“I walked in expecting a Basic cleaning and customary dental experience And I left completely amazed at the quality of service I received from the front desk to the dental work. There was much more I needed to get done than expected, and I felt extremely comfortable entrusting the Team with my care.
Thank you, Dr. Williams, for one of the most thorough, informative, and complete experience I’ve had with a dental professional:”

The front desk people were very friendly, but I just didn’t like especially the dental assistant like he was always in the exam room by my side. It won’t give me breathing room. Then when they were doing the x-rays, I felt like they were not being cautious and hearing my concerns, cause it hurt, especially when they told me to bite down. It was taking over an hour just to be seen by the dentist and then you’re saying that you need to see my x-rays again cause you couldn’t see it clearly which I feel like that was a lie because you wanted to just get extra money from my insurance to get x-rays, which is ridiculous. I really came for a braces consultation and I was just being seen from medical stuff and now you’re telling me to give medical clearance and then giving me all these things that I need to do for my teeth, which is well over $2000 just to get a clearance for my braces to be referred to an orthodontist. SMH so I will never be returning or referring anyone to URBN dental.

After my 2nd appt, Im not sure what to think. Things look promising but from an overall point of view, I think things could have been better with just a little more foresight on both our behalfs.
