Contrast PM Whitening: Professional Tooth Whitening Gel for Dentists

Contrastpm is a tooth-whitening gel sold by Spectrum Dental LLC, which is based in Culver City, California. It's manufactured specifically for dentists to give to patients, so consumers can't buy it in stores.

Application

• The patient applies a thin layer of gel to their teeth and then puts a teeth-whitening tray in their mouth. An oxidizing agent called carbamide peroxide is slowly released, which whitens the enamel.

Concentrations

• Contrastpm is made with concentrations of 10 percent and 15 percent carbamide peroxide, which is designed for wearing the trays overnight. It also comes in a gel with 20 percent concentration to be used for one to two hours during the day.

Patient Kits

• Patient kits consist of a touch-up package that has two syringes of gel, a mini kit that contains four gel syringes and a full patient kit that has eight syringes, a tray case and two sheets of tray materials.
