White crest professional effects
Professional whitening lightens natural tooth enamel with peroxide, while results and sensitivity depend on the starting tooth shade and treatment.
The short answer
Professional tooth whitening uses a peroxide gel to oxidize stain molecules in enamel and dentin, making natural teeth appear lighter; temporary sensitivity or gum irritation can occur. It does not change the color of fillings, crowns, veneers, or other restorations.
What is the direct answer?
What does this question mean?
The question refers to the clinical effects of professional whitening, usually with hydrogen peroxide or carbamide peroxide applied under dental supervision. The treatment acts on external and internal tooth discoloration, but its visible effect depends on the type and depth of the stain.
What can you do next?
A dentist first checks for decay, leaking fillings, gum disease, cracks, and restorations before selecting a peroxide concentration and protecting the gums. Follow the prescribed wear or appointment schedule, use a desensitizing toothpaste if advised, and avoid applying household products to the teeth.
When should you seek dental care?
Arrange an examination before whitening if one tooth has darkened, the teeth are painful, or the gums bleed, because these findings can indicate disease rather than simple staining. Contact the dental practice if burning gum pain, marked sensitivity, or an uneven result continues after treatment.
What should you ask the dentist?
Ask which stains are present, whether any cavities or restorations need treatment first, and which peroxide method is appropriate. Also ask how existing crowns or fillings will differ in color and how sensitivity will be managed.
Frequently asked questions
Will whitening remove a crown?
No. A crown keeps its existing ceramic or resin shade, so a dentist plans the color of future restorations around the result.
Why did one tooth not whiten?
A single dark tooth may have internal discoloration from an injured or treated pulp and may need a different assessment or internal whitening approach.
