It's mostly improved, getting it again tho because ive had chiropractic adjustments that change ur jaw position just by virtue of it being connected to ur neck muscles. Popping and cracking improved within a few weeks of daily(mostly daily) splint use
For about 8 months now. It helped with popping, clicking, and jaw pain and discomfort, but not so much the tinnitus. Its basically just a retainer you wear at night
