1. Eating fruit all day

A bunch of grapes in the neighborhood where you snack all day: in itself a healthy way of snacking, but not best for your teeth. The bacteria in your mouth turn the fruit sugars into acid and that affects your tooth enamel. Your saliva will neutralize the acidity in your mouth after dinner, but if you eat foods with sugars or acids all the time, you will not get the chance.

It is therefore best to eat or drink a maximum of seven times a day: three meals and four snacks. You prefer to limit fruit to one or two times a day.
