These made my teeth and gums hurt. I don't think they're safe and I wouldn't suggest more than one use if you have sensitive gums.

I tried this and did not notice much of a difference. It is a possibility I used it wrong. I think it of a affordable at home system.

These are great. They make my teeth a little sensitive but when I use a sensitive toothpaste it solves the problem.

Takes a few times to see any results and if you have sensitive teeth it can hurt slightly. But over time it does work well.

Use these once a month or whenever I feel I need a bit of whitening. As a coffee and tea drinker. I need a whitener and this is the one I like.

I use these regularly. Typically my go to for teeth whitening. The only negative thing is they do not feed my teeth well.

This product is amazing , if you use it 2 times a week I promise you teeth will be so white in a month

Must use a few times to see resulta but you will notice a difference after! I don’t like to keep over 25-30 minutes to prevent sensitivity

I’ve tried different stuff to whiting my teeth nothing works I did try this out still didn’t work I didn’t see any results from these 

While I prefer using whitener from the dentist, this is great and my go to when I go whiten my teeth.
