Intelligent Mouth Guards: New way of preventing secondary concussion brain injuries

by Paul McGurran, Optiflow Digital


Are you a parent whose children play high-impact sports such as rugby? If so you are probably aware of the growing concerns that injuries from secondary concussion can cause teenagers and young adults. The Will Smith directed movie “Concussion” has also helped raise public awareness of the potential dangers of continuing to play on while still concussed. It is estimated that each year approximately 3.8 million concussions occur in USA and that in roughly half of these cases players don’t report it.


Definition: A concussion, also known as a mild traumatic brain injury (MTBI), is caused by a bump, blow, or jolt to either the head or the body that causes the brain to move rapidly inside the skull. A concussion changes how the brain normally functions. Signs and symptoms of concussion include headache, nausea, fatigue, confusion or memory problems, sleep disturbances, or mood changes.


Emergence of Intelligent Mouth Guards Market

There are a number of US start-ups emerging that have been working on developing Intelligent Mouth Guards that seek to address the above problem.


Prevent Biometrics, founded in 2015 and based in Minneapolis, completed a Series A funding round of $2.5 million in 2016. Co-founder and CEO Steve Washburn was previously the CEO of Shock Doctor Mouthguards for 15 years, where he built the brand into the market leader. The accuracy of the Prevent technology has been scientifically validated by the Cleveland Clinic.

“Research has shown that accurate head impact measurements are impossible to achieve without a secure coupling to the skull. This is why we chose to embed our impact monitor in a mouthguard, and develop our technology and intellectual property around this concept,” said CEO Washburn.

How does Prevent Biometrics Work?

Prevent Biometrics ( accurately measures head impacts in real-time on the field of play, giving athletes and coaches the information they need to make sports safer. Embedded in a mouth guard and paired with a mobile app, Prevent’s impact monitor continually monitors the athlete, collecting every head impact received. If an impact force exceeds a pre-set threshold, a red LED immediately illuminates on the mouth guard and an alert is sent to team coaches through the mobile app.

The head impact monitor uses a patented deformable body algorithm to measure the force, direction and location of head impacts in real-time, providing accurate and comprehensive view of athlete head impacts. The company plans to offer two versions of its head impact monitor for athletes ages 11 and older, starting at $199.


In summary, we have discussed the emergence of an intelligent mouth guard start-up. What is innovative about the post-impact feedback to managers and coaching teams is that it is “real-time” and removes any debate about whether a player should stay on or withdraw from the field of play. This will prevent potentially very harmful secondary concussion brain injuries. It will be interesting to plot the progress of Prevent Biometrics in the coming years.
