FAQs

  1. Will whitening treatments work on crowns, veneers, or fillings? No. Whitening products only affect natural teeth. If you have dental restorations, your dentist can help you explore matching or replacement options for a consistent look.
  2. At what age can someone safely start whitening their teeth? Teeth whitening is generally recommended for patients over 18, once permanent teeth and enamel are fully developed.
  3. Can I whiten my teeth while pregnant or breastfeeding? It’s best to postpone whitening during pregnancy or breastfeeding, as a safety precaution. Your dentist can help maintain your oral health in the meantime.
  4. How can I maintain my whitening results longer? Avoid staining foods (coffee, red wine, dark berries), brush regularly, and consider using a straw for dark drinks. Regular cleanings and touch-up kits help too.
  5. How soon before a special event should I whiten my teeth? For best results, start in-office whitening at least one week before an event, or begin take-home whitening 2–3 weeks in advance to allow for full results and sensitivity management.
