Some remedies for toothache include root canal, tooth extraction, antibiotics, filling and phototherapy with a cold laser, according to WebMD. The type of treatment a dentist chooses to use depends on the cause of the toothache. Dentists use X-rays to identify the cause of toothaches.
To treat toothaches caused by tooth decay, dentists remove the decayed area and replace it with filling. Root canal treatment is necessary if there is an infected pulp inside the tooth, notes NHS Choices. Dentists may prescribe antibiotics if there is pain or swelling. Phototherapy with a cold laser eases the pain and inflammation caused by toothache. If these methods fail, a patient undergoes tooth extraction.
