Dr. Geri Robin was my dentist for many years. She gave me lots of crowns and fillings. I liked her. Then I was due to get yet another cavity filled by her. I went to get a second opinion instead. The dentist told me I had no cavity. The crowns she gave me were well done, according to the other dentist I saw. But I have no way of knowing whether these crowns and fillings were all necessary in the first place. From now on I will always get a second opinion before I let a dentist touch my teeth.
