Who says dentists aren't good samaritans? In the month of May, the cost of every whitening procedure (the popular process which creates pearly bright tooth enamel) performed by the Crown Council group of dentists nationwide will be donated to Garth Brooks's Teammates for Kids Foundation, reports The Associated Press. In addition to the network of dentists, the country star, 40, has recruited 400 professional athletes to help fund his organization. Batters and hockey players who sign up pledge to give a monetary donation to Brooks's fund with each hit or goal they make during the season. Ordinary people can also make a donation by using a special credit card linked to Brooks' charity. "Fans (who) are giving money to us know that 100 percent of the donations that you give are going to children and to benefit children and children's charities," Scott Zebedis of Teammates for Kids told the AP. Brooks's charity provides funding to organizations benefiting the health, education and welfare of inner-city children. Brooks' recorded message with more information on the program can be heard at 877-4-SMILES. The Oklahoma native has sold more albums in the United States than any other individual artist. His most recent album was 2001's "Scarecrow," which the singer called "the happiest record I've ever made" in a press release for the album. However, after spending most of the 1990s on tour, Brooks placed his personal life over show business and declined to mount a full-scale concert tour this year, opting to spend more time being a dad to daughters Taylor Mayne Pearl, August Anna and Allie Colleen, born in 1992, 1994 and 1996, respectively.
