I have only seen this dentist for a cleaning and check up. However, I have extensive TMJ work in my mouth. It was apparent that Dr. Tavernakis was knowledgable about the work that had been done. He limited x-rays at my request and pointed out some problems I should watch for given my history. He did not push for extra work as some dentists have. He was knowledgable about insurance coverage. I was impressed with his thoroughness. I am prone to trust his honesty and judgement based on his answers to my questions.
