Laser teeth whitening is a chair-side whitening procedure that uses a peroxide-based gel activated by light energy to accelerate stain breakdown. During treatment, a protective barrier is applied to the gums, and a whitening gel is placed on the surface of the teeth. A blue LED light is then directed at the teeth to activate the gel and speed up the bleaching process.

This method is commonly selected for patients seeking noticeable whitening in a single visit. Treatment time is approximately one hour, and results vary depending on enamel condition, stain depth, and lifestyle habits such as smoking or frequent consumption of coffee, tea, or red wine.

Peroxide-based whitening results typically last between six months and one year. Maintenance treatments are often recommended every three to six months depending on staining patterns and oral hygiene habits.
