Bests & Worsts Reviews from Amazon

I have tried different whitening products and some cause my gums to be kinda sensitive. I have been eyeballing this product for awhile and looked at reviews closely and I will say I love it! I have used it for going on two weeks and my teeth haven’t been sensitive at all. My teeth are whiter. Yes I know the top pic isthe lighting is different in the top picture and my teeth weren’t as yellow in that picture but I did have some yellow staining as I live off of coffee. The bottom pic is day 4. I flossed, brushed my teeth then used the product and all I did was rinse my mouth out after 20-30 minutes of use. Yes this product is a bit pricey but I enjoy this product and will continue to use it!
