M.E.
I took my 3 year old daughter to Drs. Hyde, Bailey, Miller & Cremer in S. Arlington. They were great. I was very impressed from the time I called them to set up an appointment, they were very nice and even set my appointment up with other 3 year olds so she would have someone there her age. They try to take them back by themselves but if they won't go they don't make them, they will let you go back with them. (Which I had to go back with my daughter and I was very impressed that she let them clean her teeth). Everyone there was really nice and makes your child feel very welcome. My daughter had a great first experiance. She asks me all the time when we are going back to the dentist. I would recommend them to anyone.
