How To Fit A Mouthguard?

Mouthguard Fitting Guide

Mouthguards are one of the most important pieces of protective equipment an athlete can have. According to the American Dental Association, a properly fitted mouthguard should be part of every athlete's gear, regardless if their sport involves body contact or not. Properly fitting your guard against your teeth makes wearing one more comfortable and increases its protective abilities as well as your athletic performance.

For general instructions on how to size your mouth guard, please follow the steps below

You will need:

• 1 pot with water 
• 1 cup of ice water
• 1 mirror
• 1 timer
• 1 slotted plastic spoon

Step 1:

Fill a pot with 3 inches of water and bring the water to a boil.

Step 2:

Remove the boiling water from the heat source and let the water cool for 30 seconds.

Step 3:

Submerge the mouthguard with the inner liner facing down in the water for 20-30 seconds until the mouthguard walls begin to deform. (See pdf attachements above, for the exact timing which will vary depending on the model of mouth guard.)

Step 4:

Remove the mouthguard from the hot water and let cool under cold water for 2 seconds.

Step 5:

Using a mirror, gently insert the mouthguard into your mouth by aligning it with the center line of your front teeth. Once aligned, using your fingers, press down on your molars and proceed to the next step.

Step 6:

Bring your lower jaw forward and lightly bite down on the mouthguard while pushing the front part of the guard against your teeth and up towards your gums.

Step 7:

Continue the process of pressing against the edges of the guard while sucking the air out for 60 seconds.

Step 8:

Remove the moulded mouthguard from your mouth and place it in ice water for 5 minutes. After 5 minutes, try the mouthguard on and make sure it fits tightly around your teeth.
