Frequently Asked Questions
Got Questions About Teeth Whitening Kit We've Got Answers 🌿
Is the Teeth Whitening Kit Kit safe for sensitive teeth?
How soon will I see results?
Many users notice a visible difference after just 2–3 sessions, with full results typically seen in 7–10 days of consistent daily use.
How long do the results last?
With proper care (like avoiding staining foods and regular oral hygiene), results can last up to 3 months or more. We recommend touch-up sessions every few weeks to maintain brightness.
Can I use it with dental work like crowns or veneers?
Teeth Whitening Kit is safe to use with dental work, but it won’t whiten crowns, veneers, or fillings—only natural teeth. It’s always best to check with your dentist if unsure.
How long should each whitening session last?
Each Teeth Whitening Kit session should last 10 to 15 minutes. For best results, use it once daily until you reach your desired shade, then switch to occasional touch-ups to maintain your bright smile.
