A tooth could ache due to a variety reasons. Most commonly they ache due to decay and gum disease. The treatment of an aching tooth depends on identifying the reason for the ache. Teeth aching due to decay requires root canal therapy or extraction if the tooth is badly broken down. Teeth aching due to gum disease require gum cleaning, medication and in advanced cases root canal therapy or extraction.
Treatment for a toothache depends on the cause of the pain and how much damage is present. If a cavity is causing the toothache, your dentist will fill the cavity or possibly extract the tooth, if necessary. A root canal might be needed if the cause of the toothache is determined to be an infection of the tooth's nerve. Bacteria that have worked their way into the inner aspects of the tooth cause such an infection. An antibiotic may be prescribed if there is fever or swelling of the jaw.
For a periodontal abscess, a simple drainage procedure is performed under local anesthesia. Additionally, the affected gum pocket is thoroughly cleaned to remove any tartar buildup and debris. Once the area has been cleaned up, the pocket is irrigated with an antimicrobial rinse. Sometimes, antibiotics are locally-administered into the pocket to further aid in healing. Depending on the extent of the abscess, oral antibiotics may also be prescribed. A follow-up visit is recommended to make sure the infection has completely resolved and develop a plan to properly maintain the area.
