Whitening kit from dentist
A dentist-provided whitening kit uses custom trays and prescribed peroxide gel after checking teeth, gums, and restorations.
The short answer
A dentist-provided take-home whitening kit uses custom-made trays and peroxide gel selected after checking the teeth, gums, and existing restorations.
Why do restorations whiten differently from natural teeth?
The gel releases peroxide, which breaks down some stain molecules in natural enamel; crowns, fillings, and veneers do not bleach in the same way.
How should you use and clean your whitening trays?
Follow the prescribed gel amount and wear schedule, clean the trays as instructed, and keep gel away from the gums.
When should whitening side effects be checked?
Contact the dental practice if sensitivity is severe, gum tissue turns white and sore, or pain persists after stopping the gel.
What should you ask about trays, gel and restorations?
Ask which teeth will change shade, how the trays fit, what concentration is prescribed, and how existing restorations will be managed.
