I had some serious TMJ problems which, because of unusual spinal problems, promised to get more serious–something, I assure you, I did not want. Both my splint (worn at night) and my orthotic partial work perfectly to keep my jaw aligned regardless of my spinal condition.. This is great because I still have more spinal issues to get through (and am working hard on them). So the dental science is really good. And everyone here is top notch–spirited, friendly, timely, available, and open to questions.
