A day and night appliance is a custom-made oral device designed to support proper jaw alignment and reduce stress on the temporomandibular joint (TMJ). Worn both during the day and at night, these appliances aim to lessen the effects of clenching, grinding, and tension, which may reduce facial pain and improve jaw function.
Day and Night Oral Appliances
One appliance for the hours you are awake, one for the hours you sleep. Both are made for your bite, so the jaw joint is supported around the clock instead of only at bedtime.
Why Two Appliances
Every appliance we make is built for one patient and one bite. Instead of a single device worn only at bedtime, we pair a daytime appliance with a nighttime appliance so the jaw is supported around the clock. Both are part of our wider TMJ therapy care in Payson. Call (385) 446-4947 to find out which one fits your symptoms.

Day vs. Night
The day appliance helps reduce clenching strain; the night appliance helps protect the teeth and supports the airway during sleep.

Day Appliance • Night Appliance

Day Appliance
The day appliance covers the daytime function half of treatment. Worn through the hours you are awake, it supports proper jaw alignment and is designed to reduce stress on the temporomandibular joint, helping minimize the clenching and tension that can contribute to facial pain and reduced jaw function.
Getting fitted
- Custom-made from a digital impression of your bite
- Checked and adjusted so it does not add strain
- Worn through waking hours as your jaw adjusts
- Follow-up visits fine-tune the appliance as your jaw settles
Best for: daytime jaw clenching, afternoon jaw fatigue or soreness, teeth grinding while awake.

Night Appliance
A standard night guard only shields the teeth from grinding. A TMJ night appliance is designed to help relax the jaw muscles and support a more comfortable jaw position, based on what your evaluation finds. When the airway is also involved, the same appliance can gently bring the lower jaw and tongue forward to help keep the airway open — the approach we use for sleep appliances .

A night appliance can gently reposition the lower jaw and tongue to help support airflow during sleep. For appropriately selected patients this may ease breathing, reduce snoring, and improve sleep quality. Our appliances are customized to your exact bite and airway needs, and for patients who qualify, may offer an alternative to CPAP therapy or work alongside it.
