I used Dr. Ortner as a "second opinion", to verify the findings of another endodontist whose recommendation I was not comfortable with. Am I glad I did! Dr. Ortner not only found the RIGHT tooth which needed the root canal but was patient and attentive to all my needs as I am a chicken when it comes to dental procedures. And the whole experience was not more annoying than a big filling! And NO pain afterwards either! Four thumbs up!!!
