Supersmile professional whitening
Professional whitening uses controlled peroxide on natural teeth, while toothpaste or kits may mainly remove surface stain.
The short answer
Professional whitening uses a peroxide-based dental bleaching system under controlled conditions, while a branded toothpaste or kit may mainly remove surface stain.
How does whitening change the colour of natural teeth?
Whitening changes the color of natural tooth structure through oxidation of colored molecules. It does not change the shade of fillings, crowns, veneers, or other restorations, and the result depends on the starting stain, enamel, dentine, concentration, and contact time.
What should a dentist check before whitening treatment?
A dentist first checks for decay, leaking restorations, gum inflammation, cracks, and sensitivity. They may clean surface deposits, record the shade, protect the gingiva, apply the selected peroxide system, and provide individualized instructions or trays; follow the product directions for any home toothpaste or kit.
When should whitening be delayed for dental assessment?
Arrange an examination before whitening if teeth are painful, translucent, cracked, decayed, or unusually sensitive, or if gums bleed. Ask for review when the result is uneven because restorations and natural teeth may respond differently.
What is causing the tooth discolouration?
Ask whether the discoloration is surface stain, intrinsic tooth color, decay, or a restoration. Ask which peroxide system is being used, how gums are protected, how sensitivity is managed, and whether existing restorations will need color planning.
