If you suspect abscessed tooth, it is highly recommended to see your dentist as soon as possible. A root canal may be necessary to remove the infected tissue. Failure to have an abscess treated promptly could result in the advancement of the infection, which may invade further into the bone and surrounding tissue.
Rinsing with warm salt water two to three times a day may help to relieve a toothache caused by an abscess. Salt water works as an antiseptic to remove bacteria from the infected area.
