What material are gum shield made out of?

Gum shields (also called mouth guards) are typically made from a variety of materials, including:

- Ethylene-vinyl acetate (EVA) is a soft, flexible material that is often used for custom-fit gum shields. It is comfortable to wear and provides good protection from impacts.

- Polyurethane is another soft, flexible material that is also used for custom-fit gum shields. It is more durable than EVA and provides excellent protection from impacts.

- Polypropylene is a hard, rigid material that is often used for stock gum shields. It is less comfortable to wear than EVA or polyurethane, but it provides very good protection from impacts.

- Silicone is a soft, flexible material that is sometimes used for custom-fit gum shields. It is very comfortable to wear, but it does not provide as much protection from impacts as EVA or polyurethane.

The material of a gum shield is an important consideration when choosing one, as it will affect the level of comfort and protection it provides.
