Night Guard
A device similar to a retainer which separates the teeth and oftens relaxes the muscles which position the jaw.
A variety of configurations are used. A nightguard is indicated for people who overwork their jaws at night
and possibly risk damage to their teeth, jaw joints, and/or muscles. People who wake up withsore muscles,
facial weakness, or a jaw that is "locked" are good candidates for this device. Some types may also be used to
diagnose jaw posture problems.
