The foods we eat play an important role in our oral health. While some foods promote good tooth
health, such as leafy greens and cheese, others damage our enamel and can cause decay. Here are
some of the foods you should avoid in order to maintain a pristine smile:
Foods containing citrus can cause damage to your enamel and weaken the dentine inside your
teeth. The acidic make up of citrusy foods is what can thin your enamel and make it less strong.
When this happens, your teeth become more sensitive and discolored. You may know the usual
suspects like oranges, lemons, and grapefruits, but any tomato dish is likely to be acidic. Enamel-
weakening foods include pasta sauces and ketchup. Watch out for salad dressings, which often
have an acidic pH due to the vinegar content.
Although packed with nutrients, dried fruit also contains a hefty amount of sugar that can remain
on your teeth because of the sticky sweet insides of dried fruit. Of course, chewy candy takes this
to the next level and their sticky-like texture latches onto our teeth and builds up over time by
design. Sadly, childhood favorite peanut butter and jelly can all cause plaque buildup on teeth if
not monitored closely. The sticky peanut butter works to stick the sugary jelly to our teeth, where
the bacteria can cause harm.
Composed of refined carbohydrates, potato chips eventually break down into sugar. When the
sugar combines with bacteria, lactic acid is formed. Thus, potato chips can erode your teeth and
weaken your enamel. Popcorn also gets stuck in-between your teeth, breaking down into lactic
acid. Chewing a kernel can also crack your teeth if they’re weakened.
Steps to avoid tooth damage by food:
1. When eating foods with high acidity, try to eat foods that contain minerals such as calcium
and phosphorus to counteract it. Foods containing these minerals are whole grains, eggs,
2. Use fluoride-containing toothpaste twice a day, waiting 30 minutes after eating to brush
your teeth. You can also use a fluoride mouth rinse to help build your enamels strength
and prevent erosion.
3. Visit Premier Dental Associates for a checkup twice a year so that we can assess your
enamel and keep it strong.
4. Keep out acids by drinking water and chewing sugar free gum. This will keep your mouth
moist and help the flow of salvia, which neutralizes acids.
