Teeth grinding, or bruxism, can cause various problems, such as headaches, jaw pain, muscle tightness, and broken teeth. A mouthguard aims to prevent this issue, and there are several types to choose from.

A quick look at 7 of the best mouthguards for grinding teeth

There are two types of bruxism: diurnal bruxism, which involves a person grinding their teeth while awake, and nocturnal bruxism, which refers to teeth grinding during sleep.

A mouthguard is a device a person wears to prevent teeth grinding, often during sleep. Below, we explore the various types of these products and describe when to speak with a dentist.

While a person may not realize that they are grinding their teeth, bruxism can cause:

  • increased wear of the teeth
  • tooth fractures
  • limited ability to open the mouth
  • stiffness and tenderness in the jaw muscles
  • pain in the jaw joint
  • headaches
  • tenderness of the temporal muscles on the sides of the head near the temples
  • earache
  • sleep issues

The American Dental Association explains that there are different types of mouthguards:

  • Custom: A dentist makes these and are typically the most comfortable.
  • Boil and bite: These are often available at sporting goods stores and drugstores. A person softens the guard in boiling water, then bites down, molding the material to the shape of their mouth.
  • Stock: This type of mouthguard is premade and ready to wear, but they may not fit as well.

Medical News Today chooses mouthguards according to the following criteria where possible:

  • Degrees of grinding: Mouthguards that are suitable for mild to severe tooth grinding.
  • Customization: Companies that offer completely custom, semi-custom, and one-size-fits-all mouthguards.
  • Day and night use: Products that are suitable for use while a person is asleep or awake.
  • Price: Products that fit a range of budgets.

Below are seven mouthguards available to purchase online.

Best for customization: Chomper Labs

Chomper Labs offers custom-made mouthguards. First, a person selects the type of material:

  • Hybrid: This aims to protect against moderate-to-heavy grinding.
  • Hard: This is suitable for heavy-to-severe grinding.
  • Retainer: This aims to prevent hard grinding and promote teeth retention.

Next, the company sends a mold kit. The person takes a mold of their teeth, sends it back, and awaits the delivery of their custom mouthguard.

  • Hybrid: This is suitable for moderate grinding.
  • Hard: This is suitable for heavy grinding.
  • Ultra thin: This is suitable for light grinding while a person is awake.

Next, the company sends a mold kit. The person takes a mold of their teeth, sends it back to the company, and receives their custom-made mouthguard in the mail.

A person may visit their dentist with symptoms of teeth grinding, such as jaw pain. Alternatively, a dentist may notice the signs, such as broken teeth, at a regular checkup.

Anyone who has tried a mouthguard and still has pain or any other bruxism symptoms should return to the dentist. It is also important to do so if the guard causes discomfort or other problems.

A dentist may recommend one or more of the following ways to prevent teeth grinding, whether it happens during the day or night.

  • Restorative treatment: This involves addressing damage to teeth.
  • Physical therapy: This may help with muscle pain or stiffness.
  • Psychotherapy: This may be useful if the cause relates to stress.
  • Medication: Antianxiety medication, tranquilizers, or muscle relaxants may help, depending on the cause of the bruxism.

Here are some common questions and answers regarding mouthguards.

How long does it take to get used to a mouthguard?

Some people may find it difficult to sleep with a mouthguard. However, it often becomes more comfortable after several days of use.

If a person experiences pain or discomfort while using a guard, they should discontinue using it.

How can I fall asleep easier with a mouthguard?

It is important to use a mouthguard that fits properly. A person should take the time to research and choose one that does the best job of meeting their needs and the shape of their mouth.

Additionally, using a mouthguard consistently may help someone become used to the guard and fall asleep more easily.

However, if they find that a mouthguard is uncomfortable, they may wish to consult a dentist about getting a custom product.

What is a boil-and-bite mouthguard?

A boil-and-bite mouthguard is a mass-produced mouthguard that a person can customize at home.

The manufacturer will provide instructions on how to fit a boil-and-bite mouthguard. However, a person must generally place the guard in boiling water to soften, then bite down on it so that the guard adapts to the shape of their teeth.

Teeth grinding can lead to pain and other complications, but a mouthguard can help protect against it.

If a mouthguard does not work, a dentist can recommend further approaches to treatment.
