Dental Duty Teeth Whitening Strips - Pack Of 28 - for Upper and Lower Teeth - Best Tooth Whitener Product on the Market.

They work, and they stick better than other strips I've used in the past (looking at you, Crest). They taste pretty not great, so I just kind of try to keep my mouth open and tongue out of they way when I use them, but this is par for the course with any whitening strip. They're effective and you really can't beat the price. Get them!

Didn’t change right away. But my fault for smoking too long. And taking too long to quit. I smoked for 21 years. And it did help my teeth.

No difference from before

Best strips I’ve ever used

Didn't work! Disappointed.

No hype! Buy these for they do what they claim.

Work well.

I like the fact that there is 2 sizes for you to do upper and bottom, I feel like they need to be a tad longer, but it covers a decent amount. They feel like they slip a tad when it says its super strength, but I guess I'll get used to that eventually. It says 14 days for it to be a whiter smile, so hopefully I will have a whiter smile.
