I have a small pink lump behind my bottom molar that is sensitive (but not painfully so) to chewing or touching. When I touched it this morning, I saw that the part of the gum that touches/is up against the back of the molar is bloody. Should I be concerned or will this heal itself? I have a very steady and healthy diet that does not change.
This is due to the impacted wisdom tooth in the molar region. You should visit your dentist .get an x-ray of that region .this x-ray will decide the treatment. If there is space for the tooth to come out, then the flap over the impacted tooth has to be removed[operculectomy].if the tooth is in horizontal position, the tooth has to be removed. Thank you.
