1. munch on apples. Dr. John Buzato, president of the American Orthodontists Association, said that it is best to avoid eating hard and brittle fruits and vegetables such as apples and carrots directly, which are the biggest culprit in tooth cracking. These foods can be cut into small pieces to eat. Similarly, chewing ice cubes can also cause teeth to break.

2. Tear the package with your teeth. It is more convenient for some people to tear open the package and open the bottle cap with their teeth, which may easily cause the teeth to break or shift, and the germs on the package will quietly enter the mouth, affecting human health.
