I have a small white bump on my gum where my widom tooth used to be. the gum there is also swollen and my jaw and ear hurt. what could it be?

Healing wisdom area: How long ago was the tooth removed? It could be an infection, an exposed piece of bone, a bone fragment working its way to the surface, a small piece of tooth or something else. See you dentist for a personal clinical exam and evaluation. If the tooth was removed recently, this is part of normal aftercare and the responsibility of the surgeon, although it's your responsibility to call and ask.

Gingival abscess: A gum abscess usually requires treatment; otherwise it can worsen and result in the destruction of the surrounding tissue. See your dentist for evaluation and treatment.

See oral surgeon: Could be infected area, bone fragment. Might be unrelated TMJ problem. Best advice is to see oral surgeon who did extraction for exam/treatment.
