[|Human|] I have a small ish White lump with a red ring around it on the roof of my mouth toward the left side, it hurts quite alot and hurts to spit and swallow . I have had it for about 8 weeks. I have recently been to the dentist and they said the lump was nothing but they said that I needed a deep filling redone as it had chipped and become decayed again. they took an x ray to find this. I am 14 and very worried about the lump and getting the tooth refilled as I have a fear of the dentist. Any help as to what this is would be very appreciated. Thank you
[|AI|]  Dear Millie It looks like you are having periapical abscess. This happens when the decay has become deep and reached the pulp and progressed to tip of the root. The pus is now probably Chat Doctor.  Since the X-ray has been taken, it would clearly show how deep has the decay reached and whether that is the cause for your lump. In your case most likely root canal treatment is required.  The second possibility is that the tooth is decayed beneath the filling and the tooth has chipped off leading to food and plaque accumulation, which might have caused gingival abscess (abscess of gums) . In which case redoing of filling is sufficient provided the decay has not reached the pulp (X-ray will confirm this).  In either case you need not have to be scared, dentist will anesthetist the tooth during the procedure (if he doesn't then insist on it).  Visit dentist regularly and get yourself examined to prevent future problems. Take care regards
