ADA shares condolences following the death of Greg Biffle

Former NASCAR driver and oral health advocate Greg Biffle died along with his wife, daughter, son and 3 other passengers in a December 18, 2025, plane crash in Stateville, N.C.

Biffle, who was 55, raced in the NASCAR Cup Series over 15 seasons between 2002 and 2022, winning 19 races and finishing in the top 10 a total of 175 times. For many of those seasons, 3M served as the primary sponsor of his number 16 car. Starting in 2011 his car also featured sponsorship from the ADA Foundation’s Give Kids A Smile program along with 3M ESPE Dental and Henry Schein Cares.

“Greg Biffle wasn’t only a champion on the racetrack. He was a champion for children’s oral health and a true humanitarian who impacted countless lives. We extend our deepest condolences to the loved ones of the Biffle family and all who lost their lives in this tragic accident,” said ADA President Richard Rosato, D.M.D.

Biffle’s partnership with GKAS extended beyond his car, as GKAS held events in conjunction with NASCAR multiple races to provide oral health education to children. Biffle made appearances at these events and starred in a 2011 public service announcement for GKAS. Additionally, diecast models of the number 16 car featuring the GKAS sponsorship on the hood were created as a GKAS fundraiser. Along with his work with GKAS, Biffle contributed to other charitable endeavors and he was widely praised for his efforts leading disaster relief in western North Carolina following Hurricane Helene in 2024

“When the ADA and ADA Foundation worked with Greg Biffle, he was a new dad learning about the impact of dental disease on children. Because of this personal connection and his generous spirit, he made a true impact on kids and families as he encouraged them to take good care of their oral health,” said Rita M. Cammarata, D.D.S., ADA Foundation Chair and ADA Board of Trustees Member. “Whether filming a dental health public service announcement or signing autographs for the children at Give Kids A Smile® oral health education events, Greg always went the extra mile. The ADA and ADA Foundation will always be grateful to Greg for giving so many kids a reason to smile during our time together.” 

Biffle’s last first place finish in the NASCAR Cup Series was at the Quicken Loans 400 at Michigan International Speedway on June 16, 2013, with the GKAS logo on the hood of his car.

The ADA and ADA Foundation send condolences to Biffle’s family and loved ones and the families and loved ones of the other people killed in the December 18 crash.
