I am unemployed at the moment just switching between jobs. I think one of my back teeth needs to come out. I woke up with my right cheek swollen and a purple bruise on the gumline right above the tooth. The tooth and gumline are just irritating no pain I dont want it to be infected so I can't keep it in. Would it be safe to just pull out the tooth myself? i've been gargling salt water to keep the swelling down. what would u recommend?
