Absolutely fantastic. I went in with SEVERE pain in my teeth and after she gave me the lidocaine and nitrous my pain was over. Her equipment is state of the art, and the nitrous mask was the best thing ever. She allows you to control how much nitrous you take in by breathing through your nose (for more) or through your mouth (if you feel dizzy). I am looking forward to having my tooth rebuilt by Dr. Van Horn after a horrendous root canal at a different specialist.
