What Our Patients Say

The ladies at the front desk quickly and kindly greeted me as I walked in the office. Dr. Norrington had a calmness about him that helped put me at ease when planning for my next appointment. I appreciated how he explained the situation and patiently walked me through our next steps. Great experience overall!

— Ansleigh C

Absolutely the best experience I’ve ever had with a root canal. I was so anxious and everyone made me feel so much better.
The staff was wonderful and Dr. Smithson made sure my comfort was met and he did an incredible job on my tooth. I will definitely go to him again if the need comes up again!

— Marsha B.

The staff is professional and kind. Sarah was amazing! Dr. Hwang did a fantastic job with my root canal and even put in a crown repair/fill so that I wouldn't have to worry about a temp filling while I was out of town. I am not having any pain at all. I highly recommend this practice!

— Marianne H.

Absolutely amazing experience! I had to have a root canal done and it went great and smoothly! The staff was so friendly and even super helpful when my littlest started getting fussy! I appreciate it and the amazing experience! 

—  Scott S.

The staff was wonderful, calming and very communicative which is something I needed due to past bad experiences. And when what we planned turned out not to be the best option they explained what was going on in a clear and understandable ways. Thank you!

— Sandra C.

Totally happy with my experience!  Dr David fit me in this morning to do emergency root canal because I was so uncomfortable.  He is knowledgeable, honest and gentle.  Minimal to no pain.  Excellent doctor! 

—  Kathy S.

Very clean and modern office. The front office staff was incredibly friendly. Dr. Smithson who performed my procedure was awesome and professional as well as the hygienist who assisted. Would definitely recommend anybody who needs a root canal to visit West Atlanta Endodontics.

— Tracey C.

After the first numbing shot, the epinephrine made my heart pound, which then triggered my anxiety. I was embarrassed because I couldn't calm down, but they were so patient with me. I'm very happy with the results and would recommend this office to anyone needing a root canal. 

—   Lori V.

The staff was very cordial and as luck would have it, I was worked into the schedule for a root canal on the same day. I was so appreciative. Dr Norrington did a great job explaining what the procedure would involve. He was very patient and thorough. Once numbed, the procedure was painless. So grateful for this top notch practice.

—  Ken R.

Fantastic overall experience. Dr. Norrington and his staff were extremely professional, courteous, and supportive. This Root Canal was easier and less painful than most cavities I have dealt with in the past. Truly a pain free and easy experience. 

—   Adam P.
