Welcome to Chino Valley Endodontics

Welcome to Chino Valley Endodontics, a dental practice dedicated exclusively to endodontic care.  Our expert team, lead by respected endodontic specialists, James Chen, D.D.S., M.S., Selina Chan, D.D.S., and David Berrios, D.D.S., includes an experienced and caring staff.

We offer a full scope of endodontic procedures: root canal therapy, root canal retreatment, apicoectomy.  Root canal treatment is usually all that is needed to save teeth, with injured pulp tissue, from being extracted.

We are a patient-oriented practice devoted to providing specialized endodontic therapy with technical excellence in a gentle and compassionate manner.  We understand that skill and compassion go hand in hand when providing exceptional patient care.

We strive to meet your patients’ expectations and exceed them, with our high standard of excellence, in personalized endodontic care which enables us to provide the highest quality service all patients deserve. That is why we focus on making all patients treatment as comfortable as possible.  Not only are we focused on making their experience pleasant, we also want to ensure that everyone will receive the best possible care and make their endodontic treatment a success.


Advances in endodontics in the past two decades have given endodontists important new tools to save natural dentition.  In the early 1990's, operating microscopes were introduced into endodontic practice.  By providing both intense focused light as well as a high degree of magnification improves visualization of all aspects of the operative field.

The microscope has become an important part of the armamentarium for many endodontists, for the microscope enables endodontists to resolve treatment challenges previously unrecognized or untreatable.

Benefits from the use of a microscope

• Locating hidden canals that have been obstructed by calcifications and reduced in size

• Removing materials such as solid obstruction materials (silver points and carrier-based materials), posts or separated instruments

• Removing canal obstructions

• Assisting in access preparation to avoid unnecessary destruction of mineralized tissue

• Repairing biological and iatrogenic perforations

• Locating cracks and fractures that are neither visible to the naked eye nor palpable with an endodontic explorer

• Facilitating all aspects of endodontic surgery, particularly in root-end resection and placement of retro-filling material
