Sensitive Teeth Ask The Dentist John Purpura

Question:
Since having permanent crowns put on my teeth, I have sensitivity problem with hot, cold, sore, and sweet now. It still hurts.

I still cannot eat/drink hot/cold/sweet/sore food, tea, and milk also without experiencing severe intense pain. Not throbbing, just long lasting and excruciating. Sir, how can this sensitivity be taken care of? ...Visitor from New Dehli, India

Answer:
Oftentimes justification for having a crown placed is because there has been a lot of damage to the tooth. This damage may have come from bacteria or trauma. Also the preparation of the tooth for the crown is a form of trauma.

The nerve inside the tooth may not be able to recover from all of the trauma and thus dies. While it is dying there can be some pain. Also if the entire tooth is not covered by the crown, some of the tooth may be exposed to the outside world and when the cold, heat and sweets contacts the exposed tooth there can be pain from that.

I would recomend seeing a dentist and having the crown first examined to see if there is an open margin (the area where the crown contacts the tooth) and/or to examine for the need to have a root canal (a process whereby the nerve is removed form the tooth).

John Purpura, DDS
