Teeth White and Glo was a definitely positive experience. I couldn't see result while in the shop, however when I got home, OMG! If you have crowns or caps on your teeth in front or sides, please beware. The difference in color will show. So, now my natural teeth are slightly whiter than the dental work but its not such a major difference that I am unhappy. Staff is warm and inviting and I would recommend to at least try.
