What Is Teeth Whitening?
Whitening products use peroxide-based chemistry to break down colour-producing molecules within natural tooth tissues. The response varies according to the type and depth of discolouration, concentration and exposure protocol, tooth condition and individual sensitivity. Surface cleaning can remove plaque and external stain but is different from bleaching. Whitening also differs from placing veneers or crowns, because it changes the shade of natural teeth without covering them.
