Frequently Asked Questions
How much does in-office cold-light teeth whitening cost?
$169 per session, a fixed price paid online, at a Taikang Bybo Dental clinic in Beijing, Shanghai, Guangzhou or Shenzhen (other cities: ask us first). The session takes about 60 minutes.
Is Opalescence professional teeth whitening safe for enamel?
Generally yes, when a dentist has checked your teeth first. Our cold-light-assisted protocol minimizes sensitivity.
What does the Opalescence cold-light whitening procedure include?
Standard Opalescence protocol: (1) Shade baseline using a professional shade guide, (2) Gingival barrier resin applied to gums, (3) Opalescence gel applied evenly to teeth, (4) Cold-light activation, (5) Multiple cycles, (6) Final shade comparison. All in 60 minutes.
Are the dentists doing the whitening trained on Opalescence specifically?
A dentist at the clinic checks your teeth first and carries out the session.
Will the dentist explain the whitening process in English?
Clinic staff may speak only basic English. Booking is handled in English; an English-speaking companion at the clinic can be added for $100 per half day.
How long does the cold-light whitening session take?
Just 60 minutes total — perfect for tourists with packed itineraries. Includes shade documentation before and after. Same-day appointments are typically available with confirmed booking. Plan to arrive 15 minutes early.
Is teeth whitening suitable for people over 60 or with sensitive teeth?
Generally yes for healthy enamel. The dentist will assess gum recession and sensitivity at intake. Existing crowns/fillings will not whiten — flagged before treatment starts.
How long do the whitening results last?
Results typically last 1-2 years depending on diet and oral hygiene. Avoid coffee, tea, red wine, and tobacco for 48 hours after treatment for best results. Touch-up sessions or take-home kits are available for maintenance.
Can I fit teeth whitening into a short visa-free trip?
Yes. The session takes about 60 minutes. Many nationalities can visit China visa-free for up to 30 days; the 240-hour visa-free transit also works if you arrive from one country and fly on to a third country or region. We recommend booking 48 hours ahead to confirm your time slot.
What should I avoid right after cold-light teeth whitening?
Strict 48-hour rule: avoid coffee, tea, red wine, dark berries, curry, and tobacco — your teeth absorb stains more easily. Cold or very hot foods may cause temporary sensitivity. Normal eating resumes the same day; stick to white/clear drinks for 2 days.
