A Dallas dentist is at the center of a legal storm following the death of an 82-year-old patient who underwent dental implant surgery. According to a lawsuit, the elderly woman, Fredericka Bailey, succumbed to a pulmonary embolism shortly after the procedure. The papers, filed in Dallas County court, hold the dentist, Dr. Andrew Kelsey, and Frontline Dental Implant Specialists, Inc., doing business as G4 by Golpa, responsible for negligence leading to Bailey’s death.
