White canker sore on the side of my mouth near wisdom teeth. Oral cancer?
Patient: Hi Dr, I have had a white canker sore on the side of my mouth where I have two wisdom teeth that I haven t removed yet. This canker sore has erupted in the same spot many times, and I bite down on it usually due to the wisdom molar teeth at the back of my mouth near the Palatoglossal arch. It comes and goes and I am worried it s cancer every time... My question is should I Be worried? Doctor: hi there, a recurrrent sore or white patch in the mucosa could be due to the constant irritaion caused by the by the tooth. It would be a good idea to get the offending source removed because constant irritation can be one of the eitiological factor for malignancy. Do get an exfoliation cytology done of the site and that will help you rule out malignancy or even a biopsy can be done to get over your worry. Take care.
