General questions
Find answers to the most frequently asked questions about our whitening strips.
How do the whitening strips work?
Teethfy strips use a unique mineral salt and coconut oil formula. The sea salt gently exfoliates and lifts surface stains, while the coconut oil protects your enamel. Unlike peroxide-based products that bleach teeth, our strips work by removing stains naturally.
How long until I see results?
Most customers see noticeable whitening after just one 30-minute treatment. For best results, complete all 9 treatments over 9-14 days. Results can last 6-12 months with proper maintenance.
How many treatments are in one pack?
Each pack contains 18 strips for 9 complete treatments (one upper strip + one lower strip per treatment).
How long does each treatment take?
Each treatment takes 30 minutes. Simply apply the strips, go about your day (you can talk, work, or relax while wearing them), then remove and rinse.
Can I use the strips more than once a day?
We recommend one treatment per day for optimal results without overuse. Using more frequently won't speed up results and isn't necessary with our effective formula.
Are the strips reusable?
No, each strip is designed for single use. The whitening gel is consumed during the treatment process.
