<s>[INST] I have a small lump under my chin and im going the doctors to get it checked tomorrow but today for some reason my four front teeth are really hurting, like an annoying pain but bearable just really sensitive it feels like do you think these are anything to do with each other? I am 18 about 8 stone and 5 foot 5 [/INST] Hello and thanks for consulting Chat Doctor.I have read your query and I think it could be an infection causing access formation. Infection under your chin below your front teeth can be due to following reasons:1. Due to cavity in the tooth2. Gum inflammation (gingivitis or periodontitis)3. Trauma from occlusion (TO)1. If you have any cavity related to those teeth you should consult a dentist. They may take an x-ray to find out the extent of infection and plan the treatment like RCT (if needed).2. If It's due to gum inflammation you can have a complete mouth cleaning done3. sometimes it can be due to TO. In that case doctor might check your bite and adjust it if necessary Hope this answers your queryRegards </s>
