Yes : Yes you should call your dentist. The solution might be a simple adjustment, but it has to be performed by your dentist personally.

Your : Your symptoms are not unusual after having a metallic filling placed. This may be caused by a number of factors, either alone or in combination: 1. The nerve in the tooth was disturbed by the action of cutting on the tooth, either through vibration or heat produced. This can lead to a temporary irritation to the nerve that should resolve over the course of a few days. 2. The filling was very large and deep. Because of the materials ability to transmit changes in temperature more easily than tooth structure, the nerve may be reacting to this stimulus. Again this should decrease with time as the nerve lays down a additional layer of material, repairative dentin, that will act as an additional insulation. 3. The filling may be left over contoured. This will create a sensation of the filling being "high" and cause the tooth to be sensitive to biting pressure or changes in temperature. This situation needs to be addressed by your dentist by smoothing down the filling. Once done the tooth should begin to feel better. Failure to do this may lead to the filling fracturing. 4. Occasionally you may have a temporary metallic taste in the mouth after getting a new metallic filling, thus should also resolve in a sort time. If you have situation #3 contact your dentist tomorrow. If the symptoms do not begin to resolve from the other reasons in a week or so contact your dentist for evaluation.

Any : Any treatment such as fillings, inlays or inlays where the dental turbine or hand piece is used it could be considered an insult to the tooth, its undetectable vibration and heat produced will affect in most instances reversibly or seldomly irreversible the nerve of the tooth. In most instances the sensitivity will go away after a couple of weeks, you should communicate at all times your condition or sensitivity to your dentist. Good luck.
