Does anyone recommend a good pediatric dentist who participates with Delta Dental??? trying to find one for Joshua, the last guy did not go over well and I ended up pulling him out of the chair and walking out! He had no patience and started hollering at me because i wouldnt let them wrap him up in a straight jacket devise that freaked him the hell out!!! now he is scared to go and i played around long enough!!! Any Advise????? HELP!!!
