Use it daily. It has pretty good results so far and I've been using it for a month. Doesn't taste bad and no sensitivity.

I tried this and saw no difference whatsoever. Expensive for zero results. Did not cause sensitivity which is great but also did not whiten teeth at all.

so far I'm loving this product. I have sensitive teeth and it doesn't bother my teeth at all-I could never use generic whitening strips because they just my teeth so much. I can also already tell that it's working. it's started to remove my coffee stains. no taste, and no scent which I also love.

I was excited to use this product after reading all the reviews but I had no result. It didn't provide any whitening. Disappointed.

Did not see much improvement. I am not sure if it is worth the money, as there are cheaper products.

only applied a small amount on my teeth. Noticed sensitivity right away the next day. My teeth are fine, used other bleaching solution few times in the past, no problem accept this one.

I have purchased the Supersmile Accelerator and the Supersmile Extrawhite triple mint whitening toothpaste twice. I will continue with these products as they make a difference in my smile. Age and daily coffee discolor the teeth but these Supersmile products help and they protect enamel.

ive noticed a light decrease in yellowness but ive also been using it the super smile whitening toothpaste

This particular whitening accelerator works a treat, especially when combined with its Supersmile toothpaste counterpart....(Although I admit I have mixed and matched it with favorite toothpastes in my vast collection, and it also proved pretty darn effective under those conditions...) Unlike other similar products, I find this one does not cause any annoying sensitivity...it just leaves one with a fresh, clean and bright smile!

This helps make my teeth become white which I am loving because I drink a lot of coffee but I love to smile!
