If you are a teeth-grinder or jaw-clencher, while awake or asleep, a mouthguard can provide relief from a headache or TMJ jaw pain. The treatment eliminates the intensity of your teeth clenching and so relief from muscular pain comes in just a few days of wearing the mouthguard.
More importantly, if you grind your teeth a guard will protect them from excessive wear and fracturing that can lead to cavities and early tooth loss.
Another purpose of a mouthguard is to protect the teeth during sports. The mouth is the most commonly injured area of the body during contact sports. Having a custom-made mouthguard helps to protect teeth, gums and in many cases, lips and cheeks.
