Step-by-Step Guide: How to Mold a Mouthguard

Posted on August 28, 2024 in Healthy Living

Mouthguards are essential for protecting your teeth during sports and other activities where there’s a risk of impact to the face. Custom-fitting your mouthguard ensures it provides the best protection and comfort.

Learn when to use a mouthguard, the different types of mouthguards, and a step-by-step guide on how to mold a mouthguard correctly.

When to use a mouthguard 

Mouthguards should be used for contact sports and activities, even if they aren’t required. Football, hockey, lacrosse, martial arts, boxing, and rugby are all sports with a high risk of impact and collisions. Mouthguards should always be worn when participating in these activities.

The American Dental Association (ADA) recommends mouthguards for other sports including baseball, soccer, skateboarding, skiing, bicycling, gymnastics, and more.

Types of mouthguards

Before you start molding, make sure you have the correct type of mouthguard. There are three main types:

• Ready-made or stock mouthguards: Because they were created to be used without customization and their fit cannot be adjusted, these mouthguards are less effective than custom-fit options.
• Mouth-formed mouthguard: Also known as boil-and-bite mouthguards, these mouthguards are available at sporting goods stores and can be molded to fit an individual's mouth.
• Custom-made mouthguards: These mouthguards are made by dentists using a mold of your teeth. While they’re the most expensive option, they’re designed to fit perfectly in your mouth and offer the highest level of comfort available.

How to mold a mouthguard

Follow the steps below to mold a boil-and-bite mouthguard. 

Note: The steps below are general guidelines. Always follow the instructions that come with your mouthguard to ensure a correct fit.

1. Check the initial fit
   1. Start by placing the mouthguard in your mouth and biting down to see how it fits. It should cover all your upper teeth. If it’s too big, use sharp scissors to trim the ends.
   2. Pro tip: Trim the ends gradually and ensure both sides are even in length.
2. Boil water
   1. Boil water in a pot on the stove over medium-high heat. Make sure the water level is high enough to fully submerge the mouthguard.
3. Soften the mouthguard
   1. Using a slotted spoon or similar utensil, slowly lower the mouthguard into the boiling water, ensuring it doesn’t touch the bottom or sides of the pot.
   2. Keep in the water until the manufacturer’s specified time is reached.
4. Cool the mouthguard
   1. Remove the mouthguard from the boiling water and let it cool on a clean towel for 20 seconds. You can also dip it in cold water briefly to remove excess boiling water.

5. Mold the mouthguard
   1. Once slightly cooled, place the mouthguard in your mouth and press it against your teeth.
   2. Use your fingers to shape the sides, and gently bite down to shape it to your teeth.
   3. Suck on the mouthguard to ensure a tight fit.
   4. Pro tip: You have about 30 seconds to mold the mouthguard before it cools down too much to shape properly.

6. Set the shape
   1. Place the molded mouthguard in cold water for 30 seconds to lock the shape in place.

7. Put to use
   1. Your mouthguard is now ready to use. If it doesn’t fit correctly, you can repeat the molding process.

Make sure you store your mouthguard in a dry, ventilated container to prevent bacteria build-up.

Don’t forget to pack your mouthguard

Using a mouthguard can significantly reduce the risk of dental and facial injuries. Whether you are engaging in sports, recreational activities, or have specific dental needs, investing in a quality mouthguard is a wise decision for maintaining your oral health and safety. Always consult with your dentist to determine the best type of mouthguard for your needs.
