A tooth abscess is a local collection of pus in or around the tooth and is best treated by draining the pus. This should be done as soon as possible to prevent the spread of the infection to other parts of the head and neck. It can be done by a local procedure in the mouth, through a root canal or by removing the tooth completely. Antibiotics are generally not needed if the pus is drained. In fact, scientific studies have shown that antibiotics are unnecessary for treating tooth abscesses.
NOTE: Antibiotics are NOT recommended to settle the infection before draining the abscess – Drainage as soon as possible is the therapy of choice.
