Why will whitening not change fillings or veneers?

Whitening lightens natural tooth structure but does not change the colour of fillings, crowns, veneers, or bonding. A dentist should check for decay, gum inflammation, cracks, and exposed dentine before treatment.

How should you use a prescribed whitening tray?

Have the teeth examined and professionally cleaned if needed, then use the prescribed tray and gel exactly as directed. Record the starting shade in consistent lighting, avoid staining foods while the gel is active, and stop if marked sensitivity or gum irritation develops.

When could uneven or dark teeth need assessment?

Book an assessment if the colour change is uneven, a single tooth is dark, or stains may arise from decay, trauma, fluorosis, or medication. The clinician may compare shades, inspect restorations, and choose whitening, stain removal, or restorative treatment.

What should be checked before whitening sensitive teeth?

Seek dental care before whitening when there is toothache, untreated decay, bleeding gums, exposed roots, or a cracked tooth. Contact the provider if pain persists after stopping the gel.
