Hi,
You could go to Dr. Shiby Thomas at Sarah's Dental Center, near Mercedes Showroom on Salwa Road. She is excellent and very gentle with small children. I take my 7 year old to her and her dental appointments are events that she looks forward to. The contact number for her clinic is 4606059. You could call and fix an appointment as Dr. Shiby's calendars are usually full.

Hope this helps.
