question: 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
