the muscle issue should resolve w massage/heat packs etc-- like any other muscle spasm. the tooth
may have a pulpitis--which is an inflamed nerve from the crown
being high. it is usually reversible and should be ok. if not, the tooth may need root canal treatment, but i would not make this decision quickly. unkless the pain is severe, i'd give it weeks if not months to calm down. swelling, fever, spontaneous throbbing pain are signs that you may need root canal treatment.
