I am 45 years old and went to Dr. Neeson from the age of 6 - 30. I was amazed when I changed dentists and no longer had a filling or two upon each visit. I recall him checking for cavities and pushing the instrument down into my molar so forcefully that I could hardly keep my jaw in position. I would like to know if others feel this way, too, as I now have a mouth full of mercury fillings that I worry about. I would never recommend Neeson to anyone.
