Nightguard-to protect teeth from damage of night time grinding (bruxism). 

NTI- a device that prevents medically diagnosed migraine pain, tension-type headache, and jaw disorders ("TMJ"), through the reduction of trigeminally innervated muscular activity. Full-coverage bite guards increase clenching activity for some patients by providing an ideal clenching surface for canines and molars. The NTI-tss Plus discludes all posteriors and reduces clenching intensity by nearly 70%.  The NTI-tss Plus is smaller, less bulky and won't trigger a gag reflex. Because it is more comfortable, patients actually wear it.
