I was nervous going into this. I had never got teeth whitening before and with my sister being a dental hygienist I have heard horror stories. However, once I got there Tamar was so friendly and put me at ease. She was professional, knowledgeable, and had a good sense of humor. The procedure was painless. I experienced no pain or sensitivity at all. Even after drinking ice water I experience no pain or sensitivity. The results were awesome, even though it did take the third treatment to really shine. I went from a 15 to a 1 in three treatments. I love my new white smile and will definitely come back for another round of treatments in 6 months to really lock in my white smile. Definitely a 5 star rating.
