What is the direct answer?
Professional tooth bleaching uses a peroxide gel selected and applied after a dentist checks the teeth, gums, and existing restorations.
What does this question mean?
Bleaching is controlled lightening of natural tooth colour with peroxide gel. The gel acts on chromogenic molecules in enamel and dentin, but it does not recolour fillings, crowns, veneers, or other restorations.
What can you do next?
Book an examination that identifies decay, cracks, recession, restorations, and discoloration type. The dentist may use protective barriers, a custom tray, or an in-office application, then give sensitivity instructions.
When should you seek dental care?
Seek assessment before bleaching for toothache, a cavity, a dark single tooth, gum disease, exposed roots, or unexplained sensitivity. Stop and contact the clinic for persistent pain, ulceration, or marked irritation.
What should you ask the dentist?
Is bleaching the same as cleaning? No; cleaning removes plaque, calculus, and some surface stain, while bleaching changes natural tooth colour. Will a crown become whiter? No; it keeps its manufactured shade.
