Teeth Whitening

Teeth whitening works by using bleaching agents, primarily hydrogen peroxide or carbamide peroxide, that penetrate tooth enamel to break down the molecular bonds of colored stains, making them smaller and less concentrated, thus appearing brighter. This chemical process oxidizes the organic chromophores (color compounds) in both the outer enamel and deeper dentin layers, lifting discoloration from food, drinks, and aging. Professional treatments often use higher concentrations with light activation to speed results, while at-home options use lower concentrations in trays or strips for gradual lightening.
