As funny as it sounds, much of what has been learned about the effects of serotonin on body tissues and posture comes from studying the lobster. Bruxism is an indicator of increased serotonergic tone as has been revealed from studying rats and humans.

> So does that mean if we experience SB with SSRIs, we probably already have higher than normal serotonin? And adding the SSRI just causes the SB?That's great question. One problem, though. I don't know the answer. It may be possible that stress hormones and excess noradrenergic tone could do the same thing. I'm not sure. Perhaps this is a case where there is a disruption in maintaining a balance between different neural pathways. If a benzodiazepine can reduce bruxism, then I should think that norepinephrine is involved.
