Hi,
As per your condition it may happen that you may have worn out chewing surfaces of teeth and may require caps on such teeth to relax your jaw muscles..In other case it may be normal and won't cause any bigger issue in future..
Take care.
Next Steps
Better to get a dental consultation done soon to clarify your problem.
Health Tips
Don't be over cautious for your jaw.. It will tighten your jaw muscles and may further be more problematic.. So just keep calm and relax.
