Negative symptoms and bruxism

Hi, my relative has negative symptoms and bruxism, could anyone please tell me if bruxism could be caused by antipsychotics?

Yep, that can be a side effect of certain medications.

Whatever the cause, would your relative try a night guard (what my dentist calls the mouthpiece I have to prevent damage from grinding my teeth)?

Yes. It’s good to get one from a dentist rather than over the counter. My own dentist is rather esoteric about it, but I can’t explain it. I don’t have mine yet. Waiting.

I have one too. It’s great to wake up without head aches.
