Frequently Asked Questions

How long does teeth whitening last?
Results typically last 6 months to 2 years, depending on the method used and your habits. Professional treatments last longer than at-home methods. Avoiding staining foods/drinks and good oral hygiene extend results.
Is teeth whitening safe?
Yes, when used as directed. ADA-approved products and professional treatments are safe for most people. Temporary sensitivity is common but usually mild. Consult your dentist if you have concerns.
What causes teeth staining?
Common causes include coffee, tea, red wine, dark berries, smoking, aging, and certain medications. Surface stains respond well to whitening, while intrinsic stains (inside the tooth) may need professional treatment.
Can I whiten dental work like crowns or veneers?
No, whitening products only work on natural teeth. Crowns, veneers, fillings, and bonding won't change color. If you have visible dental work, consult your dentist about replacement options after whitening.
How white can my teeth get?
Results vary based on your natural tooth color and the method used. Most people can expect 2-9 shades whiter. Professional treatments offer the most dramatic results (6-8+ shades), while at-home methods typically achieve 2-5 shades.
