The clenching and grinding (bruxing) of teeth can lead to headache, toothache, excessive tooth wear, and muscle ache in the head, neck, and shoulder area. Most clenching and grinding forces are exerted during the night when you are not aware of it. How have you been sleeping lately? Do you wake up refreshed or are your muscles tight? The use of a properly constructed device followed up by a painless series of bite adjustments can lessen or even eliminate these harmful activities.
