Fight Dentist is the official dentist and mouth guard for the UFC and WEC. They will have a booth set up at the Expo and will be taking impressions for those that wish to order a mouth guard. While a kit sent in the mail gives a great impression for a mouth guard, they can take an even better one in person. I have a few guards from them and I literally need to pry it out of my mouth because it fits so well. I am sending all of the fighters from my gym over there to get guards done. If you are looking to get a QUALITY guard, this is the place. I think their show price is $175 and its a GREAT investment.
