Question and answer

Fläsh whitening

Fläsh whitening is professional peroxide whitening planned after a dentist checks the teeth, gums, sensitivity, and restorations.

The short answer

Fläsh whitening refers to professional tooth whitening using a peroxide gel selected and applied under dental supervision after the teeth and gums are checked. Professional whitening uses a peroxide compound to enter enamel and break down some stain molecules. The dentist first checks for decay, gum inflammation, cracks, exposed roots, and restorations because whitening changes natural teeth but not fillings, crowns, or veneers.

How does peroxide whitening reduce some tooth stains?

Professional whitening uses a peroxide compound to enter enamel and break down some stain molecules. The dentist first checks for decay, gum inflammation, cracks, exposed roots, and restorations because whitening changes natural teeth but not fillings, crowns, or veneers.

What happens during a professional whitening visit?

The clinical visit may include shade assessment, gum protection, gel application, and a planned exposure period, followed by advice on sensitivity and staining foods. Treatment is adjusted or postponed when disease, pregnancy-related questions, or restorations make the plan unsuitable.

When should you have a dental assessment before whitening?

Seek dental assessment before whitening if you have pain, untreated decay, gum disease, enamel defects, or a single dark tooth. Contact the provider if sensitivity or gum irritation persists after treatment.

What should you ask about the whitening gel used?

Ask which peroxide product and concentration will be used and how the gums are protected. Ask what shade change is realistic for your teeth, how restorations will match, and how sensitivity will be managed.
