What is the direct answer?
GLO in-office whitening uses peroxide gel with a clinician-controlled light and protective gum isolation.
What does this question mean?
The peroxide breaks down stain molecules within enamel and dentin. Crowns, veneers, fillings, and bonding do not whiten, so their shade must be considered before treatment.
What can you do next?
A dentist examines enamel, gums, decay, cracks, restorations, and sensitivity history before selecting gel strength, isolation, cycle time, and any take-home maintenance.
When should you seek dental care?
Seek dental care before whitening if you have untreated decay, gum inflammation, exposed roots, severe sensitivity, or a tooth that has changed colour.
What should you ask the dentist?
Ask which teeth will change shade, how existing restorations will match, and what sensitivity plan will be used.
