Question and answer

Professional teeth whitening process

Professional teeth whitening uses peroxide gel under dental supervision after checking teeth, gums, restorations, and sensitivity risks.

The short answer

Peroxide breaks down stain molecules in natural enamel. Crowns, fillings, veneers, and implants do not bleach, so the dentist checks whether whitening will give an even result.

What happens during the professional whitening process?

The clinician examines the mouth, records a starting shade, protects the gums, and applies measured gel. The gel is removed and the teeth are assessed; custom trays may be planned for further treatment or maintenance.

What should you arrange before starting professional whitening?

Arrange an examination first if you have decay, cracked teeth, gum inflammation, exposed roots, or marked sensitivity. Report severe pain or gum burns after treatment.

When should you ask a dentist about whitening suitability?

Ask which teeth will change shade, how restorations will be managed, and what sensitivity plan is available.

Frequently asked questions

Could another problem look similar?

Yes. Examination distinguishes surface irritation from tooth, gum, appliance, or mucosal disease.

What information should I bring?

Bring a medication list, relevant treatment records, and a note of when the symptom or concern began.
