The day after the extraction, gently rinse your mouth with warm salt water (half a teaspoon salt in an 8 oz. glass of warm water) after meals to keep food particles out of the extraction site. But remember not to rinse your mouth vigorously, as this may dislodge the blood clot. If you have hypertension, discuss with your dentist whether you should rinse with salt water. Avoid using a mouthrinse or mouthwash during this early healing period unless your dentist advises you to do so.
When choosing oral hygiene products, look for those that carry the American Dental Association's Seal of Acceptance -- a sign that a product has met ADA criteria for safety and effectiveness.
