I had periodontal work done in April 2012. While the results were satisfactory, I would not say they were excellent. I do not consider my results to be excellent because I expected my tooth recession to be completely covered after gum surgery and it is not. I had no complications from the work, but the recovery was longer and more difficult than was described to me. The staff was less professional than expected and during the procedure an assistant exclaimed "gross" at something in my mouth. On the other hand, I can say that I trusted Dr. Hess and I feel that he is an honest periodontist. He will not try to sell you work that you do not need.
