Practice Information



We have been serving your complex Endodontic needs since 1994 when Dr. Samuel Kratchman opened our first office in Exton. Today, each of our three offices has four operatories, fully equipped with the latest technological advances in the field. Microscopes, digital radiography, and 3D imaging are all part of our daily practice.

Our five doctors -- Sam Kratchman, Kenneth Lee, Allen Yang, Ameir Eltom and Lindi Orlin -- bring more than 60 years of experience to Chester County, Pennsylvania. They are all graduates of the Endodontics program at The University of Pennsylvania, where they currently hold part-time faculty positions. This creates a professional environment in which everyone is on the same page at the forefront of the academic world, while still each maintaining unique ways to treat patients.

When you visit our practice, you will be welcomed by our caring staff and treated by friendly doctors who are dedicated to patients’ quality of care. We even have soothing background music that provides a stress-free, relaxing and comforting atmosphere. Endodontics is the… root… of what we do. The only thing, in fact. We look forward to welcoming you.

Our Services

Endodontic Treatment

Endodontic treatment is necessary when your tooth’s “pulp” -- the soft tissue that extends from the crown to the root -- becomes inflamed or infected. We fix this painful problem in one or two visits by removing the inflamed or infected pulp, carefully cleaning and shaping the inside of the tooth, then filling and sealing the space.

Endodontic Re-Treatment

Sometimes a tooth that has received Endodontic Treatment fails to heal or the pain continues. Occasionally, the tooth becomes painful or diseased months or even years after successful treatment. If your tooth has failed to heal or has developed new problems, we can give you a second chance at saving your tooth.

Endodontic Surgery

In a few cases, nonsurgical Endodontic treatment alone cannot save the tooth, and your dentist or Endodontist may recommend surgery to treat damaged root surfaces or surrounding bone. There are many surgical procedures that can be performed to save a tooth, and we will help guide you to the best one.

Our Technology

Endodontic digital radiograph

Endodontic treatment provides a predictable method to retain most teeth. The evolution of treatment has been greatly influenced by new technologies, and we have available to us many new devices and methods to make your care comfortable and successful.


However, it is very important to remember that choosing the appropriate instruments and techniques for your treatment is why our years of clinical experience are so important.
