Will a night guard help with my tmj symptoms?

Perhaps: If you have tmj\tmd symptoms, see a dentist with extensive training and experience in this area to evaluate your case and suggest treatment options. It's much more complicated than just making a night guard for a patient. Night guards may or may not help and each case is different.

Generally not: If it is a hard appliance, it generally makes it worse. Only by a strategically designed soft appliance can relief be obtained. Find a dentist that is very familiar with TMJ treatment - only about 5% of dentist are trained this well.

Possibly: A nightguard can help if jaw joint issues are related to the bite.

Yes to some extend: But try to find a neuromuscular dentist in your area to help you with your TMJ issues.

Perhaps: A night guard helps with night time clenching and grinding. Many TMJ patients find this helpful.
