The lawsuit was filed Thursday in Fayette Circuit Court in Lexington by 71-year-old Lena David of Nicholasville. David claims Dr. W.B. Galbreath told her to try to regurgitate the screwdriver and then sent her for X-rays when that did not work.
Galbreath did not return a message left at his office Friday by The Associated Press.
The lawsuit says that the X-rays showed the screwdriver in David's stomach, and that the dentist discharged her with instructions to "eat a diet high in fiber."
In June 2011, about a month after swallowing the screwdriver, David checked into a hospital with abdominal pain and had to have the screwdriver removed.
