Dentist Claims Mouth Guards Reduce Concussions

It was one sentence in an overall press release about how mouth guards can protect young student athletes from teeth injuries. Yet, it was also an example of misinformation out there.

A Houston, Texas dentist, Dr, Lynette Crouse, recently communicated in a press release the following: “Dr. Crouse said the mouth guards are ideal for children who participate in sports, but the practice also has created mouth guards for professional athletes. The mouth guards protect patients’ teeth better than over-the-counter mouth guards and reduce the risk of concussions.”

Not true.

As we shared in the blog last month, Matt Gammons, MD, Second Vice President of the American Medical Society for Sports Medicine,  said the idea that “better helmets and mouth guards will prevent concussions” is a myth.

“Unfortunately there is no good scientific evidence that helmets of any type (hard shells, soft-padded or head bands) or mouth guards can prevent or reduce the risk of concussions,” he said. “Hard helmets can reduce the risk of more serious head injuries (bleeding, skull fractures etc.) and should be worn in high risk sports. Mouth guards can prevent dental injuries and should be worn for sports with a high risk of these injuries. Helmet-add ons additionally are not effective in concussion prevention and using these will generally void any warranties associated with the helmet. Risk reduction may be possible in some settings with rule changes (e.g. no hitting from behind in hockey) and behavior changes (e.g. tackling technique in football).”
