My boys have been going to Children's Dental World in Bridgeport since they were two. They do not allow the parents to go back to the exam. They treat the first couple of visits as "fun visits" to acclimate them to the office and getting used to sitting in the chair, opening their mouth, etc. and don't charge insurance (usually because they bring the child back after 5mins or so). My older son had 2 fun visits and was able to have a full exam at his 3rd birthday, while my younger son had only 1 visit and let them do an exam and cleaning at 2-1/2. I had been going to the adult dentist there when I worked in the area. Both of the dentists there ("Dr. Sam" and "Dr. Bubna") are wonderful.
