Jaw Clenching Day vs. Night: What the Research Says

Jaw clenching during the day and clenching your jaw at night are two different behaviors, and the research treats them that way. In Episode 4 of Jaw Awareness, Randy Clare walks through what international bruxism researchers say about awake bruxism and sleep bruxism, the 4-second brain-to-jaw sequence recorded in the sleep lab, and a one-week check-in to see which pattern may be happening to you.

You'll learn:
Why consensus papers from 2013, 2018, and 2025 describe bruxism as a behavior, not a disorder
What jaw clenching during the day usually looks like, and why it's so easy to miss
Why prevalence numbers come as ranges: bruxism is hard to study, not rare
What a 2001 sleep-lab study found right before sleep bruxism episodes: brain first, then heart, then jaw
Why you can build awareness while you're awake, but not while you're asleep
Signs that may point to daytime clenching, nighttime clenching, or both
A simple one-week log to bring to your dentist

At night, you protect. During the day, you notice.

💬 Try the one-week check-in, then tell us in the comments: day, night, or both?

Noticing isn't diagnosing. If you have jaw soreness, headaches or facial pain, or chipped or worn teeth, see your dentist. If you think you clench or grind at night, talk with your dentist or a sleep specialist.
