What is the direct answer?
Opalescence in-office whitening uses a dentist-controlled peroxide gel after the teeth and gums have been examined.
What does this question mean?
The clinician records the starting shade, isolates the gingiva, applies bleaching gel to natural teeth, and removes it according to the treatment protocol. The gel acts on tooth chromophores, not on fillings, crowns, or veneers.
What can you do next?
Bring a list of medicines and mention sensitivity, cracks, decay, gum recession, or previous whitening. After treatment, follow the clinic’s instructions and use the supplied desensitising product if directed.
When should you seek dental care?
Delay whitening until active decay, leaking restorations, gum inflammation, or exposed-root sensitivity has been evaluated. Contact the clinic if gel causes persistent gum soreness or a tooth develops lingering pain.
What should you ask the dentist?
Ask how the gel will be isolated from your gums, which teeth will be treated, and how existing restorations will look afterward. Ask about expected sensitivity and whether take-home trays are useful for maintenance.
Frequently asked questions
Does in-office whitening use a lamp?
Some protocols use a light and others do not; the active treatment is the professionally selected bleaching gel.
Can I whiten one dark tooth?
A single dark tooth may need an examination for trauma, decay, or pulpal disease before whitening is chosen.
