Treating a cavity in a wisdom tooth depends on its position. Because wisdom teeth are hard to clean, the most common and practical option is extraction (removal) to prevent future decay. If the tooth is fully erupted, straight, and easy to reach, your dentist can restore it with a standard dental filling. Note that medicines cannot cure a cavity. However, over-the-counter pain relievers like ibuprofen or acetaminophen can manage temporary discomfort, and a dentist may prescribe antibiotics like amoxicillin if an infection is present. Please schedule a dental exam so they can take an X-ray and find the best, most comfortable solution for you.
