Crest 3d led light

A whitening LED is an added light source used with a peroxide gel, while the gel is the material that contacts and lightens the tooth.

The tray, gel, and LED are separate parts of a home whitening system. Light exposure does not remove calculus or repair decay, and the visible result depends on the starting shade, enamel, restorations, and how the product is used.

Read the product directions and keep gel on the intended tooth surfaces, away from the gums. A dental examination should come before whitening when there is decay, gum inflammation, cracks, exposed root surface, or extensive restorative work.
