I am a 40-year old mom - I have a 3-year old who does see a dentist with that policy of "parents by invitation only". I also saw this dentist when I was 3 until age 16. My 14 and 13-year old nieces also see dentists in this practice. None of us have a fear of seeing the dentist. They are very reasonable about children that they cannot calm - only sadists would allow a child to cry for an extended period of time without calling a oarent in. If you'd like to try them they are Dentistry For Kids at about 4800 W. Petersen in Chicago. Good Luck either way.
