There is controversy across the United States about the practice of equine dentistry by lay persons versus licensed veterinarians. On Marcy 4, the Oklahoma House passed Bill 3202, which would allow lay equine dentists to practice if they have at least 80 hours of training from recognized schools, pay a $200 certification fee to the state, and gain four hours of continuing education to renew the certificate.

Currently if a non-veterinarian practices equine dentistry in Oklahoma the person can be charged with a misdemeanor.

Under the new law the state veterinary board ill certify equine lay dentists and the Agriculture Department will be in charge of investigating problems.

The bill also covers the controversial use of sedatives, stating if prescription drugs are required for the dental procedure (i.e., sedatives), the horse owner or lay dentist must purchase the drugs from a licensed veterinarian
