Worried about a chipped, cracked, or worn tooth from sports or teeth grinding at night? Mouthguards in Winnipeg can help protect your teeth by softening the force of hits and reducing pressure from grinding. They may be helpful during contact sports, activities where you could fall or get hit, or while sleeping if you grind your teeth. However, different mouthguards are made for different needs. The right choice depends on why you need one, the health of your teeth, and how well the mouthguard fits.

Choosing a suitable mouthguard and keeping it properly fitted can help protect the smile while supporting comfort during everyday use.

How Do Mouthguards Protect Teeth?

A mouthguard is a protective cover worn over the teeth. It acts like a cushion to reduce contact between the upper and lower teeth or soften the impact of a hit to the mouth.

Depending on the type, a mouthguard may help:

  • Lower the risk of chipped or broken teeth.
  • Protect the lips, cheeks, and tongue from accidental bites.
  • Reduce pressure caused by teeth grinding.
  • Help protect dental restorations from damage.
  • Provide added protection during contact sports.

Mouthguards do not prevent every dental injury, but they can lower the risk of certain types of damage.

How Do Sports Mouthguards Stop Damage?

Sports-related impacts can happen quickly and may cause significant force to the teeth. A properly fitted mouthguard can help absorb some of that force and reduce direct impact.

Mouthguards near you may be considered for activities such as:

  • Hockey
  • Football
  • Basketball
  • Boxing
  • Martial arts
  • Soccer
  • Wrestling

A mouthguard should fit securely and comfortably so it does not shift easily during activity. A poorly fitting guard may not provide the same level of protection.

How Do Night Guards Stop Damage From Grinding?

Teeth grinding can place repeated pressure on the teeth, especially during sleep. Over time, this pressure may contribute to worn tooth surfaces, small cracks, sensitivity, or damage to dental restorations.

A mouth guard for teeth grinding and sleep apnea is not the same as a standard sports mouthguard. A dental professional should assess the cause of nighttime grinding and determine whether a night guard is suitable.

A night guard may help by:

  • Creating a barrier between the upper and lower teeth
  • Reducing direct tooth-to-tooth contact
  • Helping protect teeth from excessive wear
  • Protecting some dental restorations from grinding forces

Sleep apnea requires separate assessment and treatment. A night guard should not be assumed to treat sleep apnea unless specifically recommended as part of an appropriate care plan.

Who Should Consider a Mouthguard?

A dentist in Winnipeg may recommend a mouthguard based on dental health, lifestyle, and individual risks. A mouthguard may be worth considering when there is a higher chance of tooth impact or repeated grinding.

It may be helpful for:

  • Athletes involved in contact sports
  • People who grind or clench their teeth
  • Individuals with a history of tooth damage from grinding
  • People with certain dental restorations
  • Patients who need additional protection during specific activities

The type of guard should match the reason it is being used.

Why Is a Proper Fit Important?

A mouthguard should stay in place without needing constant adjustment. A poor fit may feel uncomfortable, interfere with speaking, or make it harder to breathe during activity.

A properly fitted guard should:

  • Cover the teeth it is designed to protect
  • Stay securely in position.
  • Feel comfortable during use.
  • Allow normal breathing
  • Be easy to clean and maintain

A dentist near you can assess the mouthguard fit and recommend an option based on the intended use.

How Should a Mouthguard Be Cared For?

Proper care can help keep a mouthguard clean and in good condition. Rinse it after use and clean it according to the care instructions provided.

Replace a mouthguard if it becomes:

  • Cracked or torn
  • Heavily worn
  • Deformed
  • Difficult to keep clean
  • Too small because of changes in a child’s growing mouth

Regular dental visits can also help check whether the mouthguard still fits properly.

Protect Your Smile With the Right Mouthguard!

A well-fitted mouthguard can help protect your teeth during sports and reduce the effects of teeth grinding at night. Choosing the right type of mouthguard can also help improve comfort, fit, and protection. If you play sports or grind your teeth, a dental assessment can help you find out if a mouthguard is right for you.

No. Sports mouthguards help protect teeth from impact, while night guards help reduce damage from teeth grinding or clenching.

Can a mouthguard protect crowns or other dental work?

A well-fitted mouthguard may help protect some dental restorations from impact or grinding. The right type depends on the restoration.
