Crown Dental is by far the best dentist I've been to. Dr. T always takes such good care of us. My 4 year old loved seeing Linda again, our visit was so personable, Linda and Dr. T remembered her from her very first visit. Highly recommend Crown Dental Care!

I love coming to this dentist. The staff are always nice and professional. They go above and beyond to make you feel comfortable and try to make the pain of going to the dentist a bit less terrible. I have had many dentists and hated all of them until I came to Crown Dental Care in Germantown. If you’re looking for a dentist, I would highly recommend them!
