I had a crown put on a tooth in July. The dentist said bite was fine but adjusted it just in case. two months later I developed tooth sensitity on the outside surface of the tooth w/ cold sensitivity. Went back to dentist and he did xray, tapping, ice tests, and said the tooth looks fine and thought it was from grinding teeth . Sensodyne toothpaste took discomfort away for a while but its still here. I can chew fine its just soft touche/pressure that irritate tooth. Any ideas?
Tooth Sensitivity for over 5 Months on New Crown

5 Month Sensitivity
Sensitivity After New Crown
It is common to have some sensitivity following the placement of a new crown. It sounds as though it is somewhat improving, but not completely gone yet. I would say that you should give it more time. Your dentist is correct in stating that you could be grinding and the minor differences in your bite from the new crown could be causing the tooth to stay bruised. I would consider an occlusal guard that you would wear at night to see if the remaining discomfort subsides. If it does not, then perhaps seeing an endodontist for the potential need for a root canal would be a good idea. Good luck.
Tooth Sensitivity for over 5 Months on New Crown?
Some sensitivity after a new crown can be normal. I tell my patients that on average it goes away in about a week. In some circumstances if the tooth needed extensive, deep work, then it could take a few weeks for it to settle in.
Since the crown was fine to start with, I'm suspecting that the sensitivity is coming from one of two routes.
One, after all of the treatment was done, you may have had a small amount of gum recession at the edge of the crown. This exposes the edge of the root.
Two, it's possible that some of the cement could have not cured well or have washed out of the edge (margin) of the crown. I think this is less likely to happen.
For either of these scenarios, I would keep working with the Sensodyne. It can lessen the sensitivity over time. In my office we also use a lot of prescription strength Fluorides-like Fluoridex. It can also have a profound desensitizing effect.
It IS possible that it is related to your bite. It could also come from some extremely small discrepancy in your bite. Your cosmetic dentist may need to look at it again.
Any tooth that has had a crown has had a significant amount of disease before that. Any time the tooth has been through that much there is a small chance (6%) that the nerve can be affected and actually die. You can have an abscess (which slowly becomes a toothache or a swelling), or a "quite" abscess, where it never hurts a lot.
If the crown or tooth keeps acting suspiciously, then you may need another X-ray or the bite looked at again.

Post-op Sensitivity on a Crown
If your dentist feels it is due to bruxism, maybe he could adjust the bite on the crown enough to where you do not touch it for a short while to see if that is in fact the cause. If so, a nightguard would be in order especially if you have any wear patterns in your teeth. If any tooth structure is showing between the margin of the crown and the gumline, it is possible this is the source of the sensitivity and could be coated with a desensitizing agent to seal it better. The other possibility is the nerve did not survive the procedure and will need to have a root canal done. The nerve in teeth have a poor healing ability and the dental work it has had done over the years can add up to where the nerve cannot tolerate the procedure and problems develop later.
