Why professional whitening?
Store-bought strips work slowly and unevenly. In-office whitening uses a professional-strength gel activated by light, so you see results in one short visit, with your gums protected the whole time.
Getting the best results
- Start with a cleaning so the gel reaches clean enamel.
- Avoid coffee, tea, red wine, and tobacco for 48 hours afterward.
- Keep up with regular cleanings to help your results last.
Common questions
How much does whitening cost?
Our 1-hour in-office whitening treatment is $300.
Is whitening safe?
Professional whitening done under a dentist’s supervision is safe for most people. Some patients notice temporary sensitivity, which usually fades within a day or two.
Will whitening work on crowns or fillings?
Whitening works on natural enamel, not on crowns, veneers, or fillings. Dr. Tran can help you plan if you have dental work in your smile.
