I have been using these for a few months now and I see a huge difference after one use. I have been drinking coffee everyday for the past 5 years and this has helped with the slight stains that have shown up every now and again.

I've been using white strips for years, and they perform the best. They are definitely worth the price. I'll use almost a full box every six months and then refresh with a strip if I've been on a dark soda binge.

Honestly these products literally make your teeth WHITE so white that your smile is beaming. The cons thou are that your teeth will developed a sensitivity to the cold. I haven't bought these again due to that but they really do work well.

Though I wasn't very consistent with these, the times I did use them, I did not see much of a difference in the whiteness of my teeth. I could have been using them wrong but I wish I would have seen more of a difference

This lot was recommended by my dentist and it is so worth it! Although it is a little pricey, it will work!!! My teeth are so white and it gives me such confidence with my smile! So definitely recommend this!

Definitely notice a difference in the color of my teeth, however my teeth are always a little sensitive after for a little bit so I wouldn't recommend if you have sensitive teeth.

These are AMAZING. I had no tooth sensitivity and just used in the morning while getting ready for work. Used almost daily until box was done. Noticed a difference in just a few days.

Really does whiten your teeth! I love these whitening strips because of how well it whitens. Be careful however, using these too much can damage your enamel and make your teeth very sensitive to hot and cold.

Works soo well for a drugstore product! My dental hygienist recommended these instead of spending hundreds on professional whitening. They work!!! They work fast too! I recommend to all my friends when they're looking for a cheap and easy option

I do NOT like these. I've tried these again on and off for years in hopes that it would work for me, and it doesn't. It leaves my teeth super sensitive, definitely not worth the money for me.
