How important is it to correct a change in my bite? I recently began treatment for sleep apnea with a custom-fitted oral appliance - a mouth piece that I wear at night to pull my jaw forward.  This has done an excellent job in preventing snoring, but has altered my bite.  My dentist was very concerned by this, but the doctor that fitted the device (also a dentist) indicated that a change in bite is not serious - nothing more than an annoyance.  The change in bite does not bother me, but I am afraid it will cause damage to my teeth down the road.  Is this something that I should be concerened about?  Do I need to get the bite corrected?  I'm kind of in a bad situation where I have to choose between the effective treatment for sleep apnea, and the bite problem.

Summarized question: What is the long-term effect of a custom-fitted oral appliance that is causing a change in my bite?
