I was so excited when my packet of Crest Teeth Whitening strips arrived in the post. I have tried many whitening products before but none of them has really given me the results I wanted.
The Crest strips are formulated using ingredients that are safe for your teeth. I found the strips quite easy to use and the product twice a day by sticking both upper and lower strips to my corresponding teeth.
The strips stuck well to my teeth, they did come off a few teeth, however, this is not a problem if you stick them again. I managed to leave them on for just 30 minutes before removing them.
