8 Worst Foods for Your Oral Health

Dental Tips: 8 Worst Foods for Your Oral Health

Not everybody knows this, but the foods we eat are directly linked to our oral health. You probably already heard that sodas and sweets are bad for our teeth. But did you know that even some foods that are considered healthy can also be bad for them?

That’s right. And in today’s article, we will talk about the interesting dental tips of 8 foods that are really bad for your teeth.

Saltine Cracker

Saltine crackers, chips, bread and pasta are all fermentable carbs which are the sneaky super bad sugars. When you’re eating these types of foods chewing on them they start to get sticky and stuck all up in your teeth. Therefore, when food gets stuck into your teeth that makes matters even worse because it’s harder to clean out so when you’re craving starchy carbs like bread try to eat less refined varieties such as whole wheat.

They have fewer added sugars which help reduce your rate of getting cavities. Also, try not to let these carbs be stuck on your teeth for a prolonged period of time and make sure you are always drinking water while you’re eating them to help wash it away off your teeth.

Dried Fruit

Although they are considered to be a healthy snack, dried fruit tends to be very sticky, so they can damage your teeth by clinging onto the teeth crevices for longer periods of time, eventually leading to decay.

Just skip the dried fruit and eat the fresh fruit if you can and if you can’t because you’re on a road trip or something and dried fruit are just what you have make sure you properly brush and floss after so none of that sticky dried fruit is stuck all up in the crevices of your teeth. Also always drink water as well.


It’s no secret that soda is bad for your teeth because most soft drinks contain a massive amount of sugar but that’s not the only issue with soda.

Soda is very acidic as well so it’s not only the sugar, it’s the acidity that can break down your enamel and the sugar as we all know can give you cavities.

Citrus fruits

When consumed in excess, citrus fruits can be harmful. Because of their acidity, they can erode the teeth which harm the outermost layer of a tooth, causing irreversible wear and facilitating the presence of cavities.

If you really need to satisfy that citrus urge make sure to drink plenty of water afterwards to wash off any acids sticking onto the tooth surfaces.


Tea contains fluoride, and even though many consider it essential to oral health, if consumed in excess, tea can weaken our bones and teeth.

If you want to keep drinking tea, but don’t want it to harm your teeth, keep its consumption up to 4 cups per day, at maximum.


Although this is a sweet treat you can’t resist, candies contain a lot of sugar which is harmful to your teeth. Hard candies can even break or crack your teeth leading to a dental emergency.

Sour candies contain different types of acid which can weaken your enamel and chewy candy tend to stick to your teeth. As an alternative, I recommend sugarless gum or even chocolate because it’s a lot easier to wash off.

Remember that gummy vitamin are basically also candy and very unhealthy for your teeth too. They are packed with sugar and also sticky so if you can, choose vitamins that you can swallow or that are at least chewable so when you rinse with water after it won’t be all stuck up in your teeth.


Either white or red, wines are healthy if drank in moderation. Did you know that drinking too much red wine can stain your teeth? White wines can damage the enamel of your teeth because of their acidity, leaving your teeth sensitive or weak.

Alcohol dries out your mouth causing dehydration. This leads to tooth decay, oral infections and gum disease. Heavy consumption of alcohol can even increase the risk of oral cancer.


Although there are no sugar or carbs or acid or anything, ice is hard and oftentimes people chew on ice.

What can happen if you chew on ice is that it can cause unnecessary stress on your teeth which can crack your teeth causing long-term sensitivity and enamel loss which can increase the risk of dental emergencies. So, ice is fine to cool your drink but it is not fine to chew on.

Remember that you don’t need to completely cut these foods off your diet. Just consuming them moderately and taking the necessary care after meals will keep your teeth healthy, beautiful and white. For many people, a smile is like a business card, so we need to take care of our mouths: Brushing at least three times a day, flossing after meals and regularly visiting a dentist.
