Was the job done correctly?

[gil]

The crown is now over one year old. In the last few days, it started to be painful in contact with heat or cold. It goes away after a while. Should I go back to my dentist to have it checked? Will that generate a cost? Was the job not done correctly? Thank you very much for your advice. Gil

Perhaps the nerve is dying; this happens in 5-10% of crowned teeth. Maybe this is something that will pass and I would advise you to wait a bit longer. Certainly if the pain becomes more serious you will have to go to a dentist and that will incur a fee. We can't tell if the treatment was done correctly.
