How to Choose the Right Mouthguards for Teeth Grinding?

Have you ever woken up with a tight, painful jaw? Or has anyone told you that you grind your teeth while sleeping? If so, you might be suffering from bruxism.

Bruxism is an unconscious habit where you grind or clench your teeth that affects between 8% and 31% of people worldwide. Besides jaw pain, it can cause worn teeth, sensitivity, headaches, and sleep problems.

Mouthguards for teeth grinding are the main tool to protect your teeth and reduce discomfort. In this article, you’ll learn what they are, how they work, how to use them properly, and how to choose the best model for you in 2025.

What are mouthguards for teeth grinding?

Also called dental splints or night guards, these devices are designed to cover your teeth while you sleep, creating a barrier between your upper and lower teeth.

Their main function is not to stop bruxism, but to prevent tooth damage by absorbing the grinding forces.

What types of mouthguards exist?

Standard (stock) mouthguards

• • pre-made and ready to use
  • cheapest option but with minimal fit and comfort

Boil-and-bite mouthguards

• • softened in hot water and molded by biting at home
  • better fit than standard, still affordable

Custom mouthguards

• • made to measure by your dentist or with home impression kits
  • offer the best fit, comfort, and effectiveness but are more expensive and take longer to get.

How do mouthguards for teeth grinding work?

They distribute the force of clenching evenly, protecting your teeth and jaw joints. Acting as a soft barrier, they absorb pressure and prevent your upper and lower teeth from grinding together.

Some guards also help relax your chewing muscles, reducing tension in the jaw, neck, and head for a more restful sleep.

What are the benefits of using mouthguards for teeth grinding?

Mouthguards for teeth grinding have many benefits. 

How do mouthguards protect your teeth from damage?

Mouthguards act like shock absorbers between your teeth, preventing:

• tooth fractures
• enamel erosion
• sensitivity caused by constant grinding or clenching

They create a safe barrier that keeps your teeth strong and healthy.

Can mouthguards reduce jaw and facial pain?

Yes, by distributing the pressure from clenching or grinding, mouthguards:

• lower muscle tension in your jaw and face
• relieve TMJ (jaw joint) pain
• reduce the frequency of headaches related to bruxism

You should feel more relaxed and comfortable throughout the day.

Do mouthguards improve sleep quality?

Definitely, by stopping grinding noises and reducing discomfort, many people experience:

• a deeper and more restful sleep
• fewer nighttime awakenings
• better energy and mood during the day

Are mouthguards comfortable?

Yes, with different options, from stock to custom-made, you can find one that:

• fits your bite well
• feels comfortable all night
• encourages you to use it consistently for better results

Do mouthguards help save money in the long run?

Yes they do. A good mouthguard prevents expensive dental treatments caused by:

• severe tooth wear
• cracks or fractures
• TMJ disorders

This means significant savings in dental care over time.

How to use mouthguards for teeth grinding effectively?

Using a mouthguard is easy, but taking care of it is very important. A good cleaning keeps it comfortable, effective, and  longer lasting. 

Here’s how to use and care for it every day:

1. Wear it every night

Wear your mouthguard every night or as your dentist recommends. This routine protects your teeth and keeps your guard working optimally.

2. Make sure it fits just right

• • Boil‑and‑bite mouthguards: heat them and bite down as directed so they mold to your teeth.
  • Custom mouthguards: ensure they fit snugly when first used; if not, consult your dentist.

3. Clean it right after using

• • Rinse it with cool or lukewarm water as soon as you take it out. This will remove saliva and debris.
  • Brush it gently using a soft-bristle brush dedicated only to your mouthguard (don’t use your regular toothbrush). Use mild hand soap, not toothpaste.

Avoid toothpaste to clean your mouthguard; it is too abrasive and can scratch the plastic, causing stains and allowing bacteria to stick and grow over time.

4. Dry it before storing

• • Let it air-dry on a clean towel for 15–30 minutes.
  • Once dry, store it in a ventilated, rigid case away from heat or damp environments.

5. Deep clean weekly or biweekly

There are options like:

• Vinegar + hydrogen peroxide soak: soak in white vinegar for 30 minutes, rinse well, then soak in hydrogen peroxide for another 30 minutes. Rinse again and air-dry completely.

• Denture cleaner tablets: dissolve in water and soak for about 10–15 minutes, then rinse and dry.

Avoid: bleach, mouthwash with alcohol, hot water, or overly long soaks; these can warp or damage the guard.

6. Clean the case, too

Wash your case every few days with mild soap, rinse well, and let it air-dry. A clean guard in a dirty case is useless.

7. Inspect and replace regularly

• Check for cracks, holes, warping, discoloration, or fading fit.
• Replace OTC guards every 3–6 months; custom guards can last a few years with good care.

8. Bring it to dental checkups

Take your mouthguard to dental appointments so your dentist can inspect and deep clean it. This will  catch wear issues early and support your oral health.

A simple routine, like wearing it nightly, rinsing, brushing lightly, air-drying, deep-clean weekly, and with regular inspections, will keep your mouthguard clean, effective, and long-lasting. When in doubt, ask your dentist; they’re your partner in protecting your smile.
