Question: what to do after having tooth out?
Answer: Don't rinse your mouth out for at least 24 hours after a tooth removal. ... 
After 24 hours, rinse gently with a salt water mouthwash (made using salt and hot, but not boiling water), four times a day to keep the area clean.
Eat soft food once you first have your tooth removed, so you don't have to chew much.
