When can Zoom whitening be worthwhile for tooth stains?
Zoom whitening can be worthwhile for faster, more controlled removal of certain tooth stains when your teeth and gums are healthy.
How does the Zoom in-office whitening system work?
Zoom is an in-office whitening system that uses a peroxide-based gel, sometimes with a lamp designed for the treatment setup. The result depends on the original stain, enamel condition, restorations, and how the gel is applied, rather than on the light alone.
What should the dentist examine before whitening treatment?
Have the dentist examine enamel, gum margins, cavities, cracks, and existing restorations before whitening. The clinician may clean surface deposits, protect the gums, apply the gel in stages, and provide custom trays or maintenance advice when appropriate.
When should tooth pain or gum problems delay whitening?
Arrange an examination before whitening if you have tooth pain, exposed root surfaces, bleeding gums, untreated decay, or a dark tooth after an injury. Seek prompt care for swelling or severe pain because whitening will not treat their cause.
What should you ask about stains and restorations?
Ask which stains are causing the colour change, whether any cavities or gum problems need treatment first, and which restorations will not change colour. Ask how sensitivity will be managed and how the result will be maintained.
Frequently asked questions
Does Zoom whitening change crowns?
No. Crowns and other tooth-coloured restorations keep their existing shade, so a dentist should plan colour matching before treatment.
Can whitening cause sensitivity?
Temporary sensitivity can occur because peroxide passes through enamel and dentine toward the pulp; the dentist can adjust the gel, exposure, or schedule.
