Today more young adults are becoming involved in after school activities. From field hockey, soccer, football, wrestling, basketball these activities are increasing the risk of sport related oral cavity injuries.
It is most important that dental protective devices be fabricated in order to reduce the incidence of injuries.
Many states are trying to mandate the increase  use of mouth guards but have failed in their proposals.
Concerns as to why the mandates have failed  vary from: breathing ability, speech and hygiene of the mouth pieces. I feel that it is most important to fabricate these mouth guards with a licensed dentist , in order to verify fit, proper covering of teeth and protecting gum areas and review care of the mouth guard.
