  • Came into the dental office scared out of my mind to have a root canal and crown, heard all the horror stories about the pain and did I mention the pain? I had it done and no pain what-so-ever and it looks even better than the original tooth! Thanks Dr. Knox and crew. A great experience that was suppose to be the worst. As bad as I hate to say it “I’ll be back”… Thanks again everyone!!!!

    • Kevin Walker
  • I am delighted with the services here at Knox Dental. All of the employees are personable and very professional.

Dr. Knox is so careful to make sure each visit is beyond acceptable. I applaud him for his excellence and expertise.

  • I have had a fear of dentists since I was a child. My first adult dental experience was with a different dentist who treated dentistry just as a job. Since I have been coming to Dr. Knox, he has proven me wrong each time. I come in scared to death of anticipated pain and each time with his reassurance and patience – It’s a breeze!

Great job from Dr, Knox and his team!!!

  • Another success story at C. David Knox, D.D.S., P.A. When I recently had to have a crown on one of my teeth, as usual C. David Knox, D.D.S provided me with superior service. I am a long time patient of Dr. Knox and Dr. Knox and his entire staff has never let me down. As usual, Dr. Knox made me feel comfortable with the procedure and explained not only the “why” of the procedure, but “how” it would be done. His highly skilled staff make me feel like a valued patient and well you might say “Gave me a Crown fit for a King”. Thank you so much C. David Knox, D.D.S. for raising the bar and setting the standards for others to follow. A patient for life… Victor Whitening

  • I am a lady that loves to smile; so when my teeth fell out of my mouth during class, I had to have it put back in as soon as possible. I stopped by Dr. Knox’s practice, not knowing him but trusting he would be able to make me smile again and that is what he did! The staff was friendly and helpful and assisted Dr. Knox with my treatment. In just one day I was smiling again. I can’t wait to tell everyone I know so they can start a treatment for their teeth that will lead to a great smile!!

  • When I first walked into the office of Dr. Knox, I was any dentist’s worst nightmare. The fear I had of a dentist office for most of my life needed a lot of TLC and a lot of patience. I received over and beyond all my expectations. The professionalism I received from the receptionists, the well trained technicians and the highly skilled Dr. Knox himself, never ceased to amaze me. What I imagined to be a totally unbearable procedure actually turned out to be nearly pain fee and most importantly it left me with a “Winning Smile”. Thank you Dr. Knox.

  • My crown came out wonderful. It fit my gums and matched my teeth very well. Thank you!

  • Dr. Knox and his team of professionals have done an outstanding job for me. I needed to have my lower teeth straightened because I had severe crowding . It was a difficult to clean and floss my teeth. I also had some crowding and misalignment of the upper teeth. I decided to go with Invisalign to address these issues. I have been very pleased with the outcome. The results are amazing. My lower teeth are straightened and properly realigned. My upper teeth are also properly aligned. My dental cleaning treatments are so much easier and less painful. I can brush and floss my teeth without problems. I am in the final stages of refinement and very pleased with the results. I would highly recommend Invisalign and more importantly, Dr. Charles Knox. He is an extraordinary professional and cares about his patients.

  • Dr. Knox has the best staff ever! I have benefited by using Invisalign which was the best product to use on my teeth. I feel great about my smile, I also gained more confidence. The treatment was a great success! Thank you Dr. Knox and Staff.

  • Dr. Knox is the best in the east coast. I have been in the dental field for 20 plus years all over the USA and in 5 countries in Europe. I have known very competent doctors however Dr. Knox is not only charismatic and dedicated but also estute in his dental diagnosis. Two other professionals did not bring to my attention my mouth issues which includes getting crowns. Dr. Knox diagnosed my treatment plan like the “Pro” he is. He is great!
