Reason: After eating just one piece of candy, your mouth becomes acidic and it can take up to an hour for the mouth’s pH balance to return to normal. The longer the teeth are exposed to acid, the greater the chance of cavities.
If you choose to eat sweets: Limit treats to one after-meal serving—the increased production of saliva during and after a meal helps to wash away acidity. Also, try to brush your teeth or at least rinse your mouth with water after eating sweets.
