Hello,
If any recent filling (Restorations), crowns (tooth Cap) have been done the high point on those could be the reason for your problem.
If no treatment has been then it can be due to mal-occlusion (Improper biting due to improper position of teeth), TM joint related issue.
Next Steps
Consult the nearby dentist for proper evaluation (i can help to connect one in Banglore.)
