossing, and a diet rich in teeth-healthy foods. What we might notrealize is how some food choices can contribute to the wear and tear of teeth.

So what makes a food bad for your smile? That bacteria living in the mouth burn sugars in order to live. The byproduct of this burning is acid — which dissolves tooth enamel and causes cavities.

It’s important to note that some of the foods listed below aren’t necessarily bad forhealth — such as dried fruits — but the experts encourage teeth brushing or mouth rinsing after consumption to help prevent decay.

Dried Fruits
While dried fruits may be a definite step up from processed fruit snacks, they are still sticky and high in sugar. That means they not only adhere to teeth easily, but the sugar feeds the bacteria in the mouth, which can promote dental erosion, notes Joy Dubost, Ph.D., R.D., a spokesperson for the American Academy of Nutrition and Dietetics.

“I’m not saying don’t eat them, but just brush your teeth afterward,” Dubost says.

Messina adds that regular fresh fruits don’t typically have this problem because — even though they still have sugar — chewing them up promotes saliva and they don’t stick to the teeth.

“Fruits are generally pretty safe because they’re good for overall health and they’re chewy, so your average fruit has some substance to it and we chew through it, causing us to salivate more,” Messina says. “Saliva is a good thing because it has washing action and it’s a nautral buffer [to] acid.”

Sugary Drinks
Sugary drinks, such as sodas and sports drinks, are especially bad for teeth when sipping for long periods of time.

“If I have a soft drink or sports drink and I’m sipping it every 20 minutes, my teeth are getting bathed with a constant layer of acid,” Messina says. “So sitting down and drinking it all at once, or with a meal, is better than snacking or sipping throughout a meal.”

For this reason, Dubost recommends that parents don’t fill their kids’ sippy cups with sugary drinks, since kids, whose teeth are still developing, tend to sip at those drinks over long periods of time.

Hard Candies
For the same reason sipping on sodas all day is bad for teeth, hard candies aren’t ideal for oral health, Dubost notes. These sweets pack a double whammy in that they not only stick to the teeth, but they also linger in the mouth for a long time as you wait for them to dissolve.
Citrus/Acidic Foods
Foods high in acid, such as citrus or tomatoes, can promote tooth decay, especially when eaten alone, Dubost notes. But these foods are fine to eat so long as you flush your mouth with water after consuming them in order to buffer the acid.

Citrus not only has acid, but also sugar — and people who have a habit of sucking on lemons or limes are actually harmfully bathing their teeth in acid, Messina says.

“If you look in their mouths, their teeth have a shiny, glossy surface — that’s from constant bathing with the acids,” he says. “They will have almost a peculiar look in that you’ll see it on the front surfaces of their teeth, but not the back sides of the lower front teeth because those are under the tongue — and the tongue protects the surface of teeth.”

Starchy Foods
Starchy foods, such as potato chips and white bread, easily get trapped in teeth, which can then feed the bacteria that make up plaque, according to the Yale Medical Group.
Not only do drinks like coffee and tea stain the teeth, they also make the teeth stickier — meaning more food particles can latch on, Messina says.
