Whitening is one of the most requested cosmetic dental procedures, but results depend on the starting shade and type of discoloration.
How does Philips Zoom whitening work?
Professional whitening uses peroxide-based whitening agents to lighten natural tooth colour. Existing crowns, fillings and veneers do not whiten in the same way as natural enamel.
What matters most?
The dentist first considers oral health, restorations, sensitivity and the cause of discoloration.
- Starting tooth shade
- Type of stain
- Existing veneers or crowns
- Tooth sensitivity
- Gum health
- Post-whitening habits
Why the answer can be different for each patient
Some discoloration responds better than others, and existing restorations may need separate planning if colour matching becomes important.
What should you ask during consultation?
- Are my teeth suitable for whitening?
- Will my fillings match afterward?
- What sensitivity should I expect?
- How should I maintain the result?
Whitening should not be used to mask untreated decay or gum disease.
