Crest teeth whitening professional
Professional whitening uses peroxide in fitted trays or a clinic system to lighten natural tooth enamel after an oral examination.
The short answer
Professional whitening uses a peroxide gel in fitted trays or a controlled in-office system to lighten natural tooth enamel.
What does a branded professional whitening kit involve?
A branded professional kit generally means a peroxide product supplied with instructions, sometimes alongside custom trays made from dental impressions or a scan. The gel breaks down stain molecules within enamel and dentin; surface cleaning alone cannot remove internal tooth colour.
What dental checks are needed before professional whitening?
Have the teeth, gums, cavities, cracks, and existing restorations checked before whitening. A dentist can select the gel strength, make trays that keep gel off the gums, record the starting shade, and explain wear time and what to do if sensitivity occurs.
When should pain or gum bleeding delay whitening treatment?
Arrange an examination before whitening if a tooth is painful, has a visible cavity or crack, or the gums bleed easily. Stop the treatment and contact a dental professional if marked gum burning, persistent pain, or a new one-sided toothache develops.
Which causes of tooth colour change can whitening address?
Ask whether the colour change is from surface stain, internal tooth colour, decay, or a restoration, and which teeth will respond. Also ask about the exact peroxide product, tray fit, planned wear schedule, sensitivity plan, and how existing dental work will look afterward.
Frequently asked questions
Can professional whitening remove every stain?
It works best on many external and internal stains in natural teeth, but some medication-related discoloration, developmental colour changes, and restorations need a different plan.
Why can whitening cause zingers?
Peroxide can temporarily move through enamel and dentin toward the pulp, producing short responses to cold or air.
