Welcome to Southern New Hampshire Endodontics

Thank you for your interest in Southern New Hampshire Endodontics. By referring you to our office, your dentist has shown confidence you will receive the finest endodontic care possible.  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 and learn more about endodontics and how we can help you.  Please click on this:  “Testimonials” to see what other patients have to say about their experience with us.


Dr. Marshall has added 3-D technology to his practice.  Conventional digital images can only be viewed in two dimensions, so although much information can be attained from them, there are obvious limitations.  With three dimensional images the tooth can be examined from every angle imaginable, plus a multitude of viewing slices can be taken of a tooth.  The benefits are tremendous since this allows for more accurate diagnosis, an understanding of what is the best treatment without having to actually enter the tooth and increases the chances of providing successful endodontics when complexities are present.  Carestream is the largest provider of this technology in the world and the CS 8100 3D is their latest model.  At the recent American Association of Endodontists meeting a lecturer reported only 23% of the endodontists in the country have a cone beam machine.  It is just another way of providing patients with the best care possible.  Please open this link to learn more and explanation of cost:  3D images with our CBCT

Dr. Marshall and his daughter, Bailey (who just completed her junior year at UNH and fills in at the office occasionally) ran in The Run to Remember half marathon over the Memorial Day weekend.  The 13.1 miler is through the heart of Boston and along the Charles River and benefits the children of fallen police officers, fire fighters and rescue personnel.  It was a great day for the event, nice and sunny and a perfect temperature — it was a fantastic morning! 

USA Top Dentists surveyed the area dentists and asked, “If you had a patient in need of a dentist, which dentist would you refer them to?” and Dr. Marshall  was again selected by his peers as one of the top Endodontists in the state of New Hampshire, as reported in New Hampshire Magazine.  He is honored to again receive this distinction.  In 2016 he was the top vote getter in the endodontist category.    

Dr. Marshall recently attended the annual American Association of Endodontists meeting.  There were literally hundreds of lectures, demonstrations and presentations by some of the worlds most renowned educators and research scientists on many topics, as well as displays of the most recent equipment and innovations.  Whereas the local educational forums are typically  designed for general dentists, this event is specific for the specialty of endodontics and specialists from all over the world usually attend.  This forum allows endodontists the opportunity to stay on the cutting edge of new information in order to better care for you.

What is a root canal?

Endodontics, commonly known as root canal therapy, is specialty area of dentistry which deals with saving teeth that might otherwise require extraction.  It is also one of the most common dental procedures and when provided in a careful and compassionate manner, can be one of the easiest to receive.  With well over 14 million performed every year, this simple treatment can save your natural teeth and prevent the need for dental implants or bridges. Losing any tooth, front or back, will have consequences for your appearance, chewing ability and overall health.  A missing front tooth can cause embarrassment.  The loss of a back tooth can seriously affect your ability to chew food properly and cause teeth to shift, which could have other long-term consequences.  Endodontics involves carefully cleaning and shaping the inside of a tooth, then filling and sealing the canal space with a special root filling material.  Depending on the condition of your tooth and your personal circumstances, modern root canal treatment is very similar to having a routine filling and usually can be completed in one or two appointments.  Afterward, you return to your dentist, who will place a crown or other restoration on the tooth to protect it and restore it to full function.  Remember:  nothing looks, feels or functions like your natural tooth!  For more information regarding endodontics and how we might be able to help you, please visit our Root Canal Therapy page under our “Procedures” tab.

Are there specialists who only do root canals?

Endodontists are specialists in root canal therapy.  They have completed four years of dental school and then received at least two years of additional, post-graduate training in endodontics.  By limiting their practice to only endodontics, they are known as experts in this field of dentistry and perform routine as well as difficult and very complex endodontic procedures.  As a result of their specialty training and years of experience, endodontists are skilled in finding causes of oral and facial pain, managing and relieving tooth pain, treating traumatic injuries to teeth, as well as dealing with calcified, tortuous and intricate canal systems.  Dr. Marshall has more than 20 years of experience as an Endodontist and has achieved a reputation for providing excellent care in an extraordinary manner.  He utilizes state-of-the-art technology, including digital imaging, operating microscopes, ultrasonic instrumentation and fiber optics while performing root canal treatment.  Advanced technologies, together with specialized techniques allow for very accurate and comfortable treatment.
