A mouthguard can protect your teeth and mouth from bruxism (teeth grinding) while sleeping, and from injury when playing sports. They can also provide additional benefits for athletes.

When under stress, the human body responds by clenching muscles, which in turn produces the hormone cortisol. This hormone can cause fatigue, distraction, and inadequate oxygen intake as well as jaw pain. A mouthguard can be customized to correctly position your jaw, eliminating clenching or grinding and enlarging your airway opening. The result: less muscle pain, better oxygenation and breathing, better balance, and the ability to react more swiftly. Under Armour Performance Mouthwear is the brand recommended by Kirkland Cornerstone Dental.

The process of fabricating a mouthguard is relatively simple. Our dental team will take impressions of your teeth and register your bite. This process only takes about 20 minutes, and your mouthguard will be ready in about 10 days.

Hundreds of athletes currently use Under Armour Performance Mouthwear to improve their sports performance or help control bruxism. Mouthguards are recommended for adults and children eight and older who play contact, no-contact, and limited-contact sports, including football, baseball, soccer, tennis, volleyball, and golf.
