Night Guard

What Is a Night Guard?

A night guard, also called an occlusal splint or bite guard, is a custom-made dental appliance worn over the teeth during sleep to protect them from the damaging effects of bruxism (teeth grinding and clenching). The night guard creates a protective barrier between the upper and lower teeth, absorbing and distributing the forces of grinding to prevent tooth wear, fractures, and damage to dental restorations.

Night guards are fabricated from durable dental-grade materials and are custom-fitted to each patient’s teeth for a secure, comfortable fit. At Serenity International Dental Clinic in Hanoi, our dentists design custom night guards that provide effective protection while allowing natural, comfortable jaw movement during sleep.

Who Needs a Night Guard?

A custom night guard may be recommended if you:

  • Grind or clench your teeth during sleep (bruxism), often identified by a sleeping partner or your dentist
  • Wake up with jaw pain, headaches, or facial muscle soreness
  • Have worn, flattened, chipped, or fractured teeth with no other explanation
  • Experience tooth sensitivity caused by enamel wear from grinding
  • Have temporomandibular joint (TMJ) pain or dysfunction
  • Have expensive dental work (crowns, bridges, veneers, implants) that needs to be protected from grinding forces
  • Experience tightness or fatigue in the jaw muscles upon waking

Custom Night Guard vs. Store-Bought

While over-the-counter “boil and bite” night guards are available at pharmacies, they are thicker, less comfortable, and less effective than a professionally made custom night guard. Custom night guards are fabricated from precise impressions of your teeth, providing a superior fit that is thinner, more durable, and more comfortable for nightly use. A properly fitted custom guard also maintains correct jaw alignment, which generic guards cannot achieve.

The Process

Examination

Your dentist examines your teeth for signs of bruxism such as wear facets, tooth fractures, or muscle tenderness. Your bite and jaw function are assessed to determine the most appropriate type of night guard.

Impressions

Precise impressions or digital scans of your upper and lower teeth are taken. These records are sent to a dental laboratory where your custom night guard is fabricated.

Fitting

When the night guard is ready, your dentist fits it to your teeth and checks the bite relationship. Minor adjustments are made to ensure a comfortable, secure fit with proper jaw alignment.

Follow-Up

A follow-up appointment may be scheduled to evaluate comfort and make any additional adjustments based on your experience wearing the guard at home.

Benefits of a Custom Night Guard

  • Tooth protection: Prevents wear, chips, and fractures caused by grinding.
  • Pain relief: Reduces jaw pain, headaches, and facial muscle soreness associated with bruxism.
  • Protects dental work: Safeguards crowns, veneers, bridges, and implants from grinding forces.
  • Improved sleep quality: Many patients report sleeping more comfortably once they stop grinding against their own teeth.
  • Custom fit: Precisely molded to your teeth for comfort and security throughout the night.
  • Durable: Professional-grade materials last significantly longer than store-bought alternatives.
  • Maintains jaw alignment: Designed to keep the jaw in a proper, relaxed position.

Aftercare and Maintenance

  • Rinse your night guard with cool water and brush it gently with a soft toothbrush each morning after use.
  • Store the night guard in its ventilated case during the day to allow it to air dry.
  • Avoid exposing the guard to hot water, direct sunlight, or heat sources, which can warp the material.
  • Clean the guard weekly with a denture cleaner or mild soap solution.
  • Bring the night guard to your dental check-ups so your dentist can inspect it for wear and fit.
  • Replace the night guard when it shows signs of significant wear or no longer fits properly, typically every two to five years.

Frequently Asked Questions

How do I know if I grind my teeth at night?

Common signs of nighttime grinding include waking with jaw pain or headaches, tooth sensitivity, visible wear on your teeth, and reports from a sleeping partner who hears grinding sounds. Your dentist can also identify wear patterns during a routine examination.

How long does a custom night guard last?

A professionally made night guard typically lasts two to five years with proper care, depending on the severity of your grinding. Patients with very heavy bruxism may need replacement sooner.

Is it uncomfortable to sleep with a night guard?

Most patients adjust to wearing a custom night guard within one to two weeks. Because it is precisely fitted to your teeth, a custom guard is significantly more comfortable than generic alternatives.

Can a night guard stop me from grinding my teeth?

A night guard does not stop the grinding habit itself, but it protects your teeth and jaw from the damage grinding causes. By cushioning the bite forces and maintaining proper jaw alignment, it also helps reduce associated pain and muscle tension.

Should I wear my night guard every night?

Yes. Bruxism typically occurs unconsciously during sleep, so consistent nightly wear is recommended for ongoing protection. Skipping nights leaves your teeth unprotected during grinding episodes.
