Can bruxism cause changes to your facial structure?

Yes: It can significantly increase the size of your jaw muscles.

Face changes: Yes, the muscles in your face are affected by clenching or bruxism. These muscles can become very large and affect either the lower jaw line or the side of the face.

In what aspects?: Some people with long standing clenching or grinding habits show an increased size of the muscles along the cheek area. Is there something else you are referring to?

Absolutely: You are working your muscles, so they may enlarge and change your facial contours. As you wear your teeth down, the chin and nose get closer together -- your face starts to collapse, and the lines from your nose to the corners of your mouth tend to deepen. The muscles in your chin may also distort and change your profile. As your face collapses, the jaw rotates more and your chin may prodrude.

Yes: Yes, by enlargement of the jaw clenching muscles. You'll get a square jaw appearance. See TMJ-orofacial doc to help with problem.

Bruxism: Grinding can prematurely wear out back teeth, cause muscle strain, cause jaw joint damage, and there may be some modest muscle mass increase. Please see your Dentist. Referral to an Orthodontist may be indicated.
