What is the best method to drain a dental abscess?

Scalpel by denitsr: The method of draining an abscess depends greatly on the location of the abscess. Some can not be reached to drain. Typically, an oral surgeon or a general dentist can drain near surface abscess with a scalpel and place a drain to ensure it drains completely. I would not attempt to do it yourself since there are anatomical considerations that make may make that dangerous.

Dentist or oral surg: The cause of the dental abscess is the critical information that needs to be known. It could be caused by an infected nerve in a tooth or also an infection in the gum tissue. I agree with the other answers that you should not attempt to drain it yourself. The infection could spread into the surrounding tissues and blood stream, creating more complications.

Very carefully: The best method to drain a dental abscess is to have it done carefully and by someone who has experience in treating dental abscesses.
