[|Human|] I have a small swelling above a front tooth and it feels tight when I move my lip.  This tooth was knocked out when I was 10 and has been a crown ever since. I did have full mouth Xrays last week and my dentist said  there was nothing wrong  I do have a pain syndrome, could it be coming from this?  Thank you
[|AI|]  Hi... Welcome to Chat Doctor . I have gone through your query and can understand your concerns... As per your complaint a swelling over the gum of the tooth that has a crown over it seems to be most probably due to re-infection in the crowned tooth and in case of the tooth is root canal treated before crown placement then it is a treatment failure. If it is not root canal treated the tooth may need root canal treatment. If the tooth is not infected then the bump can be due to gum infection leading to formation of gum boil or a gum abscess. There is a possibility that diagnosis is missed in x Ray so a repetition of x Ray can help. If there is tooth infection Root canal treatment or a re treatment if tooth is already treated needs to be done after removing the crown followed by antibiotics and painkillers will relieve. In case of gum infection Scaling following by antibiotics and topical application of gum paint will relieve. Hope this information helps. Thanks and regards. Chat Doctor.
