Frequently Asked Questions (FAQ)

PRODUCTS & RESULTS
Q: How does Wowhite’s whitening kit work?
A: Our kit uses gentle yet powerful peroxide-free gel (carbamide peroxide or hydrogen peroxide alternatives) activated by an LED light to break down surface and deep-set stains (coffee, wine, smoking) without sensitivity. Results show in 3–7 days with daily use.

Q: Is Wowhite safe for sensitive teeth?
A: Yes! Our formula is pH-balanced and enamel-safe, with added potassium nitrate to reduce sensitivity. For extra care, use our "Gentle Mode" (every other day).

Q: How long do results last?
A: With proper maintenance (avoiding staining foods, using our Whitening Toothpaste), results last 6–12 months. Touch up monthly for best results.

Q: Can I use Wowhite with braces/veneers?
A: Our kit works on natural teeth only. For veneers/crowns, consult your dentist. Avoid use with braces to prevent uneven whitening.

Q: What’s the difference between your kit and drugstore strips?
A: Wowhite’s LED acceleration and higher-concentration gel deliver faster, more even results vs. strips (which often slip and miss spots). No sticky residue!

Q: My gums feel irritated. What should I do?
A: Rinse immediately with water. Reduce usage to 10 minutes/day and avoid gel contact with gums. If irritation persists, stop use and consult a dentist.

AFTERCARE & TIPS
Q: How do I maintain my results?
A: Avoid coffee/tea/wine for 48 hours post-whitening. Drink dark liquids with a straw.

Q: Can I whiten while pregnant/breastfeeding?
A: Consult your doctor first. We recommend waiting due to hormonal sensitivity.

Q: Why didn’t my teeth get Hollywood-white?
A: Teeth have natural undertones (like skin). Our kit lifts stains to reveal your brightest natural shade. For extreme whitening, consult a dentist for professional treatments.
