Frequently Asked Questions
Common questions about teeth whitening, costs, and what to expect.
How much does professional teeth whitening cost?
In-office whitening typically ranges from $300 to $900+, while custom take-home trays usually cost $200 to $600. Over-the-counter options range from $30 to $150. Prices vary by location, provider, and your specific needs.
What's the difference between in-office and take-home whitening?
In-office whitening uses stronger whitening agents and may include light-acceleration for faster results—usually in one visit. Take-home trays use a gentler formula you apply at home over days or weeks, which can be more comfortable for people with sensitivity.
Does teeth whitening hurt?
Some people experience temporary tooth sensitivity during or after whitening. This is usually mild and goes away within a few days. If you have sensitive teeth, let your provider know—they can often adjust the treatment strength or recommend a gentler approach.
How long do whitening results last?
Results can last from several months to a couple of years, depending on your habits. Coffee, tea, red wine, and smoking can cause faster re-staining. Many people maintain results with periodic touch-ups and good oral hygiene.
Is teeth whitening safe?
Professional teeth whitening, when done under dental supervision, is generally considered safe for most people. The whitening agents used are designed to work on enamel without causing permanent damage. If you have dental work or specific concerns, discuss them with a provider first.
What's Zoom whitening? Is it better than laser whitening?
Zoom is a brand of in-office whitening that uses a special light to accelerate the whitening process. Laser whitening uses different technology but serves a similar purpose. Both are designed for faster in-office results. The 'best' option depends on your sensitivity, goals, and provider recommendations.
Can I get same-day teeth whitening?
Many dental offices offer same-day appointments for in-office whitening, though availability varies. If you need whitening urgently, contact providers directly and mention your timeline. Being flexible with appointment times can improve your chances.
Will whitening work on crowns, veneers, or fillings?
Whitening treatments primarily affect natural tooth enamel and don't change the color of crowns, veneers, or fillings. If you have visible dental work, talk to a provider about options to keep your smile looking consistent.
Is $500 teeth whitening worth it?
It depends on your priorities. If you want faster, more noticeable results with professional guidance, the investment can be worthwhile. If budget is a bigger concern, custom take-home trays offer a middle-ground option. Over-the-counter products are the most affordable but results vary.
How white will my teeth get?
Results depend on your starting shade, the type of staining, and the method used. Most people see noticeable improvement, but the exact outcome varies. A provider can help set realistic expectations based on your specific situation.
Can I whiten my teeth if I have sensitive teeth?
Yes, many people with sensitivity can still whiten their teeth. Options include lower-strength formulas, shorter treatment times, or staged whitening spread across multiple sessions. Let your provider know about sensitivity so they can tailor the approach.
