<s>[INST] I need a root canal treatment done but my tooth is in condition though I think it has  split and also there is a swelling in my gum. Also my gums are very sensitive there is a burning sensation when I eat anything spicy. I am 58 years old and in good health [/INST] Thanks for using Chat Doctor. Read your query. Swelling the gum and decayed tooth suggests abscess formation in relation to that tooth. I would advise you to visit your local dentist and get it evaluated with a radiograph after which the root canal treatment can be confirmed. If the tooth is split, it will be removed. For sensitive gums, get your teeth cleaned professionally and then use a desensitizing toothpaste like sensory for a while and do chlorhexidine mouth wash gargling. Hope this was beneficial. Thanks and regards. </s>
