Jaw clicking when chewing or yawning is common — about 25-30% of adults have it. Often harmless. Sometimes a warning sign. The key is whether it’s accompanied by pain, limited movement, or other symptoms. Here’s the Brooklyn dentist breakdown.
Jaw Clicking — Harmless vs Concerning
Harmless if:
- Clicking is occasional (1-2 times per day)
- No pain associated
- Mouth opens fully (3 finger-widths)
- No headaches or ear pain
- Has been present and stable for years
Concerning if:
- Clicking is constant or with every movement
- Pain in jaw, ear, or temple
- Jaw locks open or closed temporarily
- Limited mouth opening (less than 3 fingers)
- Frequent morning headaches
- Recent onset (started in past 6 months)
What Causes Jaw Clicking
- Disc displacement — the cushioning disc in the jaw joint slips slightly out of position; clicks back when you open/close
- Cartilage wear — arthritis-like changes in the joint
- Muscle imbalance — uneven pull from chewing muscles
- Hypermobility — joint moves more than it should
- Past trauma — even old injuries can cause delayed clicking
- Bite misalignment — uneven contact between teeth
The 2-Week Self-Care Trial
Before a dentist visit, try these for 2 weeks:
- Avoid hard, chewy foods — bagels, jerky, chewing gum, hard candy
- Cut food into small pieces — reduce jaw opening
- Apply moist heat to jaw 15-20 min, twice daily
- Avoid wide yawning — push tongue to roof of mouth
- Stop chewing on one side only — alternate sides
- Sleep on your back — side-sleeping pressures jaw
- Massage masseter muscles (sides of jaw) 5 min daily
If clicking persists, becomes painful, or limits movement after 2 weeks, see a dentist.
What the Dentist Will Check
- Range of motion (how wide you can open)
- Joint sounds with stethoscope or palpation
- Muscle tenderness in jaw, temples, neck
- Bite alignment
- Signs of wear on teeth (indicates grinding)
- X-ray or CBCT of the joint if indicated
Treatment for Persistent Clicking
- Custom night guard ($350-500) — most effective for grinding-related clicking
- Physical therapy for jaw and neck
- Bite adjustment if uneven contact identified
- NSAIDs short-term for inflammation
- Stress management for clenchers
Surgery is rarely needed for clicking alone.
FAQ — Jaw Clicking
Is jaw clicking permanent?
Sometimes yes, sometimes no. Acute disc displacement may resolve. Chronic structural changes (arthritis, permanent disc displacement) may persist but can be managed.
Will my jaw stay locked one day?
Possible but uncommon. Acute lock-open or lock-closed episodes can occur in TMJ patients. Usually resolves within hours; rarely requires sedation to manually reduce.
Does coffee or alcohol make it worse?
Indirectly. Both can increase jaw clenching, especially during stress or while sleeping after heavy drinking.
Should I try OTC mouth guard first?
Custom is much better, but OTC guard for 1-2 nights to see if grinding plays a role is reasonable. Don’t use OTC long-term.
Can chewing gum help?
No — chewing gum increases jaw use and often worsens TMJ symptoms. Avoid while symptomatic.
Is jaw clicking related to dental work?
Sometimes. A new crown or filling that’s slightly high can change your bite and trigger TMJ symptoms including clicking. Mention to dentist if symptoms started after dental work.
