Zoom bleaching before and after
Zoom tooth bleaching lightens eligible natural teeth, while the visible result depends on stain type, tooth health, and shade matching.
The short answer
Zoom bleaching is an in-clinic whitening procedure using peroxide gel, with a light used according to the product protocol; the result can be assessed by comparing the natural teeth before and after treatment.

How does peroxide affect stains within enamel and dentine?
Peroxide molecules break down some colour compounds within enamel and dentine. Bleaching changes natural tooth structure, but fillings, crowns, veneers, and other ceramics keep their existing colour and may need separate shade planning.
What happens during a supervised Zoom bleaching appointment?
The clinician examines teeth and gums, records a starting shade, isolates the soft tissues, applies the whitening gel in controlled stages, and checks comfort and shade. Treat decay, leaking restorations, gum disease, or exposed roots before whitening.
When should sensitivity or irritation after bleaching be checked?
Ask for dental assessment if you develop persistent sensitivity, gum irritation, uneven colour, or pain after bleaching. Do not use whitening to mask a dark tooth, because internal discoloration may need examination for decay, trauma, or pulpal disease.
What should you ask about stains, restorations and realistic results?
Ask whether the stains are external or internal, which restorations will not change colour, how sensitivity will be managed, what shade is realistic, and whether a custom home tray is appropriate for maintenance.
Frequently asked questions
Does the light bleach the teeth by itself?
The whitening gel is the active chemical component; the light is used within the product protocol.
Why can whitening look uneven?
Existing restorations, internal stains, enamel variation, and different tooth surfaces can respond differently.
