When a tooth is injured or infected, time and expertise are critical. Our internal team includes Endodontic and Prosthodontic specialists who strive to save your natural teeth wherever possible.

Saving Your Natural Smile

We use Root Canal Treatment, Apicoectomy, and Pulp Therapy to remove infection while preserving tooth structure.

What our patients say about their experience

At Mona Lisa Smile Dental, we believe the best measure of our work is the confidence and comfort of our neighbors. Here is what your Walnut Creek community has to say about our care.

"We traveled out of the way for this office and were not disappointed. Dr. K performed a thorough assessment of my teeth, explaining everything clearly while I followed along on the monitor. The dental hygienist and dental assistant were friendly, and the cleaning was thorough and gentle. We felt welcomed right away and will definitely be back."
Celesti H.
"Mona Lisa Smile has been life-changing for me. I’ve always had a deep fear of dental offices, but this is the first place where I truly felt safe and cared for. The team is warm, patient, and kind, and their phenomenal care helped me overcome my fear. For the first time, I feel calm and confident going to the dentist and genuinely look forward to my visits."
Valerie K.
My family and I love Mona Lisa Smile Dental. The professional staff and excellent care always exceed our expectations. I’ve brought my daughter here since she was four—now 11—and she wouldn’t go anywhere else. The doctor takes his time, pays close attention to detail, and treats every patient with care and expertise. We truly feel like family every time we walk in and highly recommend Mona Lisa Smile for both adults and children.
