What does this question mean?
It is a peroxide gel applied to tooth surfaces, so it can lighten some stains but cannot change fillings, crowns, or veneers.
What can you do next?
Read the label, keep gel off the gums, and stop if burning or marked sensitivity develops.
When should you seek dental care?
Seek care before whitening if you have decay, gum disease, exposed roots, cracks, or unexplained pain.
What should you ask the dentist?
Ask about the active ingredient, your gum health, and the effect on existing restorations.
