Dr. Pauline Karanja

General Dentist

She has always wanted to be a dentist from as far back as she can recall. Having been dental patient herself from a young age as a consequence of indulging in all things sweet, her first experience at the dentist was not a pleasant one, but a subsequent visit to another dentist who was gentle, kind and caring inspired her to want to be just like him, thus her dream was born.

She is a general dentist with a special interest in Root Canal Therapy, and Dental Esthetics. She is gentle and abit of a perfectionist and therefore strives to give her patients the best treatment experience and outcome. 'i believe every patient should actively participate in their own treatment, so I take a 'show and tell' approach which keeps the patient informed and motivated'. She constantly seeks to improve her skills and to keep up with current trends in dentistry.

"Dentistry is not just a job or a career for me, it’s a passion. I thank God I get to do something I enjoy".
Dr. Pauline Karanja
