Sensitive to hot and cold after root canal

[kiin]

Hi!
In January I got a root canal and in March I went to visit my dentist again as I suffered when biting, drinking/eating cold and hot. I think it's the tooth that was treated that is sensitive to hot and cold. My dentist made an x-ray and said everything would be fine, just the filling was a bit too high... And he told me that the tooth itself can't be sensitive as it's dead.
I couldn't really believe him (sensitive to cold and hot because of a high filling!?) but what else can I do as a patient.
So now there we are 1 month later, at least i can bite without suffering but I am still very sensitive to cold and hot and I think I should see him or an other dentist.
I would be happy and thankful if you could tell me if my dentist seems good to you or if I should go see another one

Did your dentist do a cold test? He/she should test the surrounding teeth as well since many times it's the tooth next to the root canal that may be sensitive.

Any Xrays to show us (before and after RCT)? Any other treatment done recently on adjacent teeth? Why was the RCT done?

yes he did, it was very difficult to locate it as I wasn't as sensitive as I thought I would be (to cold water at home I react more...). But it's surely the same tooth or one of the direct neighbors.He told me again just to wait and see!

Also when I floss there it hurts a bit on both sides

I could ask my dentist.
The RCT was done because it still hurt 1/2 year after drill. Caries was too deep, there was no treatment on any other tooth

That tooth is a complicated one to do a RCT. There is a 4th canal that most dentist including yours have a hard time with. It makes sense now why you are still temp sensitive. You may need a specialist (endodontist) to retreat it.
