1. Will these strips cause sensitivity?
Our PAP+ formula is specifically designed to be peroxide-free, making it a much gentler alternative to traditional strips and ideal for those with sensitive teeth.
2. How long do I wear them?
For the best results, simply apply the strips to your teeth for 30 minutes, then remove and rinse your mouth with clean water.
3. Can I use these if I drink coffee daily?
Yes! These strips are specifically formulated to effectively break down stubborn extrinsic stains caused by coffee, tea, and red wine.
