Must use consistently for several days in a row to see a difference. Then your teeth might be sensitive to over doing it. Fine line.

I bought these for my teenage daughter. She has used 3 of them and her teeth are alrrady noticeable whiter. I'll definitely buy these again.

Best teeth whitening product! The results are wonderful and it has worked both on myself and my husband.

Worked for sometime , After awhile it hurts your teeth only used it once but they whitened quickly .

These are my go to at home whitening strips. They really do work and don't make your teeth too sensitive.

I just recently bought these and after two sessions, I've noticed a huge result and I am loving my teeth!

Love these will continue to purchase more they give a noticeable difference and won't break the bank

Works great! My teeth and very white. Downside is that is can be a little painful if you have sensitive teeth

I found this product to be as good as other versions that cost more and take longer. Great seal. Great results.
