D.,
I started taking my son (now 6) to the dentist at 3. I take him to my dentist, not a pediatric dentist and he does fine. They told me the first visit they would just take a look, show him the "squirt gun", etc. but he did so well, they did a complete exam & cleaning!
I went first and let him watch and he seemed to be at ease after that. Good luck....their dad is right about this--it's time for a visit!
