Our diet not only affects our fitness level but our oral health as well. You will be surprised to know how a certain type of food can severely deteriorate the condition of your teeth.

Our oral health is directly linked to our overall wellbeing. Tooth decay can occur at any age if oral hygiene is not maintained properly. When we consume foods that are bad for our teeth, plaque and cavities are formed which results in toothache and other dental problems.

Let’s take a look at 10 foods that are bad for your teeth.


Popcorn is one snack we all love to munch on whenever we feel like it. But these buttered puffs cling to the teeth and their uneven edges can cut our gums! You must be careful of the crunchy kernels as they can lead to cracked teeth if you bite them too hard.

Sugar-Loaded Sweets and Hard Candies

Sweets and candies linger in the mouth for a while as they take time to dissolve completely. They aren’t beneficial for our health in any way. In fact, they can cause some serious dental emergencies like cuts on the gums or cracked teeth. Since these candies take so much time to dissolve, it gets hard for the saliva to wash away the sugar which ultimately leads to cavity formation.

Sodas and Soft Drinks

Carbonated drinks and sodas contain acid which corrodes the teeth enamel and can cause deep cavities. Even diet sodas and sugarless drinks are not good since they also contain a large amount of acid that softens the teeth structure and makes it more vulnerable to damage. Always ensure to sip some water after you consume such drinks.

Potato Chips

Potato chips are the go-to snack for many of us. However, when it comes to dental health, potato chips can be really harmful. Loaded with starch, this delicious snack, when chewed, sticks between the teeth and feed plaque-causing bacteria. Other starchy foods like corn chips, white bread also cause the same kind of damage.


An alcoholic drink is immensely dehydrating for the body, including your mouth. Excessive consumption of alcohol can reduce the flow of saliva over a period of time which in turn leads to tooth erosion and oral infections such as gum disease. When there’s not enough saliva in your mouth to flush the cavity-causing bacteria, the chances of tooth decay increase dramatically. Moreover, alcohol may also cause mouth cancer.


Yes, ice! Many have a habit of chewing ice cubes as they can be very refreshing and are free of any sugar or additives. Even though ice is not potentially threatening to your overall health, it can have a bad effect on your pearly whites. When you chew a hard substance like ice, your teeth become more prone to a dental emergency such as a cracked tooth or damaged enamel.

Citrus Fruits

Although citrus fruits are a great source of enriching vitamins, they are also extremely high on acid! These fruits can aggravate your mouth sores and further promote tooth decay. Always ensure to drink plenty of water once you consume them. When drinking a citric drink, try and use a straw.

Dry Fruits and Nuts

Dry fruits are packed with rich nutrition and are way healthier than processed snacks. But the fact remains that these dehydrated nuts are also loaded with lots of sugar and tend to cling on the surface of the teeth. They can promote the growth of bacteria in your mouth if you do not brush your teeth after eating them.

Caffeinated Beverages

Drinks like tea and coffee tint your teeth with a brownish stain that looks very unflattering. Moreover, when sugar is added to these drinks, they make your molars sticky, which increases the number of plaque-causing bacteria. Overconsumption of these beverages leaves your mouth dry. So drink as much water as you can to keep the damage minimal.


Most of the pickles contain vinegar which is acidic and causes tooth decay. It can further cause staining and wear off the enamel from your teeth. Some pickles also include sugar which contributes to cavity formation.

To maintain that beautiful smile, try to avoid the above-mentioned foods or consume them in a limited amount. Brushing and flossing after having meals can greatly help to contain the damage caused by them.
