Brushing your teeth after eating
Many advertisers in the oral hygiene industry are promoting the idea that we should brush our teeth after each meal.
According to the Mayo Clinic, though, we should wait at least 30 minutes after each meal to clean our teeth. Why?
Because many of the foods we eat temporarily weaken the tooth enamel, if you brush your teeth right after eating those foods, you actually increase the likelihood of damaging your enamel. The foods that have the highest impact are the citrus ones.
However, if you wait for 30 minutes or more post-meal, your saliva will naturally eliminate the food acid in your mouth and the tooth enamel will return to its natural, strong texture.
