What is the direct answer?

What does this question mean?

The bleaching agent can move through enamel and dentine to react with stain molecules. External stains may respond better than discoloration from trauma, medication, fluorosis, or restorations.

What can you do next?

Have the cause of discoloration checked before whitening. A dentist may clean surface deposits, examine for decay and gum problems, protect soft tissues, and select a supervised tray or in-office method when appropriate.

When should you seek dental care?

Arrange an assessment for sensitivity, gum irritation, uneven color, a dark single tooth, cavities, or worn enamel before using a whitening product. Stop a product and seek advice if pain or tissue irritation develops.

What should you ask the dentist?

Ask what type of stain you have and whether existing restorations will change color. Ask which product, exposure schedule, and sensitivity plan fit your teeth and gums.
