I highly recommend Dr Eickenhorst and consider him the best endodontist in Austin. I had a root canal done in 2008. I did not feel a thing! Not even the needle. A previous reviewer complained about the time it takes, but root canals are time consuming. I wish they could be done in one appointment, but have been told it is impossible. If I ever need another, he is the one I will call. His friendly personality always put me at ease.
