Sparkling white teeth whitening
Whitening can lighten natural tooth color by removing or breaking down stains, but crowns and fillings do not change shade.
The short answer
Whitening works on natural enamel and dentin by reducing stain molecules or lightening intrinsic discoloration. Restorations such as composite fillings, crowns, and veneers keep their original color.
What is the direct answer?
What does this question mean?
The dentist checks enamel, gums, decay, cracks, and existing restorations before choosing custom trays or an in-office peroxide treatment. Brush with fluoride toothpaste and limit tobacco, coffee, tea, and other staining exposures.
What can you do next?
Seek care before whitening if you have tooth pain, untreated decay, gum inflammation, exposed roots, or a cracked tooth. Contact the dentist if whitening causes persistent sensitivity, gum burning, or uneven color.
When should you seek dental care?
Ask whether the discoloration is surface stain or internal tooth color, whether decay or gum disease needs treatment first, and how existing fillings or crowns will look afterward.
What should you ask the dentist?
Natural enamel may lighten; dental restorations do not whiten.
