Treatment for tooth pain depends on the cause, and some treatment options include root canal, antibiotic medication and phototherapy, explains WebMD. Tooth pain can occur due to a bacterial infection or a cavity.
A dentist recommends a root canal if there is an infection in the nerve of the tooth, notes WebMD. This occurs when bacteria get in the inner parts of the tooth leading to an infection. Patients take antibiotics if there is a swelling of the jaw, or they are experiencing fever. Dentists may use phototherapy alongside a cold laser to ease pain and inflammation that occurs due to the tooth pain.
