The Nightbite TMJGuard

Grinding and clenching don't stop on their own.

  • Waking up with a sore, tight jaw
  • Morning headaches that start at the temples
  • Worn-down, sensitive teeth
  • Clicking or popping when you chew
  • Restless, lower-quality sleep

Store-bought guards are bulky, generic, and half of them end up in a drawer within a month. Dentist guards work — but cost hundreds and take weeks to get.
