What I used:
Click here to view the product information on Crest's website. I bought these off of Amazon for $30 (compared to $50+ in the drugstore).
The product is the exact same and came with 20 strips that are to be used either once at day for 20 days or twice a day for 10 days. I have not experienced any sensitivity, but this does vary person to person.
I have done the treatments twice a day for a few days and the sensitivity wasn't an issue then either. When you first take them off, the whiteness looks very uneven, but this goes away after a couple of hours.

Tips:
- Floss teeth and make sure the surface of teeth and in between are cleared of food particles right before using the strips
- The instructions say not to brush you teeth right before, so I used a waterpik to clean the surface of my teeth
- Fold whitestrips in half to leave a crease on the strips, this makes is easy to line the strip up with the center of the teeth
- Dry teeth completely with a tissue before applying will ensure that the strips stick securely onto the teeth
- Gently use fingernail to push the strip into the creased of your teeth
- Set a timer on your phone to know when your 30 minutes is up
- These strips are not hard to remove and I usually brush my teeth right after
- I also do not eat or drink anything the first hour because this is when the pores of the enamel are open and can absorb stains
Before and After:
For me, the differences we so slight that they didn't even show up in photos. However, I had yellow spots (stains) on my teeth that I have had the entire time my permanent teeth have been in and those disappeared completely from my teeth. I am definitely pleased with my results and I have seen amazing results with the majority of people. I think if I bought another box I would get the results I am looking for, but I'm not too concerned right not.
