The short answer
A dentist-provided home whitening kit uses a custom tray or selected tray and a peroxide gel chosen after checking the teeth, gums, restorations, and sensitivity risk. The gel is commonly hydrogen peroxide or carbamide peroxide, which breaks down stain molecules within enamel and dentine. Crowns, fillings, veneers, and other tooth-coloured restorations do not whiten like natural teeth, so shade mismatch must be considered.
What is the direct answer?
What does this question mean?
The gel is commonly hydrogen peroxide or carbamide peroxide, which breaks down stain molecules within enamel and dentine. Crowns, fillings, veneers, and other tooth-coloured restorations do not whiten like natural teeth, so shade mismatch must be considered.
What can you do next?
A dentist examines for decay, cracks, gum disease, exposed roots, and existing restorations before providing instructions. Use only the supplied gel in the prescribed amount and tray time, keep it off the gums, and stop if significant irritation develops.
When should you seek dental care?
Obtain dental advice before whitening if you have untreated decay, gum disease, ulcers, marked sensitivity, pregnancy-related questions, or extensive restorations. Contact the dentist if pain or gum irritation continues after stopping the gel.
What should you ask the dentist?
Which gel concentration and tray design fit my teeth, which restorations will not change colour, and how should sensitivity or gum irritation be managed?
Frequently asked questions
Why use a dentist-made tray?
A well-fitting tray helps place gel against the intended tooth surfaces and reduces overflow onto the gums.
Will a home kit whiten fillings?
No. Tooth-coloured fillings and ceramic restorations generally retain their existing shade, so the dentist should plan for colour matching.
