He uses oral sedation in liquid form that tastes horrible and doesn't really work well either. His treatment is outdated and his restorative work lacks in artistry. He waits and watches decayed teeth to get worse. My 3 year old had two cavities that I knew about, and he said it was nothing. I went to a relative who was also a dentist and he immediately provided the treatment, and said they were very big. I would not recommend Dr. Weiss
