Floyd Mayweather is the highest paid athlete currently and can afford the best things money can buy. He loves money so much that his boxing mouthpieces are actually stuffed with real $100 bills.
In order to get these custom made mouth protectors, Floyd pays around $25,000 a piece to an NYC based dentist called Dr Lee Gause.
Apart from real $100 dollar bills, his guards have things like gold flakes and diamonds. 19 years down the line, his smile is still great. Looks like the doctor does a great job.
