Pleasurable Experience

I was referred to First Dental Associates by a family friend and have been a patient for more than 5 years now. The team at First Dental makes a visit to the dentist a pleasurable experience. Upon entering the office, I am greeted by Carol at the front desk, who always wears a smile and asks how my family is doing, creating the kind of personal experience that is hard to find these days. The hygienists are always so friendly, professional, and thorough with cleanings. Dr. Sadeghi, also very kind and professional, has completed flawless dental work for me from replacing fillings to administering my Invisalign treatment. The office is impeccably clean and the equipment is all new. If you are looking for a dentist in the Reading area, I highly recommend First Dental Associates.

I am very anxious going to the dentist even for just a cleaning. Doctor Sadeghi is very caring and gentle. She is very understanding of my apprehension. She performs all services at the pace I can handle. I can’t say enough about the team. They’re just fantastic.
