They say you are what you eat. And in no better place can that be seen than in your teeth. That’s because many foods and beverages can cause plaque, which does serious damage your teeth. Plaque is a bacteria-filled sticky film that contributes to gum disease and tooth decay. After you eat a sugary snack or meal, the sugars cause the bacteria to release acids that attack tooth’s enamel. When the enamel breaks down, cavities can develop.

Cavities are the most common chronic disease faced by people aged six to 19 years old, according to the Centers for Disease Control and PreventionTrusted Source. They cause complications like pain, chewing problems, and tooth abscesses. And if you don’t brush or floss your teeth, your plaque will harden and turn into tartar. Tartar above the gums can lead to gingivitis, an early form of gum disease.

How can you prevent plaque from wreaking havoc on your mouth? Besides brushing your teeth at least twice a day and flossing and visiting a dentist regularly, try to avoid or limit the foods below.

1. Sour Candies

It’s not surprising that candy is bad for your mouth. But sour candy contains more and different kinds of acids that are tougher on your teeth. Plus, because they’re chewy, they stick to your teeth for a longer time, so they’re more likely to cause decay. If you’re craving sweets, grab a square of chocolate instead, which you can chew quickly and wash away easily.

2. Bread

Think twice as you walk down the supermarket bread aisle. When you chew bread, your saliva breaks down the starches into sugar. Now transformed into a gummy paste-like substance, the bread sticks to the crevices between teeth. And that can cause cavities. When you’re craving some carbs, aim for less-refined varieties like whole wheat. These contain less added sugars and aren’t as easily broken down.

3. Alcohol

We all know that drinking alcohol isn’t exactly healthy. But did you realize that when you drink, you dry out your mouth? A dry mouth lacks saliva, which we need to keep our teeth healthy. Saliva prevents food from sticking to your teeth and washes away food particles. It even helps repair early signs of tooth decay, gum disease, and other oral infections. To help keep your mouth hydrated, drink plenty of water and use fluoride rinses and oral hydration solutions.

4. Carbonated Drinks

We all know that little, if any, good comes from soda or pop, even if it’s got the word “diet” on the can. A recent studyTrusted Source even found that drinking large quantities of carbonated soda could be as damaging to your teeth as using methamphetamine and crack cocaine. Carbonated sodas enable plaque to produce more acid to attack tooth enamel. So if you sip soda all day, you’re essentially coating your teeth in acid. Plus it dries out your mouth, meaning you have less saliva. And last but not least, dark-colored sodas can discolor or stain your teeth. A note: don’t brush your teeth immediately after drinking a soda; this could actually hasten decay.

5. Ice

All it contains is water, so it’s fine to chew ice, right? Not so, according to the American Dental Association. Chewing on a hard substance can damage enamel and make you susceptible to dental emergencies such as chipped, cracked, or broken teeth, or loosened crowns. You can use your ice to chill beverages, but don’t chew on it. To resist the urge, opt for chilled water or drinks without ice.
