What does this mean?
The chewing muscles work in short bursts and rest through the day. Clenching during sleep holds them contracted for hours. The ache, tightness and fatigue felt in the morning are the result of that sustained contraction.
The timing is what distinguishes it. Worst on waking and easing through the day means muscular origin. Pain that persists all day, worsens with chewing and comes with joint noise points to the joint itself.
The two often travel together: clenching strains the joint, and a strained joint increases muscle tension.
Likely causes
What helps at home?
- A warm compress in the morning relaxes the muscles; it can be used in the evening too
- Notice whether your teeth touch during the day; at rest they should not
- Cut back on gum and hard, chewy food for a while
- The jaw locking open or closed
- Being unable to open the mouth, or a clear reduction in opening
- Pain spreading to the ear, temple or neck
- Rapidly progressing wear or fractures in the teeth
Frequently asked questions
- Does a night guard stop clenching?
- It does not remove the habit. Its job is to spread the force and protect the teeth and joint from damage, which is the most decisive long-term intervention.
- Is stress the only cause?
- Not the only one, but the most commonly reported trigger. Sleep disorders, certain medications and bite discrepancies also play a part.
