What is the direct answer?
An Opalescence home whitening kit uses peroxide gel in trays, ideally after a dental examination confirms that whitening is appropriate.
What does this question mean?
Peroxide breaks down stain molecules in natural enamel and dentine. Crowns, veneers, and fillings do not bleach like natural teeth, so their existing shade matters.
What can you do next?
A clinician checks for decay, cracks, gum inflammation, exposed roots, and restorations, then provides fitted trays and a wear schedule.
When should you seek dental care?
Use only the prescribed amount, keep gel off the gums, follow the wear time, and stop for significant irritation or sensitivity pending advice.
What should you ask the dentist?
Ask which gel strength and schedule fit your teeth and how existing restorations will look after natural teeth lighten.
