What to expect
Professional in-clinic whitening uses a hydrogen peroxide gel activated by a UV lamp. The session takes 60 to 90 minutes. Most patients see a 4 to 8 shade improvement on the Vita scale.
Sensitivity is the most common side effect; it usually resolves within 24 to 48 hours. Foods and drinks that stain (coffee, red wine, curry, smoking) should be avoided for the first 48 hours.
Results last 12 to 24 months depending on diet, oral hygiene, and whether you use a take-home tray kit for periodic touch-ups.
