Gum shields are generally safe to wear by everybody. Rarely, some people might be allergic to the acrylic material used to make the gum shield or mouthguard, so always check with your dentist if your gums or other soft tissues appear irritated and swollen after wearing them.

They protect athletes from getting cuts on the tongue, cheeks and lips. They can also prevent tooth fractures and jaw fractures.
