Dr smile home whitening
Dr Smile home whitening uses peroxide gel in a tray to lighten some natural tooth stains, with results shaped by fit and tooth health.
The short answer
The clinical subject is home bleaching using peroxide gel delivered through a tray. Peroxide can lighten some molecules within natural enamel and dentine, but it cannot change the shade of crowns, veneers, or fillings.

What should be checked before starting home whitening?
Before using it, inspect the teeth and gums for decay, cracks, recession, ulcers, and inflammation. Follow the product directions exactly, keep gel off the gingiva, and stop when sensitivity or soft-tissue irritation appears.
How can you use and clean the whitening tray safely?
Use the recommended gel amount, seat the tray fully, remove visible overflow, and clean the tray after use. Keep the product away from children and do not combine it with another whitening product without professional guidance.
When should a dentist assess a tooth before whitening?
See a dentist before whitening if a tooth is painful, darkening alone, fractured, or heavily restored. Seek prompt care for gum burns, persistent sensitivity, swelling, or signs of infection.
What should you ask about your home whitening plan?
Ask which ingredient and concentration are present, whether the tray fits, how restorations will look afterward, and what examination is needed before home bleaching.
Frequently asked questions
Is home whitening permanent?
No. New stain can build up and natural tooth colour can change, so maintenance depends on diet, hygiene, and the dentist’s plan.
Why are my results uneven?
Different enamel thickness, existing restorations, dehydration, and different stain types can make colour change uneven.
