I have herniated disc in my tmj &dr.said use a night guard &for 6 months every night for an effect to occur is there anything more to do is it enough?

Rest: Surgery. But that is a last resort. The injury needs rest but that is hard to do. Night guard, may need to wear full time, soft foods, no wide opening. Rest at least 3 weeks before you "test it".

Disc: Staying on soft diet for the first few weeks might help. However, if your MRI shows disc adhesion and excess scarring, the night guard will not help and would need arthroplasty.

Yes: Find a neuromuscular dentist in your area and have consult with them. Let them help you to find your proper physiologic bite and jaw position for you, this is very important to your long term prognosis.

Nightguard for TMJD?: It is very unclear what 'herniated disc' means. There is no such a term for the disc in the tm joint. I think you have been misdiagnosed. It can't be considered a treatment option for tmjd any use of night guard. Find a dr. That have been trained in tmjd and get complete work up. There are tests that you'll need to have done before you will be diagnosed with certain stage of joint problem.

Splint: Try a splint stay away from chewing gums and eating hard food.

Orthosis: Try to have an orthosis made that allows your retrodiskal tissue and bilaminar zone to be free from being pinched. Also, you may want to work with atlas orthagonist with a dentist on your head/neck muscles along with your TMJ issues.

Bite splint: A simple bite guard may not be sufficient. A full arch bite splint, adjusted precisely with bilateral simultaneous even intensity contacts and shallow 'anterior guidance' (slight ramping) is a normal approach to treatment. Sometimes a guard that anteriorly positions you lower jaw to 'recapture' the disk is used, but your best bet is to have a dentist well trained in bite splint therapy evaluate you.

TMJ expert: Yes. Make sure you're being managed by a TMJ expert. Other treatments possible. Any dentist can be a TMJ expert with the proper training and experience. Most commonly, oral surgeons, prosthodontists, and orofacial pain specialists. Ask your MD, your dentist and your dental society for referrals.
