I had great whitening improvement using the pens for many months. HOWEVER, one day I noticed a translucense in my right front tooth, and a slight wearing at the base. A follow up to my dentist (in a panic!) and he asked me to bring in all my products. He immediately told me to stop using this stuff as the peroxide was eroding my enamel. Damage not reversible but I syopped it from getting worse. Very sad.
