It has been more than three years since the Covid-19 virus entered our lives.  The dental community did an excellent job stepping up to the task of protecting their patients, staff and themselves, during the pandemic, and continue to do so.  Our commitment to your safety is still unwavering.  Infection control has always been a top priority for us at Southern New Hampshire Endodontics.  Our office continues to follow infection control recommendations made by the American Dental Association, the U.S. Centers for Disease Control and Prevention and the Occupational Safety and Health Administration, so our protocols  remain current.  I have worked hard to be sure we have all the recommended and necessary PPE for your care.  There are many more procedures, some of which you may observe and others that are done behind the scenes, all instituted to provide a safe environnment for your care.  We look forward to seeing you and please call us if you have any questions.  --- Dr. Michael Marshall





Our Mission

Endodontic specialist, Dr. Michael Marshall and his experienced team of assistants and office personnel have the goal of providing their patients with an exceptional experience.  When performed carefully endodontics can be accomplished in a very pleasant, comfortable manner and is an effective means of saving a tooth and maintaining the integrity of your natural dentition.    

Dr. Marshall is a specialist member of the American Association of Endodontists and has been consistently selected by his peers as one of the top endodontists in New Hampshire.  In fact, he has been bestowed this honor again this year (see the Bulletin Board posting below).  His mission is to provide unsurpassed quality in an environment of professionalism, caring and clinical excellence.  Please enjoy our website to learn more about endodontics and see how we can help you.  Please click on this:  “Testimonials”,  and also visit our Google page (where there are dozens of reviews), to see what our patients have to say about their experience with us.  




Again selected as one of the top endodontists in the state!

We are pleased to announce that Dr. Marshall’s peers once again selected him as one of the top endodontists, in the entire state, for 2023.  He is especially proud to have been selected as the very top vote getter twice, in recent years.  As explained by “New Hampshire Magazine” (in the August issue), because this honor “is based on an exhaustive peer-review survey in which dentists and specialists throughout New Hampshire cast votes on the ability of other dentists and specialists, inclusion in ‘topDentists’ is considered a singular honor”.  




CBCT technology is certainly the most important technological advance in endodontics since the surgical microscope.  It allows for three-dimensional viewing of a tooth and the surrounding hard tissue structures.  Having this technology available, in order to provide state-of- the-art endodontic care for patients, requires an exceptional commitment on the part of the endodontist.  First, the cost of the equipment and installation is substantial.  Second, because the volume of information is so large and different in appearance, compared with conventional radiography, many, many hours of continuing education and practice are required for the doctor to become proficient in reading three-dimensional scans.  Third, it usually takes one to two hours to read a scan, and then process and convey the information.  However, the information which can be attained is unbelievable and often proves to be essential in the proper handling of a case.  I incorporated CBCT technology into my patient care, more than four years ago, and am continually amazed and astounded with the unexpected information I receive from a 3-D scan.  Without doubt, it is amazing and now an essential innovation, in the world of endodontics, and is destined to be considered the standard of care, at some point in the future.  Follow this link to learn more specifically how 3D technology helps in the care of my patients.   



Our office has CBCT technology!  The benefits of three-dimensional imagery in endodontics are tremendous, since it allows for more accurate diagnosis and an understanding of what might be the best treatment (without having to actually enter the tooth).  In addition, it increases the chances of providing successful endodontics, when complexities are present, so they can be observed and understood, before the treatment is even started.  It is just another way of providing patients with the best care possible.  Please open this link to learn more about this exciting technology and supportive research:  3D images with our CBCT
