What is the direct answer?

What does this question mean?

Both approaches rely on peroxide reaching pigmented molecules in natural enamel and dentin. A light or lamp does not whiten crowns, veneers, or fillings, and neither system corrects decay or gum disease.

What can you do next?

Have the dentist identify the stain type, record a shade, check restorations, and assess sensitivity before selecting the system. Discuss tray fit, application schedule, isolation of the gums, and what happens if sensitivity interrupts treatment.

When should you seek dental care?

Obtain an examination before either system if you have pain, untreated decay, cracked teeth, gum recession, or bleeding. Stop whitening and contact the dental team for persistent pain, gum burns, or swelling.

What should you ask the dentist?

Ask which system matches your stain and sensitivity pattern, how natural teeth will be isolated, and how the final shade will be maintained. Ask whether visible restorations need replacement for a colour match.

Frequently asked questions

Does the light whiten fillings?

No. A light cannot change the colour of composite, porcelain, crowns, or veneers.

Which system causes less sensitivity?

Sensitivity depends on concentration, exposure, tooth condition, and individual response, so the plan must be tailored.
