Hi 2th,
The situation you've described has become more common with the proliferation of white (tooth-coloured) fillings. In yesteryear's, when most Dentists still used amalgam (silver) fillings, imperfections (bumps, edges, lips etc) could be easily spotted. Since today's filling materials blend naturally into your teeth, it's more difficult to spot these imperfections. Patients won't notice during the initial filling appointment since they still have freezing in. Later, when the freezing wears off, you notice it either with your tongue or your bite feels off. I always tell patients to be aware that this can occur and to simply call us back (if necessary) and request an adjustment or smooth.
Therefore, to answer your question. It's entirely common and yes, you should call your office and request a smooth....You'll be in & out in 5 minutes.
