My teeth were sensitive to hot and cold intakes, so Dr. Hernandez gave me this preventive treatment gel, and soon enough, the pain was relieved. Dr. Hernandez is very meticulous with how he treats his patients, and he really knows what he is doing. He follows up the development of his patients, and he makes sure that his clients get the utmost care for their teeth. He is a perfectionist, he maintains a very reliable staff, and uses only state of the art equipment. So to you Dr. Hernandez and the staff of South Florida Dental Arts, congratulations and keep up the good work.
