Dr. Keith

About Dr. Alex Keith

Dr. Alex Keith is a general dentist with expertise in both traditional and alternative therapies.

Dr. Keith grew up digging holes, painting, and laying tile for his father’s construction company in the S.F. Bay Area. These early experiences with hands-on work, combined with an interest in biology, led him to his passion in dentistry.


Dr. Keith earned his bachelor’s degree in Biology from CSU Sacramento and went on to obtain his dental training at the prestigious Tufts University School of Dental Medicine in Boston, MA.

During his dental training, Dr. Keith felt there were many aspects of the traditional approach that he could improve upon. This led him to continue his education in alternative therapies.

Alternative dental therapies go by many different names: biological, holistic, or natural dentistry. But what they all have in common is the treatment of the patient as a whole.

Approach to care

Every treatment decision Dr. Keith and his team make is with the intent of caring for the health of the entire child – not just a child’s teeth.

Dr. Keith focuses on prevention and nutrition, using only the most biocompatible materials available. With this unique combination of traditional and alternative therapies, Dr. Keith is able to optimally serve his patients.

Dr. Keith has always loved the California foothills and is overjoyed to be treating children and teens here in Placerville.

He is passionate about contributing to the overall health and wellness of children in the area, as he strongly believes that influencing children at a young age with compassion, empathy, and patience will instill lifelong healthy habits that will keep them smiling throughout life.

​When not playing with kids at work, Dr. Keith spends time with his wife and son. They believe in the importance of a healthy mind, body, and spirit, regularly practicing yoga at his wife’s studio, cooking healthy meals, and enjoying the outdoors as much as possible.
