hello thanks for consulting at hcm..may be you have an high point in your filling resulting in premature contact on the right side and your bite is not in sync,,,also one more reason for premature contact could be long duration of mouth opening might have resulted in slight
tmj dysfunction,, so you need to take rest for that joint, by using muscle relaxants and avoid eating hard food, avoid opening your mouth widely, give hot and
cold fermentation to that joint,,you could grind the high point in your fillings if any,, if you have night grinding of teeth,,you may need night guard,, so you definitely need a consult with a
dentist, if you have tmj clinic in the area visit them,, hope it helps,,take care,,
