Zoom day whitening
Zoom in-office whitening uses peroxide gel and a dental light after the teeth and gums are examined and protected.
The short answer
Zoom whitening is an in-office tooth-whitening procedure in which a clinician protects the gums, applies peroxide gel, and follows a timed treatment protocol.
Which peroxide ingredient makes the whitening gel active?
The active ingredient is usually hydrogen peroxide or a peroxide that releases it. The light is used as part of the branded protocol, while the gel carries out the chemical oxidation of stain molecules within enamel and dentine.
What should be examined before starting Zoom whitening?
Before treatment, the clinician examines the teeth, gums, fillings, crowns, and areas of decay because whitening changes natural tooth colour but not restorations. During the appointment, eye and gum protection, gel placement, timed intervals, and post-treatment instructions are used.
When should decay or sensitivity be assessed before treatment?
Arrange an examination before whitening if you have untreated decay, cracked teeth, gum inflammation, or marked sensitivity. Contact the clinic for persistent pain, gum irritation, or an uneven result that may reflect restorations or underlying disease.
What should you ask about results, sensitivity, and aftercare?
Ask which stains are likely to respond, whether existing restorations will mismatch, how sensitivity will be managed, and what aftercare applies. Ask whether a custom take-home tray is useful for maintenance.
Frequently asked questions
Does the Zoom light whiten fillings?
No; fillings, crowns, and veneers retain their material colour while natural teeth may lighten.
Why can whitening cause sensitivity?
Peroxide can travel through enamel and dentine toward the pulp, temporarily stimulating the tooth’s sensory tissues.
