What Is The Difference Between a Root Canal Specialist and a General Dentist?

A Root Canal Specialist (Endodontist)

A root canal specialist, also known as an Endodontist, must undergo a minimum of 2 additional years of postgraduate training before being qualified to apply for licensure by his/her respective State Dental Board as a specialist.

Root Canal Specialists have a wide-range of equipment used primarily to do root canal treatment. Endodontists use microscopes during treatment to better treat the small internal anatomy of teeth to assist in removal of minimum tooth structure. Very few general dentists have dental microscopes in their offices. Most Endodontists use digital radiographs which enable processing in seconds and reduces the amount of x-ray exposure by 90%. CBCT (3D Cone Beam imaging) is mostly for placement of dental implants, but CBCT has been shown in a rare few cases to help diagnose chronic pain, complicated surgery, and accidents. The drawback on CBCT is the cost ranges from $250 to $300 and dental insurance does not pay for these type of radiographs. If CBCT is necessary for your diagnosis, our office can arrange discounts to patients who require CBCT for any reason. Dr. May does not have a CBCT in his office to keep down costs of treatments as such a machine costs around $150,000. If an office has CBCT/ 3D imaging, then more patients will be asked to use this device for diagnosis.

Most root canal specialists (Endodontists) have a national 95% success rate if there has been no prior RCT. General dentists have a national success rate of 80%: These statistics have been quoted in Dental text books for over 30 years. However, their fees can be lower or higher than a root canal specialist. There are no regulations on fees for service in dentistry. It is wiser to have a Specialist in Root Canals perform root canal treatment due to his equipment, education, and training as a Specialist verses a couple of courses dental school. 
Removal of majority of bacteria in canals

For many years, technology prevented the removal of all the bacteria from the root canal space.   This led to the principle of entombing bacteria in the root canal space. Recent research revealed that 30% of the original walls of the root canal are never touched and 10% of the original bacteria remains in the finished root canal.  Dr. May has used LASER ENHANCED Root Canal treatment  to remove  99% of the bacteria when he preforms root canal therapy.   Dr. May is the only dentist who uses Laser and sonics to remove bacteria in root canals.

A General Dentist

A general dentist is the first and key member of the dental team to good dental health. Without your general dentists, most patients would not have a clue whether or not they have an abscessed tooth. Most dentists are experts on diagnosis and treatment plans for their patients' dental health. Most dentists cannot be a master of every aspect of dentistry. Your dentist relies on the training and education of dental specialists like Endodontists, Oral Surgeons, Orthodontists, and Periodontists as team members to assist the general dentist.

Although general dentists can perform endodontic treatment, several things set a general dentist and a root canal specialist apart. Dental students at the University of Missouri-Dental School have the limited training of one hour per week for two semesters of class room education on root canal treatment while these students have a student work load of approximately 25 hours/ semester. The average college student work load is about 15 to 16 hours. With a 25-hour load/ semester with over ten subjects, a most dental student does not have the time to devote to advanced training in root canals/ endodontic or any other specialty.

One really cannot compare root canal treatment by a root canal specialist and a general dentist. Root canal specialists perform root canal treatment on most of their patients where General dentists perform root canal treatment 2 to 3 time per months. Plus, root canal specialists have far more sophisticated equipment suited to assist the Endodontist in the simple to complicated treatment where general dentists cannot afford these types of equipment. Such equipment has a limited use of performing root canal treatment.
