Night guards and mouth guards

Are removable dental appliances that protect your teeth and jaw.

– Night guard (occlusal guard): Worn during sleep to prevent damage from clenching or grinding (bruxism) and to ease jaw joint strain/TMJ symptoms.

– Sports mouth guard: Worn during athletic activity to cushion blows and prevent broken or knocked-out teeth. Not designed for grinding.

Why a night guard might help?

– You wake with jaw soreness, headaches, or facial muscle pain.

– Your partner hears grinding at night.

– You notice worn, chipped, or cracked teeth; gumline notches; or increased sensitivity.

– Your dentist sees flattened biting surfaces or enamel wear.

Benefits

– Protects teeth and dental work from fractures and wear.

– Reduces jaw muscle fatigue and TMJ stress.

– May lessen morning headaches and tooth sensitivity.

– Can save money by preventing future repairs.

Types of night guards

– Soft: Cushioned; good for mild grinding, not as durable.

– Hard acrylic: Very durable; best for heavy grinders or TMJ therapy.

– Dual-laminate: Soft inside, hard outside; balances comfort and strength.

– Upper vs. lower: Either can work; your dentist will choose based on your bite and comfort.

Custom vs. over-the-counter

– Custom dental night guards are made from impressions or scans, fit precisely, last longer, and are less bulky—usually the best option.

– Boil-and-bite or stock guards cost less but can be bulky, less stable, and wear faster.

What to expect with a custom guard?

– Quick impressions or a digital scan.

– Fitting and bite adjustment to ensure comfort and proper jaw position.

– A brief adjustment period is normal; persistent soreness should be checked.

Care tips

– Rinse after use; brush gently with a soft toothbrush and non-abrasive soap.

– Avoid hot water and bleach; they warp or degrade material.

– Periodically soak in a denture/retainer cleaner as directed.

– Store dry in a ventilated case; keep away from pets.

– Bring it to checkups so your dentist can evaluate wear and fit.

Replacement

– Typically every 1–3 years, sooner for heavy grinders or if it cracks, warps, or loosens.

Special notes

– Jaw pain or clicking, locking, or limited opening may require a specific therapeutic splint—see your dentist.

– If you have diagnosed or suspected sleep apnea or significant snoring, ask about an oral sleep appliance rather than a standard night guard.
