which doctor to consult for mouth infection

For a persistent and painful sore in your mouth like you’re describing, the best starting point is usually a visit to a dentist. Dentists specialize in oral health issues and can assess whether the sore is related to dental hygiene, an oral infection, or something else entirely. They can also recommend appropriate treatment and may prescribe medication if an infection is present. If the dentist determines it’s something beyond their scope, like a deep tissue infection or the need for surgery, they may refer you to an oral surgeon. Your general practitioner (GP) could provide initial advice but typically wouldn’t specialize in diagnosing or treating oral-specific conditions as expertly as a dentist would. Based on what you’ve described, this seems like it could be more than a simple canker sore, particularly if there’s swelling and it’s painful to eat or drink. These symptoms could indicate an oral infection that might require antibiotics or other specific dental treatments. During the appointment, expect the dentist to examine your mouth and potentially take an X-ray if they suspect something related to tooth roots or a deeper issue. If you notice any increased swelling, fever, or inability to open your mouth, it’s essential to seek medical attention promptly, as these could be symptoms of a more significant infection. In any case, it’s wise not to delay seeking help because oral infections can sometimes lead to more serious complications if untreated. So, setting up an appointment sooner would be advisable, given the duration and nature of your symptoms.
