How to Properly Fit a Gum Shield: The Complete Guide

HOW TO PROPERLY FIT A GUM SHIELD

In the world of contact sports, a gum shield is not just a piece of equipment, but a necessity. It's a protective barrier that fits comfortably around your teeth, safeguarding your mouth during intense physical activity. But how do you fit a gum shield? And what are the different methods that some brands use to fit a gum shield? Let's dive into these questions and more.

How to Fit a Gum Shield?

Fitting a gum shield involves a process known as 'boil and bite'. This method allows the gum shield to mold around your upper teeth, ensuring a snug fit. Here's a step-by-step guide:

  1. Boil water in a pot and submerge your gum shield in the boiling water for about 30 seconds. This softens the material, making it pliable.
  2. Carefully remove the gum shield from the hot water using a pair of tongs. Allow it to cool for a few seconds to avoid burning your mouth.
  3. Place the gum shield in your mouth and bite down firmly. Press your tongue against the roof of your mouth to create a tight suction.
  4. While biting down, suck all the air and water out of the gum shield, molding it to your teeth and gums.
  5. Finally, submerge the gum shield in cold water to set the shape.

Remember, the gum shield should fit around your teeth and not touch your gums to avoid discomfort. It should cover all your upper teeth and not push on your gums. If you can close your mouth comfortably with the mouthguard in place, you've achieved a good fit.

What are the Different Methods that Some Brands Use to Fit a Gum Shield?

Different brands have different methods for fitting a gum shield. For instance, the Black Silver White Opro Instant Custom Fit Teeth Mouth Guard offers a custom fit in minutes, providing excellent protection and comfort.


On the other hand, the Shock Doctor 7501 Ultra 2 STC Mouth Guard is known for its superior design and shock absorption. It uses a gel-fit liner that molds to your teeth for a tight, comfortable fit.


The SISU Max 2.4 NextGen Adult Mouthguard uses a unique Diffusix technology that distributes impact forces over a larger area, reducing the risk of dental injury. The slim, custom fit makes it easy to talk, breathe and drink without removing the guard.

How Do You Get a Mouthguard to Fit?

Getting a mouthguard to fit involves a similar process to fitting a gum shield. The 'boil and bite' method is commonly used, but it's important to follow the specific instructions provided by the manufacturer. Some brands, like SafeJawz, offer mouthguards with a remoldable feature, allowing you to repeat the fitting process until you achieve the perfect fit.

Remember, a well-fitted mouthguard should stay securely in place without you needing to clench your teeth. It should be comfortable, allow for easy breathing and speech, and cover all your upper teeth to provide maximum protection.

How should a Gum Shield Fit?

A well-fitted gum shield should feel comfortable in your mouth and not cause any discomfort or difficulty in breathing. It should cover all your upper teeth, extending back to the molars for complete coverage. The fit should be snug, not too tight or too loose. If the gum shield is too tight, it can cause discomfort or even pain. If it's too loose, it won't provide the necessary protection and could easily fall out during contact sports.


The White Blue SafeJawz Nitro Mouth Guard is a great example of a gum shield that offers a comfortable and secure fit. It features a fluid fit technology that allows for multiple fitting attempts until you achieve the perfect fit.

How Long Do You Boil a Mouthguard to Mold It?

The length of time you need to boil a mouthguard to mold it can vary depending on the brand and the specific product. However, most mouthguards require around 30 seconds in boiling water to become pliable enough to mold.


It's crucial to follow the manufacturer's instructions closely when molding your mouthguard. 


Overheating can cause the material to become too soft and lose its shape, while not heating it enough can result in a poor fit.

Why Doesn't My Gum Shield Fit?

There could be several reasons why your gum shield doesn't fit. It could be that the gum shield is the wrong size for your mouth. Most gum shields come in two sizes: adult and youth. Make sure you have chosen the correct size for your mouth.


Another reason could be that the gum shield wasn't molded correctly. If the 'boil and bite' process wasn't done properly, the gum shield might not have molded to the shape of your teeth and gums correctly. In this case, you may need to remold it or consider getting a new one.

Should a Mouthguard Touch Your Gums?

A mouthguard should cover your teeth and gums to provide maximum protection. However, it shouldn't cause any discomfort. If your mouthguard is touching your gums and causing discomfort, it might not be the right fit. You may need to remold it for a better fit or consider getting a custom-fit mouthguard.

Are Gum Shields Uncomfortable?

Gum shields should not be uncomfortable if they are the right fit. A well-fitted gum shield will stay in place without you needing to clench your teeth, and it won't restrict your breathing or speech. If your gum shield is causing discomfort, it might be due to a poor fit or it might not be the right size for your mouth.

What different solutions could be used for soaking a mouth guard?

After each use, it's essential to clean your mouthguard to remove any bacteria or debris. You can soak it in a solution of warm water and mild dish soap. Alternatively, you can use specialized mouthguard cleaning tablets or solutions, such as the Shock Doctor Antibacterial Mouthguard Spray available on Made4Fighters.

How Far Back Should a Gum Shield Go?

A gum shield should cover all your upper teeth, extending back to the molars. This ensures maximum protection for your teeth and gums during contact sports. If your gum shield doesn't extend far enough back, it may not provide adequate protection.

Do Gum Shields Need to Be Fitted?

Yes, gum shields need to be fitted to your mouth to provide effective protection. A poorly fitted gum shield may not stay in place during physical activity, reducing its effectiveness. The 'boil and bite' method is a common way to fit gum shields, but custom-fit options are also available for a more precise fit.

Should a Mouthguard Cover All Teeth?

Yes, a mouthguard should cover all your upper teeth, from the front teeth to the back molars. This ensures maximum protection for your teeth and gums during contact sports.

Why is My Mouthguard Pushing on My Gums?

If your mouthguard is pushing on your gums, it may not be the right fit. A well-fitted mouthguard should cover your teeth and gums without causing discomfort. If your mouthguard is uncomfortable, you may need to remold it or consider getting a new one.

Should I Be Able to Close My Mouth with a Mouthguard?

Yes, you should be able to close your mouth comfortably with a mouthguard in place. If you can't, it may be too bulky or not the right fit. A well-fitted mouthguard will allow you to close your mouth, breathe, and speak comfortably.

In conclusion, fitting a gum shield correctly is crucial for effective protection during contact sports. With the right fit and regular care, your gum shield can provide the protection you need while ensuring comfort and ease of use.
