Best way to treat a tooth infection
Treat a tooth infection by removing or draining its source, using root canal treatment or extraction when the tooth cannot be retained.
The short answer
A tooth infection is treated by removing or draining the infected source, usually with root canal treatment or extraction, while antibiotics are reserved for selected situations such as spreading infection or systemic illness.
How can bacteria reach the inside of a tooth?
Bacteria can enter through deep decay, a crack, a failed restoration, or gum disease and reach the pulp or tissues around the root. Diagnosis combines symptoms, tooth vitality tests, percussion, gum findings, and dental imaging.
What should you do after noticing a tooth infection?
Arrange prompt dental care and keep the area clean. Do not place heat, chemicals, or tablets on the tooth, and do not assume that pain stopping means the infection has resolved.
Which signs of tooth infection need urgent care?
Facial swelling, fever, pus, worsening illness, difficulty swallowing or breathing, or trouble opening the mouth requires urgent care. A dental abscess should not be left to resolve without treatment.
What should you ask about treating the infected tooth?
Ask whether the pulp is involved, whether the tooth can be restored, why root canal treatment or extraction is recommended, and whether drainage, a crown, or antibiotics is indicated.
