Can an adult tooth be pushed back in after being knocked out?
If it is the whole tooth then gently push it back into the socket. Fold a clean handkerchief into a pad and use this to bite on to keep the tooth in place. Contact your dentist immediately. If the tooth is dirty, do not scrub it first. Rinse it carefully in milk or cold water before putting it back into the socket. If you can’t push it back in then put it in some milk or saliva and contact your dentist immediately. People playing rugby or other contact sports should wear mouthguards for protection. It’s a good idea to ask your dentist about getting one made professionally.
