A judge in Birmingham is considering a lawsuit challenging an Alabama law that bans teeth-whitening services outside of dentist's offices.
A hearing set for Thursday morning will decide whether the case moves forward.
A North Carolina businessman and a Guntersville woman are challenging a law passed in 2011 to ban the sale of teeth-whitening products and services in places like nail salons.
The lawsuit claims teeth whitening is safe. It contends the law provides dentists with an illegal monopoly and subjects business owner to fines and jail for violations.
The Alabama Board of Dental Examiners says teeth-whitening products can cause burns and other problems like sensitive teeth.
The board also says the plaintiff's haven't proven the law is unconstitutional.
A judge is considering whether to dismiss the case.
