[|Human|] I am having a problem with an upper tooth that had a root canal done on it about 5 years ago.  The is swelling far above the tooth where the gum and the cheek meet.  I have no pain but the is area is very sensitive to touch and discomfort is felt when pressure is applied to the area.  There is also swelling.  I do not want to return to the endodontist who performed the root canal, as I have no confidence in him
[|AI|]  Hi, Thanks for asking the query, Pain and swelling can be due to re-infection of the tooth or due to food lodgment between the tooth and cap surface if the tooth is capped. I would suggest you to visit the Dentist and get an x-ray done, if necessary you can go for the pretreatment of the tooth or else you can go for complete mouth scaling and polishing. Take antibiotics and analgesic course under prescription of your Dentist. Take care!
