A while ago, I had oral ulcers. At that time, I thought it was a wisdom tooth pain. I went to the hospital to take a CT scan. The dentist told me that I needed to remove the two wisdom teeth on the right side of the CT scan, because the upper teeth had grown into the maxillary sinus, and the lower wisdom teeth were not in the right position. Is she right? My oral ulcers are healed, and my wisdom teeth have no other symptoms. Do I need to pull out my wisdom teeth?
