Stock Night Guards
are store bought and available in small, medium and large sizes. They do not fit around the jaws or teeth well.
They are generically shaped and only form a rough fit around the teeth. The result is that when the athlete receives a blow, the night guard is forced back hitting only one or couple of teeth and often breaking them. Additionally, the athlete has to hold the guard by biting it into place. They eventually wear through and need replacement. They are the least retentive, least expensive and bulky. Dental and medical experts recommend that these types of night guards should not be used.
