OKLAHOMA CITY (AP) - Gov. Brad Henry has signed legislation that authorizes practitioners of equine dentistry to perform the services.
The measure, passed earlier by the state House and Senate, was among nine bills the governor signed into law on Friday.
The measure amends the Oklahoma Veterinary Practice Act to legalize equine dentistry - also known as horse teeth floating or the grinding down of horse teeth.
Horsemen say they need the services because they can't find veterinarians who perform them. Horse teeth grow continuously and have to be filed down to avoid discomfort.
A law that took effect in November 2008 threatened equine dentists with a felony charge for violating the act.
Oklahoma narcotics investigators had expressed concern that practitioners used controlled and restricted drugs to sedate animals before performing dentistry.
