I Had Four Front Bottom Teeth Pulled And A Few

I had four front bottom teeth pulled and a few days later i noticed what i thought was pieces of tooth in my gums and i just kept finding more spots .i went back in he said it was exposed bone and should heal in couple weeks if not he would stictch my gums after that. Well my gums just keep getting more splits in them. The first four or five days i wasin excruciating pain and my whole chin was purple. Looked like i had a purple goatee.ha ha. But im wondering if i should be doing something besides gargling salt water.
