When To Get a Root Canal Howell, MI

The Endodontist, the General Dentist and Root Canals

All dental school graduates have basic education and training in the diagnosis and treatment of diseases of the tooth pulp and are licensed to perform a routine root canal procedure.

What Is an Endodontist?

An endodontist is a dentist who has completed an additional two to three-year course of study in an accredited endodontics postdoctoral residency program. In addition to performing routine root canal treatment and tooth pulp treatments, the endodontist has extensive training and experience in the diagnosis and treatment of a wide variety of conditions, such as:

• The differential diagnosis of painful oral and facial conditions in which the origin of the pain is uncertain. In these cases, the root canal dentist is part of a team, which may include other specialists in dentistry as well as medical colleagues, when appropriate.
• Endodontics treatment of teeth involved in cases of oral-facial trauma.
• Endodontic treatment for patients who are medically compromised.
• Endodontics treatment of complex root canal cases, such as teeth that exhibit calcified canals, curved canals, or very long roots.
• Non-surgical re-treatment of teeth that have had previous root canals.
• Surgical treatment of endodontic disease that can be treated in no other way.

There are ethical guidelines that determine what an endodontist can and cannot do. As an example, an endodontics specialist would not place crowns, dentures, or perform orthodontic procedures.

Following the completion of a root canal procedure, a patient is usually referred back to the general dentist. At times, however, in a complex situation it may be necessary for the endodontist to refer a patient to another specialist before the patient returns to their general dentist.

Why Are Patients Referred From a General Dentist to an Endodontist?

Patients are referred from a general dentist to specialist because a dental problem may be so complex that its successful diagnosis and treatment require considering a multitude of complex factors.

A "multidisciplinary" approach allows the patient to have expert opinions from different generalists and specialists so that the best of science, art, and technology can be utilized in a particular set of circumstances.

Oftentimes, an individual dentist is more interested and experienced in some areas of dentistry than in others. A general dentist may choose not to do certain procedures because:

• They do not have the equipment, instruments, or training necessary to do the procedures.
• The time involved to do the procedure well is more than they wish to spend.
• Particular teeth may exhibit complex treatment challenges.
• The patient may have medical or other complicating factors.

In short, the primary consideration for referral is that the patient has the opportunity to have the best diagnosis and the best care available. A patient may be referred from a general dentist to specialist to make certain that this goal is attained.

Endodontics: What Happens at a Root Canal Appointment?

At the root canal treatment appointment, whether it is an emergency visit or a regularly scheduled visit, the patient will be cared for by various members of a trained and professional team. A primary goal of the dental team is to make certain that the patient is comfortable physically and emotionally during every stage of treatment. In addition to relieving tooth pain, if present, the goals of endodontic treatment are to eliminate endodontic disease and move the patient towards a state of health. With modern endodontic techniques, these goals can generally be achieved. Root canal treatment may take one or more visits to complete and usually progresses through the following stages:

1. The dentist reviews the findings and recommendations from the examination and consultation visit. If any additional radiographs are needed before starting treatment, they may be taken at this time.
2. The patient is typically given a local anesthetic. With newer techniques and devices, these anesthetics can usually be administered painlessly. The tooth can be made "profoundly" numb so that the patient is completely comfortable during treatment.
3. After achieving the required level of anesthesia, the dentist "isolates" the tooth using a "dental dam." This is a sheet of rubber material that fits over the tooth to be treated and forms a tight seal around it. The rubber dam serves to keep the saliva away from the area being treated and it also prevents the various disinfecting and cleaning solutions used during the procedure within the tooth from entering the mouth.
4. After the tooth has been isolated, the dentist prepares a window (an "access" opening) through the biting surface of the tooth in order to gain access into the diseased root canal space.
5. Once the access preparation is complete, the dentist begins to "clean" the root canal space by removing the diseased pulp tissue, bacteria, and related irritants. This is done using special solutions and small flexible instruments, called "files." The solutions penetrate and clean areas of the canal where the instruments cannot physically reach.
6. As the root canal system is being cleaned, it is also being "shaped." Shaping is the process of enlarging the root canal space in such a way that it can be thoroughly cleaned and subsequently filled and sealed. A root canal space that is not properly shaped may still harbor bacteria.
7. Following cleaning and shaping procedures, the root canal space is ideally filled and sealed in all its dimensions by a dentist. This is most commonly accomplished using a sealing cement in combination with a unique material called "gutta percha." Gutta percha is a special material that can be softened with heat and then pressure molded to precisely fill the root canal space.
8. Once the tooth is three-dimensionally sealed, it is generally "provisionalized" (temporarily restored) until a more long-lasting protective restoration can be placed. A protective restoration helps minimize the chances of future tooth fracture.
