Root canal sensitivity to hot

[Su G]

I had a root canal a year ago but still have pain only with hot things not cold, as well as a tender gum at points around the tooth and some pain on chewing at times. Does this the root canal need redoing? My nhs dentist said sensitivity to cold as well as hot would indicate it needed redoing, he says hot sensitivity alone doesn’t indicate this.

I would need to see an x-ray to comment. There might be a problem with the root canal, but would need to confirm first with an x-ray.
