How does a professional whitening system work?
A professional whitening system uses peroxide gel after a dental examination and protects the gums during application.
What does a clinician-managed whitening system change?
It is a clinician-managed process for lightening natural enamel, not a treatment that changes the shade of crowns, fillings, or veneers.
What happens during preparation for whitening treatment?
The dentist records shade, checks decay and gum inflammation, selects the gel, protects soft tissue, and controls exposure.
When should dental problems be assessed before whitening?
Seek assessment first if you have sensitivity, untreated decay, gum inflammation, cracks, or restorations to match.
Which whitening and shade concerns should you discuss?
Ask which stains will respond, what gel is planned, and how sensitivity and restoration shade will be managed.
