Hello,

Thanks for writing to us.

I would like you to know that due to night grinding or bruxism the biting surfaces of the teeth becomes flat, the enamel which protects the nerves within the tooth is worn off with continuous pressure. This the reason why teeth become sensitive.

The swelling over the TMJ joint can be from slight inflammation , I suggest you to apply alternate hot and cold compresses over the swelling.

Do not chew hard foods for a while, you can take a painkiller but only twice/day after meals only.
If the swelling does not subside in 3-5 days or even if it increases in size then kindly see your dentist.
Also, continue wearing the mouth piece as advised by your dentist.

I hope this answer was useful,

Kindly write back if you have any further queries.

I wish you good health,

Take care.
