I've just been reading about the upcoming Mayweather Pacquiao fight on wikipedia. Apparently Mayweather is going to be wearing a mouth guard that cost more than my car
Mayweather will be wearing a $25,000 mouthguard for the fight, incorporated with diamond dust, gold flakes, and a $100 bill cut-out. The mouthguard is designed and created by Dr. Lee Gause of New York.
Pacquiao's mouthguard is given to him as a gift from Filipino dentist, Dr. Ed Dela Vega of Canoga Park, Los Angeles. Dr. Dela Vega, who has been custom-fitting Pacquiao's mouthguards for the past decade, has put extra layers of polyvinyl acetate (PVA) in the frontal-interior portion of this new guard to give him added protection from blows. The mouthguard has a tie-dye/watercolor inspired design created from the Filipino flag's colors: red, blue, yellow, and white.
