Signs of night-time grinding
  • Do you have teeth with defects or sharp edges?
  • Are your front teeth or canines heavily worn down?
  • Does your lower jaw pivot when opening and closing?
    Look in a mirror. Open and close your mouth slowly.
    Check the centre line of your front teeth.

Relief for the chewing muscles

It can only be ascertained by a full examination if pain is caused by night time tooth grinding or clenching. If necessary, a device can be fitted which is worn at night.

It can be easily inserted over the front teeth, and prevents nocturnal tooth grinding and clenching.

How does the device work?

In principle, it is simple. A device on the front teeth acts as a protective barrier, and will limit the strength of the jaw muscles. You can prove this yourself.

The pencil test

Place a pencil between your teeth at the side of your mouth. Bite down firmly, and at the same time feel the muscles in the temple area contract. Repeat the process with the pencil between your front teeth. It is no longer possible to bite down as hard! In a similar way, the FOS device prevents hard biting at night.
