Whitening pro
Professional tooth whitening uses a peroxide gel under dental supervision to lighten natural tooth colour after an oral examination.
The short answer
Professional tooth whitening is a dental treatment that uses a peroxide gel to lighten stains in natural enamel and dentin after the dentist checks your teeth and gums.
What does professional whitening mean in dental care?
The phrase usually refers to whitening provided in a dental clinic or with a dentist-prescribed home tray, rather than a general toothpaste or cosmetic label.
How does a dentist select a professional whitening method?
A dentist examines your enamel, fillings, crowns, gum margins, and existing shade, then chooses a light-activated or tray-based peroxide method. Follow the planned contact time and report sensitivity, gum burning, or uneven colour instead of adding more gel.
When should dental problems be treated before whitening?
Arrange an examination before whitening if you have untreated decay, cracked enamel, inflamed gums, exposed root surfaces, or pain. Seek prompt care for facial swelling, spontaneous toothache, or a whitening reaction that does not settle after the product is removed.
Which whitening strength and result are realistic for you?
Ask which peroxide formulation and concentration will be used, whether the visible teeth contain restorations, how sensitivity will be managed, and what result is realistic for your starting shade.
Frequently asked questions
Can whitening remove every stain?
No. It works best on many surface and age-related stains, while some medication-related or developmental discolorations need a different plan.
Why can one tooth stay darker?
A tooth with trauma, a large restoration, or internal discoloration may respond differently and may need separate diagnosis.
