Protecting That Winning Smile

If someone in your family is involved in a contact sport, such as football, basketball, baseball, lacrosse, hockey or soccer, protecting his or her smile is a top priority.

While there are many options for athletic mouthguards, countless studies have shown that custom-made mouthguards provide the ultimate protection against tooth or oral-facial injury during the game. And when it comes to custom mouthguards – Underdog comes out on top every time.

The precise fit of the Underdog mouthguard protects athletes from injury, while ensuring top performance as the athletes can breathe and speak comfortably with their mouthguard in place.

Dr. Lirio and his team of dental professionals design and create every Underdog mouthguard, applying the same quality as that used by professional sports organizations, including the NFL, NBA, NCAA, NHL and the U.S. Olympic team.

Dr. Lirio has completed his certification in sports dentistry and is a member of the American Dental Association, Florida Dental Association and the Academy of General Dentistry.

I wanted to share just how awesome my Children's mouth guards are! Dr. Lirio is so great with kids! The Mouth guards click onto their teeth which is amazing because the kids can breathe regularly. They do not drop out of their mouths on the field, they are not biting on them etc. I would highly recommend anyone who plays sports to get a custom mouth guard from Dr. Lirio It's worth it!!!!
