Smile direct club premium teeth whitening kit
A home whitening kit uses peroxide gel in trays to lighten natural teeth, but it cannot whiten fillings, crowns, or veneers.
The short answer
A home whitening kit uses peroxide gel in trays to lighten natural teeth, but it cannot whiten fillings, crowns, or veneers. The fit of the tray, gel contact, starting tooth color, and presence of decay or gum disease affect the result.
What is the direct answer?
What does this question mean?
The tray holds whitening gel against enamel while peroxide breaks down colored molecules in enamel and dentin. A dental check matters because cavities, cracks, exposed roots, and gum inflammation can make whitening painful or inappropriate.
What can you do next?
Follow the kit instructions for gel amount and wear time, keep gel off the gums, and clean the tray after use. Pause for sharp sensitivity or gum irritation and arrange an examination if symptoms continue.
When should you seek dental care?
Seek care for toothache, a dark single tooth, persistent sensitivity, or a gum burn. A dentist can identify decay or internal discoloration and explain why a restoration may not match after natural teeth are lightened.
What should you ask the dentist?
Ask whether your teeth and gums are suitable, whether the tray fits without covering the gums, and how existing restorations will look afterward. Ask about alternatives if you need treatment for a dark or damaged tooth.
Frequently asked questions
Can I whiten teeth with fillings?
You may have natural teeth whitened if a dentist finds them suitable, but fillings themselves will keep their original color.
What if the trays make my gums white?
Gel pressure or contact can irritate gum tissue; remove the tray, rinse, and seek advice if the tissue remains sore.
