Is a custom night guard worth the cost compared to a drugstore guard?

For most patients with significant bruxism, yes. Custom guards cost $300–$700 versus $20–$80 at a drugstore. A custom guard is made from precise impressions — it fits securely, doesn't shift during sleep, and covers the biting surface completely. OTC guards are generically sized, often too bulky, and slip off during sleep. For mild occasional grinding an OTC guard may be adequate; for chronic grinding with wear or jaw pain, custom is worth the investment.

Will a night guard stop me from grinding my teeth?

No. A night guard does not stop grinding — it protects your teeth and jaw joints from the damage grinding causes. Bruxism is a neuromuscular habit with complex causes (stress, sleep disorders, occlusion). Some patients see reduction with stress management, physical therapy, or treating underlying sleep apnea. Botox injections into the masseter muscle can reduce grinding intensity for some patients.

Can children grind their teeth and do they need a night guard?

Yes, childhood bruxism is common — estimated at 15–40% of children grind their teeth at some point. Most childhood grinding is transient and self-resolving. Night guards are generally not recommended for children under 12 because primary and mixed dentition changes rapidly. For teenagers with permanent teeth and significant wear, a custom guard may be appropriate.

Mouthguards for Teeth Grinding: Custom vs. OTC and What Actually Works

May 12, 2026

What Bruxism Is and Why It Matters

Bruxism is the clinical term for teeth grinding and clenching. It occurs primarily during sleep (sleep bruxism) but also while awake (awake bruxism, often stress-related). Many people with sleep bruxism are unaware of it — the first sign is often a partner noticing the noise, or a dentist observing wear patterns at a routine checkup.

Untreated, chronic bruxism causes:

Enamel wear and flattening of biting surfaces
Tooth fractures and cracked tooth syndrome
Sensitivity from enamel loss
TMJ (temporomandibular joint) pain and jaw soreness
Morning headaches
Accelerated failure of fillings, crowns, and other restorations

Custom vs. OTC Night Guards

Custom Dental Night Guard ($300–$700)

Made from precise impressions or digital scans of your teeth. Fabricated in a dental laboratory from hard acrylic (for heavy grinders) or softer dual-laminate material. Fits precisely, stays in place throughout the night, covers all biting surfaces evenly. Lasts 5–10 years with proper care.

Over-the-Counter Guard ($20–$80)

Boil-and-bite or pre-formed generics. The fit is approximate. Common problems: too bulky, slips off during sleep, may increase jaw muscle activity by not providing even occlusal contact. Acceptable for mild, occasional grinding. Not adequate for significant bruxism.

Online Custom Guards ($100–$200)

Impression kit-by-mail services. Better fit than OTC; lower cost than in-office. Quality control is inconsistent. For complex bite issues or significant wear, in-office fabrication with a dental examination is preferable.

Other Treatments for Bruxism

Stress management: For awake bruxism and stress-driven sleep bruxism — CBT and mindfulness-based stress reduction have evidence behind them.

Physical therapy: For jaw pain and TMJ involvement — a PT specializing in orofacial pain can help with muscle relaxation techniques and jaw exercises.

Sleep apnea treatment: Sleep bruxism is significantly associated with obstructive sleep apnea. Treating sleep apnea often reduces bruxism substantially.

Botox: Injections into the masseter muscle reduce its force and last 3–6 months. Useful for patients with severe grinding not controlled by other means.

Talk to your dentist about bruxism at your next cleaning — they can check for wear patterns you may not notice yourself. Find a dentist near you on The Dentist Ranker.
