If you have problems with migraine headaches, tired sore jaw muscles upon awakening, or grinding your teeth at night, you should consider the only FDA approved oral appliance specifically designed for releif of these problems.
It's called an NTI (Nociceptive Trigeminal Inhibition Appliance)and is a small appliance made of clear acrylic which fits over the upper front teeth. It is comfortable to wear and helps control the discomfort associated with bruxism(tooth grinding).
The NTI is easy for you to have made. You usually don't have to have impressions taken and it is very affordable compared to other forms of headache and TMJ treatment.
