What is the direct answer?
In-office dental bleaching uses a peroxide gel, gum protection, and controlled application to lighten natural tooth color during a dental visit.
What does this question mean?
The dentist records the starting shade, isolates the gingiva, and applies a peroxide-based whitening gel to the visible natural teeth. The gel breaks down stain molecules in enamel and dentin; crowns, veneers, fillings, and bonding do not bleach like natural tooth structure.
What can you do next?
A visit usually includes an examination, shade assessment, soft-tissue protection, gel application, timed intervals, rinsing, and a final shade check. Follow the practice’s aftercare advice, use sensitivity products if recommended, and limit strongly colored foods while the teeth are sensitive.
When should you seek dental care?
Book an assessment first if teeth are painful, gums bleed, or restorations are visible in the smile. Contact the practice for persistent sensitivity, gum whitening or soreness, or a result that is uneven because of existing restorations.
What should you ask the dentist?
No. A crown keeps its material color, so the dentist plans whitening and any restoration replacement together.
