How does professional whitening lighten natural teeth?
Professional whitening uses peroxide gel to lighten natural enamel and dentine after an oral-health assessment.
Why will whitening not change restoration colour?
The gel breaks down some stain molecules but does not recolour fillings, crowns, veneers, or bonding.
What should the dentist check before whitening treatment?
A dentist checks decay, cracks, gum inflammation, exposed roots, and sensitivity before selecting in-office or take-home treatment.
When do sensitivity or a dark tooth need dental care?
Seek care for persistent sensitivity, gum irritation, sharp pain, or a single dark tooth.
What should you ask about colour changes and restorations?
Ask what caused the colour change, which method fits, and whether restorations need separate treatment.
