The Sandusky office is very clean, modern and relaxing and Dr Guglielmo does excellent work. She explained the procedure very well, took all of the necessary time to make sure that I was completely numb, and did a very thorough job with the root canal itself. There was no pain involved in the procedure and the following day, after the novicane had worn off, I still had no pain in my tooth. I would recommend Dr. Guglielmo to anyone who needs a root canal.
