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.
Is laser whitening really performed by a dental laser?
Laser whitening usually means a peroxide whitening gel activated or accelerated by a dental light, rather than a laser changing tooth colour alone.
How does peroxide gel work during light-assisted whitening?
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.
What should a dentist check before light-assisted whitening?
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.
When should tooth symptoms be assessed before whitening?
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.
What should you ask about light-assisted whitening?
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.
Frequently asked questions
Does a laser whiten fillings?
No. Whitening changes natural tooth structure, while fillings, crowns, and veneers generally keep their existing shade.
Can laser whitening cause sensitivity?
Yes. Temporary sensitivity can occur when peroxide reaches fluid pathways in dentin; the risk depends on the tooth condition and treatment plan.
