As a Coffee & Soda Drinker. I noticed my teeth are getting stained and yellowed. I wasn't happy with my smile, even tough I take care of my teeth very well. So I decided to get teeth whitened with KOR system for two weeks in-home and one in office session. I had an amazing result, however, I also experienced more than a mild sensitivity with the system, which wasn't easy, but I got through it. I started from A3 shade to 0M1! a huge different. Then I waited for two weeks until the color of my teeth settled to get my two front teeth bonded to close the gap between them. I had a wonderful experience with Dr. Camacho. He is one of the best cosmetic dentist doctors and his staff are great and they took care of me and answered all of my questions. I would totally recommend Dr. Camacho to anyone I know. The total cost of the two producers wasn't cheap, but totally worth it. I'm very happy with my new smile.
