What is the direct answer?

Laser bleaching is professional tooth whitening in which peroxide gel is applied to teeth and a light source may be used to activate or heat the system.

What does this question mean?

Peroxide moves through enamel and dentine and oxidizes coloured molecules. Light does not whiten fillings, crowns, veneers, or other restorations, and sensitivity or gum irritation can occur.

What can you do next?

A dentist checks for decay, cracks, gum disease, exposed roots, and mismatched restorations, then protects the gums and applies prescribed gel for controlled intervals.

When should you seek dental care?

Seek review for severe sensitivity, gum burns, uneven colour, or a tooth darkened after trauma. Whitening should wait when active dental disease needs treatment.

What should you ask the dentist?

Ask which peroxide system and light are planned, whether restorations will match, how sensitivity will be managed, and whether another method suits you.
