Common Mouthguard Problems and How to Fix Them

Does your mouthguard feel uncomfortable or hard to wear? Mouthguards are essential for protecting your teeth from grinding, clenching, and sports injuries, but discomfort often leads people to discontinue use. If you’ve talked to a dentist in Winnipeg about mouthguard issues, you’re not alone—these concerns are common and usually easy to fix when caught early.

A mouthguard should feel secure, comfortable, and natural to wear. When issues such as tightness, jaw pain, or wear are ignored, they can lead to poor sleep, muscle aches, and tooth damage. Knowing which problems to watch for helps you protect your smile and maintain consistent use.

Is It Normal for a Mouthguard to Feel Tight?

Many patients ask whether it’s normal for a mouthguard to feel tight when they first start wearing one. A slight snug feeling is normal, especially with a new mouthguard. However, it should never feel painful or overly tight.

A mouthguard may feel tight because:

• It was not fitted correctly.
• Teeth have shifted over time.
• The material has changed shape.

If tightness lasts more than a few days or causes soreness, it is a sign the fit needs to be adjusted.

Mouthguard Causes Jaw Pain: What’s Going On?

When a mouthguard causes jaw pain, it often indicates an uneven bite. This can cause the jaw to become strained while sleeping or during sports.

Jaw pain can happen when:

• The mouthguard is too thick.
• The bite surface is not balanced.
• The guard has worn down in certain spots.

Jaw pain should not be ignored. A properly fitted mouthguard helps relax the jaw rather than strain it.

Why Your Mouthguard Feels Loose

A loose mouthguard can move around, fall out, or feel unsafe. This reduces protection and increases discomfort.

Common reasons a mouthguard feels loose include:

• Weight changes or dental work
• Natural tooth movement
• Material wears over time.

If your mouthguard no longer stays in place, it may be time for an adjustment or replacement.

Store-Bought vs Custom Fit

People searching for mouthguards near you often choose store-bought options for convenience. While these can help in some cases, they usually cause more problems than custom-fitted guards.

A better fit usually means fewer problems and better protection.

When to Replace a Dental Mouthguard

Knowing when to replace a dental mouthguard is key to protecting your teeth. Mouthguards do not last forever, even with good care.

You may need a replacement if:

• The guard shows cracks or holes.
• It feels thinner in certain areas.
• It no longer fits comfortably.
• You experience new jaw or tooth pain.

Wearing an old mouthguard can do more harm than good.

FAQs

Is it normal for a new mouthguard to feel uncomfortable?

A new mouthguard may feel snug for the first few days as your mouth adjusts. However, it should not cause pain, sharp pressure, or soreness. If discomfort continues, the fit may need adjustment.

Can a mouthguard cause headaches?

Yes. If a mouthguard does not fit properly, it can strain the jaw muscles and create tension. This tension may lead to headaches, especially in the morning.

How tough does a mouthguard need to be?

Your mouthguard should last between one 1 and 3 years, depending on how you use it. The practical life of the sports item is shortened by constant grinding, use, or visible wear and tear.

Do kids have to change the mouthguards?

Yes. Due to rapid growth, children’s teeth and jaws can change quickly. Regularly replacing your mouthguard ensures comfort and protection.
