Sometimes the English language is just downright confusing. Must we have 10 variations of the same word? Is there a difference between “mouth guard” and “gum shield”?

A gum shield is a protective appliance or device that is used to cover the teeth and gums. We hear dentists and hygienists stress the importance of maintaining our teeth and gums in our daily activities to ensure we remain fit to carry them out efficiently.

It’s called a gum shield because it shields the gums, lips, and teeth from the negative effects of teeth grinding or jaw clenching. Gum shields also protect from injury in case of impact (if used in contact sports like wrestling, boxing, baseball, martial arts, gymnastics, softball, handball, hockey, skating, basketball, and football).

what is a gum shield
This device is fixed on the teeth of either the upper or lower jaw, or both. The gum shield, aka mouthguard, pads between the lower and upper teeth. This can also help reduce the risk of concussion, which may arise when the bottom jaw slams into the upper one, rattling the skull and causing a shock.

For these reasons, it’s always recommended that one should wear a properly fitted gum shield –and make sure that it extends to the molars, as it’s even more helpful this way.

It helps prevent tooth loss and/or lip biting too. Do not cut the ends of your mouthguard just to make it look like you have one in during games. If you find gum shields to be very uncomfortable, simply get a custom-made guard fitted to your dental anatomy and request for a thinner version.

As mentioned above, we “the people”, like to make our own language confusing. As a result, the mouthguard is also known by other names; gum guard, gum shield, mouth piece, bite splint, bite plane, mouth protector, night guard, occlusion splint, teeth guard, dental guard, and teeth protector. Some of the names are more commonly used in a medical setting (such as occlusal splint and bite splint).

Mouth guards are worn to protect the teeth and the gums because of susceptible injury from teeth grinding and impact during sports. There exist some differences between gum shields for sports and bite splints for teeth grinding.

There are also several types of gum shields:

1. Boil & bite mouth protectors. These are made from thermoplastic material. One would first place them in hot water to soften them, then submerge them into their teeth, and by use of their finger and tongue, pressure the right-shaped guard around the teeth. These types can be purchased in many sporting good stores.

2. Stock mouth protectors. These are also sold at many sport good stores, but have already undergone preliminary shaping. They’re generally the least expensive type. They come ready-to-wear with no ability to conform to your teeth. Consumers usually complain a lot about this type of mouth guard. The most common complaints are: “too bulky”, “makes talking and breathing a challenge”, and “little can be done to adjust their fit”.
Their use is therefore not recommended by most dentists.

3. Custom-fitted mouth protectors. This type is designed according to an individual based on dentist’s instructions. The dentist first makes an impression of one’s teeth, then a mouth guard is designed according to the impression, using special materials.

This process is time consuming – with more is involved, making the procedure more expensive than any other mouth guard types. But, it provides the most protection and best comfort.

It’s the best mouth guard solution for teeth grinding as the durability is beyond comparable. There are two different machines used to create custom-fitted mouth protectors:
1) Vacuum form, custom-made gum shields. The use of this machine produces single layer mouth protectors. They offer more protection than the boil & bite type.
2) Pressure laminated, Custom-made mouth guards. This type of machine produces a multi-layer material for varying thicknesses and a tighter fit.

Here is more on the different types of sports mouthguards, and here’s another excellent article that explains the different types of night guards for teeth grinding.

Generally, gum shields cover ones upper teeth only, but most dentists will make them for the lower teeth as well.
A properly trained dentist can suggest the best mouth guard for you to to use.

An effective mouth guard should be long-lasting, easy to clean, comfortable, tear-resistant and should not interfere with one’s breathing or speech.

If you grind your teeth at night, a special gum shield type of dental appliance known as the nocturnal bite plate or bite splint may be designed for you to prevent tooth damage.
