8 Foods that are bad for your teeth

Avoid these foods that are bad for your teeth to keep your teeth in the healthiest condition.

8 Foods that are bad for your teeth: 

Corn on the Cob

Corn on the cob, while delicious and perfect for every bar-b-que, is a food that is bad for your teeth. The slippery outside skin of the corn kernels commonly get stuck in between teeth and either go undetected, or become impossible to get out. This leads to bacteria building up between the teeth, a common place for cavities. Also, corn is a vegetable that has a lot of sugar so it won’t help your waist-line much either.

Pop/Soda – even diet

Soda and Diet Soda are chocked full of acid, a big teeth corroding no-no. And although Diet Soda has no sugar, it is just as effective at corroding the enamel on your teeth. Not to mention how easy stains form after drinking soda. Many people sip on soda all day and the teeth are constantly sitting in acid-eroding fluids. If you must drink a soda, sip it through a straw and limit the amount of time spent drinking it through out the day. Avoid being an all-day-sipper and rinse with water after.


Apples and carrots are great for your body, but can be foods that are bad for your teeth because they are so hard. Apples and carrots are a big reason for broke or chipped teeth. You don’t have to remove these vitamin rich foods from your diet, simply cut them into bite-sized chunks for easier chewing.

Acidic Foods

It’s no secret that acidic fruits like limes, lemons, oranges, and grapefruits are already foods that are bad for your teeth. But what about other types of acidic foods? Other acidic foods can include: breads, cereals, pastas, wheat, rye, popcorn, rice, and different kinds of meat. Acidic foods are bad for teeth because the acid in the food breaks down the teeth’s protective layer of enamel, causing the teeth to be more susceptible to cavities.

Hard Candy

On top of being almost pure sugar, hard candies lead to broken teeth. Like with soda, people who eat hard candy typically do so throughout the day without giving the mouth a break to wash away all the sugar. And, let’s be honest, no one just sucks on the candy. There becomes a point when you start chewing on the candy to get it to break. Right? Avoid broken teeth by not chewing on hard candy and rinsing with water, or more preferably brushing your teeth, when you are done.


Lemonades and Limeades are summer’s #1 drink, but they are horrible for your teeth. Acid + sugar + sipping all day = Eroding enamel. Try watering down the lemonade to reduce it’s corrosive character. Or try this delicious 10-minute, 3-ingredient lemonade recipe. 


Vinegar is in a variety of tasty foods including pickles (or anything pickled for that matter), salad dressings, and marinades. Approach with caution though. According to Prevention.com a recent study showed that teens who ate vinegar-ladened foods saw an increase in tooth decay of 35-85%. What do you do if you love vinaigrette dressings? Continue to enjoy them! Studies suggest that lettuce combats the vinegar. Eat away.

Canned Fruits

Canned fruits are foods that are bad for your teeth because companies typically pack the juice with sugar. And if you are eating a citrus fruit that has been canned it’s a double whammy (we’re looking at you, you delicious mandarin orange). Stick to the fresh or frozen varieties of fruits for the nutrition without the added sugar.
