Is teeth whitening laser

Laser whitening usually means a peroxide whitening gel activated or accelerated by a dental light, rather than a laser changing tooth colour alone.

The gel contains hydrogen peroxide or carbamide peroxide, which breaks down stain molecules in enamel and dentin. The light may warm or activate the gel, but the chemical peroxide reaction does the whitening work.

A dentist first checks for cavities, gum inflammation, exposed roots, fillings, crowns, and intrinsic discoloration. They then protect the gums, apply the selected gel for timed intervals, rinse it away, and assess sensitivity before giving aftercare instructions.

Arrange an examination before whitening if a tooth hurts, has a crack, has a dark single-tooth stain, or reacts sharply to cold. Seek prompt care for a chemical burn, persistent gum whitening or peeling, swelling, or severe pain after treatment.

Ask whether your discoloration is on the enamel surface or inside the tooth, which peroxide product and concentration will be used, how the gums will be protected, and whether existing restorations will match after whitening.
