What are Mouthguards?

A mouthguard is also known as a sports guard. It protects the teeth and gums from potential trauma during sports. 

Mouthguards stabilize the jaw while separating the top and bottom rows of teeth from each other. They also absorb or redistribute shock from violent contact that could otherwise result in a bigger injury.

Types of Mouthguards for Sports

There are three types of mouthguards for sports:

  1. Custom made
  2. Boil-and-bite
  3. Stock or ready-made

Each of these vary in cost, comfort, and efficacy.

Custom-made mouthguards are made in a dental office or lab. These are usually the best, but most expensive, option. A dentist gets impressions of your teeth so that the mouthguard fits perfectly in your mouth.

Boil-and-bite mouthguards are self-adapting. You make it yourself by placing it in hot water to become more pliable. Let it cool before placing it in your mouth. The mouthguard adapts to your teeth through the pressure of your bite and manipulation of your tongue, fingers, and lips.

Stock mouthguards are the most easily obtainable type of mouthguard. Most sporting goods stores sell these. However, they usually carry a limited range of sizes.

They’re less comfortable because of their generic design. Additionally, these mouthguards are the least effective because of the potential incompatibility with your teeth and gums.

Why are Mouthguards Important for Sports?

People who engage in contact or limited-contact sports have a high risk of sustaining tooth injuries. A mouthguard significantly reduces this risk.

A mouthguard protects your teeth and surrounding soft tissues by forming a thick layer over them. People who don’t use mouthguards in recreational or competitive sports are almost twice as likely to sustain an orofacial injury.

Best Mouthguards for Sports

The best mouthguard should fit your mouth and other oral structures perfectly. The material should also be FDA (U.S. Food and Drug Administration)-approved.

A good mouthguard should also:

  • Stay in place comfortably and securely
  • Be easy to clean
  • Have high-impact energy absorption

These are some of the best mouthguards for sports:

Taking Care Of a Mouthguard

Avoid using hot water when you’re cleaning your mouthguard. Don’t chew on it or share it with other people.

Rinse the mouthguard with cold water or alcohol-free mouthwash before and after use. You should use dish soap and water with a toothbrush.

Always use a sturdy storage container with holes to promote air circulation. Make sure the mouthguard is completely dry before you close the container.

Bring your mouthguard during dental appointments so the dentist can check its durability and condition. Replace the mouthguard if it:

  • Is loose
  • Has holes or tears
  • Irritates your teeth and/or gums


Mouthguards protect the teeth and surrounding soft tissues from injury during sports. Dentists recommend them for people who participate in contact and limited-contact sports.

The three types of mouthguards include:

  1. Custom
  2. Boil-and-bite
  3. Stock or ready-made

The best option is a custom mouthguard, but these can be expensive. Stock mouthguards are the least expensive, but they’re also the least effective.
