Teeth Grinding Vs. Clenching

Tooth grinding and clenching are common phenomenon amongst us humans and is a primal, involuntary, physiological response to stress, anxiety, concentrating, excessive physical exertion, recreational drug use and altered tooth positions (eg. due to a new filling).

Tooth grinding is where there are large, muscular forces clamping the teeth together, combined with side-ways movement, creating flat worn surfaces on the teeth. This is particularly noticeable across the front teeth.

Tooth clenching involves stronger forces again, gripping the teeth in a stationary position and intense contracting of the jaw muscles. The forces in tooth clenching can be up to 7 times the forces we use to eat our food. Clenching does not create the same wear as grinding, but instead you will see visible, vertical cracks in the teeth when they are dry. These stain brown over time and become more noticeable (another reason why clenching is often left undiagnosed until later adulthood).

The symptoms of the tooth grinding and clenching are reasonably the same, although they look slightly differently due to the differences in their nature.

The symptoms include:

The issue is that tooth grinding and clenching damages your teeth in a slow, but really serious and permanent way. Initially you may experience some or none of the symptoms above, but over the course of your life, major damage can be done.
