Dr. Chang and his staff have been around for years. I saw Dr. Chang after my endo told me I could not save my tooth. Dr. Chang explained the whole process of implant surgery and after a couple of visits, I was in his chair for the surgery. I have to say, the whole process was not as bad as I thought it would be. Dr. Chang was very gentle and patient. He explained the whole process and put me at ease. I am very glad I saw Dr. Chang for the surgery.
