This dentist is horrible. Do not go to Dr. Woelfle. Approximately two and 1/2 years ago I went for a check up at his office when he was located at the Embarcadero Center. As soon as he took my x-rays, he said that I need a root canal. The tooth that he said needed the root canal was not bothering me at all. However, I was foolish and did not get a second opinion. I went through with the procedure and it was an awful experience. I sat through the whole procedure in pain. At one point, tears began to flow because of the pain, however Dr. Woelfle did nothing but stopped for a few minutes and then continued. He said to me that once you start a root canal, you can not stop midway. It was very painful. I never returned to his office after the horrible and frightening experience. The worse part is he doesn't explain anything to you, which makes the patient even more nervous. I regret never getting a second opinion. In this day and age and in the Bay Area, there plenty of other dentists out there who are more informative, gental and offer painless procedures. Avoid Dr. Woelfle!
