Maintaining good teeth is a struggle for everyone. Even if you were one of the lucky ones and skipped the unfortunate braces stage, you still have to keep your teeth in good shape.

Brushing, flossing, whitening- and even then, your teeth can get damaged by what you eat. If you’re trying to keep your pearly whites extra pearly, this is what you should avoid eating:

1Nuts

Even though everyone loves nuts, the way we eat them can be extremely damaging to teeth. You can still eat all the nuts you like, but don’t bite them with your front teeth!

2Ice

If chewing on ice is your guilty pleasure, it’s time to find a new one. Chewing on ice can be really damaging to the teeth, in addition to chewing on hard candies.

3Seeds

Seeds can easily get jammed in between teeth and under the gums, which in addition to being painful can cause an abscess. If you do eat seeds, brush your teeth after!

4Sticky Sugars

So eating lots of dried fruit isn’t a good idea after all. Sugar causes your enamel to decay when the sugar breaks down the bacteria in your mouth. If you do eat dried fruit or anything high in sugar, drink water or brush your teeth right after.

5Acidic Food

Foods high in acidity are the worst for teeth. Acidity throws off-balance between the good and bad bacteria in your mouth, and too much harmful bacteria can cause inflammation in your mouth. Ouch. Coke is one of the worst things for your teeth, so avoid drinking that.

Coffee, however, is only a little bit acidic- but it’s a diuretic which means it can dry out of your mouth, which you don’t want either. Either way- minimal consumption of acidic foods is critical.
