MEET Katherine Thomson, D.D.S.

With 25 years of experience, Katherine Thomson DDS has a distinguished educational and professional background with significant experience in both general dentistry and Endodontics (root canal therapy). Her initial studies were at the University of California, San Diego (UCSD), where she earned both a Bachelor's and Master's degree in Chemistry.


Dr. Thomson then completed a General Practice Residency at the Veterans Administration Hospital in Long Beach. She practiced as a general dentist in San Diego for over 8 years, providing comprehensive dental care to the local community. Her thirst for knowledge and dedication to her profession led her to specialize in endodontics, a field she trained in at the University of Southern California (USC). Here, she held the title of Chief Resident among 20 colleagues, marking her as a leader and expert in her field. She is also adjunct clinical faculty at USC.


Outside her professional commitments, Dr. Thomson stays actively engaged in her community and volunteers in various local and international organizations. She resides in La Jolla with her husband and two children, where she enjoys a range of outdoor activities like running, hiking, snow skiing and her favorite waterskiing.


She is a proud member of several prestigious organizations, including the American Association of Endodontists, the American Dental Association, the California Dental Association, the San Diego County Dental Society, and the International Association of Dental Traumatology.


Even though her practice now focuses on endodontics, her history as a general dentist enriches her diagnostic skills and practical approach, allowing her to offer more comprehensive care. She prides herself on spending time with each patient to ensure they receive treatment tailored to their needs and personal circumstances.

What is an endodontist? A specialist in saving teeth.

Treatment of Cracked Teeth

Cracked teeth can cause significant discomfort and pose a risk to oral health. At La Jolla Micro Endodontics, we employ state-of-the-art techniques to diagnose and treat cracked teeth. Our aim is to alleviate pain, prevent further damage, and preserve the tooth's integrity, providing you with a healthier, pain-free smile. Our expert team, led by Katherine Thomson DDS, ensures a comprehensive approach, considering the severity and location of the crack, to devise the most effective treatment plan tailored to your individual needs.

Endodontic Surgery

There are instances where non-surgical interventions may fall short of preserving your tooth. In such situations, the doctors here at La Jolla advise a surgical approach. Endodontic surgery carries numerous advantages and empowers the team to tackle a stubborn infection by excising the tip of the tooth root or even a fractured root, if necessary.
