How Mouthguards Work
With no mouthguard, a blow to the lower face sends shock waves through the skull. A direct impact can fracture the front teeth. However other blows, particularly to the lower jaw, can cause other damage. A blow to the lower jaw can slam the jaws together and the sudden impact of the relatively sharp lower teeth into the back of the upper teeth is like a chisel, causing a fracture of the upper teeth by punching them forwards.
In some cases, the transmitted forces can lead to a fracture of the lower jaw, or will travel through the jaw joint (TMJ) into the base of the skull causing a concussion.
Mouthguards act like a shock absorber, both spreading the force over a larger area and increasing the time for the peak force to occur. Dissipating the energy of the blow over a larger area and longer time reduces its effect and preventing or vastly reducing any injury.
Jaw joint problems can develop for a number of reasons, for example, if you’ve dislocated your jaw in the past, or you’ve recently had several teeth removed, or you grind your teeth together at night. It’s also possible you may have a condition known as TMJD, temporomandibular joint dysfunction, which makes it difficult for the jaw joint to open and close correctly. We may recommend you wear a custom made splint, for instance. This is a plastic cover designed to be worn over the upper or lower teeth, which improves the way that your teeth fit together, helping to alleviate problematic jaw joint symptoms.
