Does anybody know what role tanic acid has, in healing? Does it actually "heal" or just stop the bleeding? They tell you to bite down on tea bags after oral surgery to stop the bleeding, but they never tell you to bite down on them later. A friend of mine did regularly for about 2 or 3 days after having his wisdom teeth pulled, and his sockets closed right up (Of course he was doing his salt water rinse, regularly, too). Was this the salt water doing all the healing or did the tea bags help? Does anyone know? :confused:
