Avoid brushing your teeth with or without toothpaste for the first 24 hours. After 24 hours, you may brush lightly avoiding the extraction site. Avoid mouthwash and rinsing aggressively. It is best to rinse your mouth gently with salt water (half a teaspoon of salt to 8 oz. of warm water). Empty your mouth of the saltwater without spiting to prevent dislodging the blod clot.
