Caused my tooth enamel to weaken
I don't recommend this product.  It instructs you to put on for an hour but I used it for about 30 minutes and when I removed the strips from my teeth, I noticed my tooth enamel looked transparent in the lower area.  It was not like this before and I am going to write to the company in case others had similar reaction.  Buy at your own risk.<br />My dentist said many inexpensive teeth whiteners can cause enamel erosion and does not advise to use it.  Save your $$ and most importantly, your teeth.
