Last year I had a lot of work done on my teeth by Dr Adler and all was well. But I recently had a crown done and my experience there was beyond horrible. He had a new assistant who had only worked there a month, who caused more pain than the dentist and had an angry attitude that I have never encountered in a professional environment. Then three days later I developed herpes sores around my mouth on the side they were working on. And I know in my heart of hearts that I did nothing else to get this. So, either him or his assistant did not follow hygenic protocol. I am devastated by this, and want to warn other people of his unsanitary practices.
