It is very important to try to avoid acidic foods and drinks between meals, because there isn’t as much saliva in your mouth at these times to protect your teeth. Also, be sure to wait about an hour to clean your teeth after eating. If you brush while the acids are still in your mouth you are removing some of your teeth’s surface. If you wait about an hour the saliva will help your teeth battle the acid so it is safe to brush. Try to finish your meals with a little cheese or milk as these products help cut down on the acid in your mouth.
