Dr Chirco and her staff are so caring. They fully explain your options and costs. I was given several options before we went forward. I had minimal to no pain. I don’t think I had ever had a root canal performed so effortlessly (for me) and painlessly. I was genuinely impressed. Thank you Dr Chirco, Rose, Barb...you are a great team.
