How to prevent this pain?
Brush at least 3 times each day. Floss once each day. Visit your dentist twice per year for regular cleanings and checkups. Rinse once each day for 1 minute with Listerine. The ingredients in Listerine are approved by the American Dental Association to kill bacteria responsible for causing gingivitis.
