My cheek bone has went through the back of my gum what can i do?

Not cheek bone: Possibly a wisdom tooth. See a local dentist for an examination.

Telephone: Probably not cheek bone. Best thing you can do is to contact a Dentist, the professional with >10,000 hours of training in how to resolve your problem. Please don’t try to “fix” yourself as you will probably just make things worse. Pick up your telephone and call a Dentist for knowledgeable caring help. You’ll be glad you did.
