Fundamentals For A Root Canal Therapy
RCT is one name that gives many patients shivers when told about it. However, in reality, it is not that scary. In fact, it is an instant pain reliever and the best treatment to retain your original teeth. Fundamentally, it is one of the most common dental procedures, also known as endodontic treatment.
A root canal is the space within the root of a tooth. It is part of a naturally occurring space within a tooth that consists of the pulp chamber (within the coronal part of the tooth), the main canal(s), and more intricate anatomical branches that may connect the root canals to each other or to the surface of the root. The smaller branches are most frequently found near the root end (apex) but may be encountered anywhere along the root length. There may be one or two main canals within each root. Some teeth have more variable internal anatomy than others.
This space is filled with a highly vascularized, loose connective tissue — the dental pulp. The dental pulp is the tissue which forms the dentin portion of the tooth. Once the tooth has reached its final size and shape, the dental pulp’s original function ceases for all practical purposes, taking on a secondary role as a sensory organ.
Why May Endodontic Disease Cause Swelling?
When the pulp tissue becomes severely diseased and necrotic, the resultant infection can spread from inside the tooth into the adjacent bone and soft tissues. As a result, swelling can occur in different parts of the face and the infection can cause extreme pain.
In most cases, the infection can be brought under control by the body’s defenses. However, the infection can begin to spread into other tissue spaces, and what began as an acute situation can become a serious medical emergency. Natural teeth are the ones best suited for the mouth — preserving them is always the priority.
Everything You Need to Know
Answers to the most common questions about root canal treatment.
If you have any of the below-stated symptoms, it would be advisable to visit your dentist, since they are best placed to judge whether you have a root canal disease or not, as some of these symptoms may be due to other problems as well.
- Severe tooth pain, typically relieved by cold water and increases with the intake of hot liquids.
- Pain worsens when you lie down and reduces when you sit up.
- The pain stays for a long time after consuming cold things.
- Swelling around the tooth.
- Constant tooth pain.
- Pain when chewing.
- Tooth pain referred to head and ears as well.
- Tooth sensitivity on consuming sweets.
Despite providing excellent success in preserving oral health, some treatments fail. The significant technological breakthroughs that benefit both dentists and patients in endodontic retreatment include:
- Magnification glasses, fibre optic lighting sources, and headlamps have significantly improved vision and access.
- Ultrasonic devices allow doctors to more efficiently and completely remove old root canal filling materials.
- 3D cone-beam CT scans allow the doctor to better diagnose, visualize, and treat root canal disease, while significantly reducing radiation exposure.
- Improved instruments, better materials for filling and repairing canals, and innovative new technologies have significantly improved patient care.
Non-surgical root canal treatment is a procedure directed towards saving an endodontically failing tooth. An access opening is created through the biting surface of the tooth to give the dentist access into the root canal space. Once accomplished, the following is performed:
- Locating and treating previously missed canals.
- Removing all filling materials from the root canal space.
- Removing posts and broken instruments.
- Enlarging existing root canal treatment.
- Repairing mechanical and pathological perforations in the root.
Once these objectives have been accomplished, the root canal system is re-cleaned, re-shaped, re-disinfected, and bio-mechanically sealed.
Surgical root canal treatment involves devoting a small flap of gingival tissue to evaluate the point of periapical pathology. Also known as an apicoectomy, it involves the removal of the root tip and surrounding tissue. When the periapical tissue is exposed, the doctor performs a curettage to remove the diseased tissue, then a root-end filling is placed so that the remaining root canal space can be effectively eliminated.
Today, well-trained general dentists and specialists can often perform non-surgical endodontic procedures. However, re-treatment cannot always be managed non-surgically. In these situations, and as an alternative to extraction, a surgical approach may be necessary.
