How is a root canal treatment done? When is it necessary?
3D video of Clínica Médico Dental Pardiñas ([ Ссылка ]) about endodontics, a dental treatment for deep cavities and/or dental destruction.
This treatment is necessary when the nerve of the tooth is irreversibly affected by caries, trauma, or wear, etc. As the caries progresses, the damage caused to the tooth may be more or less superficial, meaning it may only affect the external layer of the tooth (the enamel), but may continue until it reaches the internal tissues such as the dentine and finally the dental pulp (the nerve of the tooth). Depending on the advance of the disease (its size and depth), symptoms may appear ranging from slight pain or discomfort, through to severe, incapacitating pain accompanied by abscesses and even fever. Generally, the closer the caries is to the dental pulp (the nerve), the more painful and damaging it is.

There are other causes that may affect the nerve of the tooth, such as traumas (impacts caused by sporting and traffic accidents, children's accidents, etc) which also cause pain and require immediate treatment.
Finally, and no less important, are destructive non-bacterial processes (wearing of the teeth). These may be physiological (due to the patient’s age) or pathological, caused by bad habits such as overly aggressive brushing, using highly erosive toothpaste, onychophagy (biting your nails), or bruxism (grinding and clenching your teeth). In many cases, the loss of tooth tissue is so severe that it may affect the nerve, causing different clinical symptoms such as sensitivity (felt when eating or drinking cold things, sugary foods, acidic foods, etc.), pain and abscesses.
First all infected material is removed from the tooth. After that, a series of files of different lengths and widths are used to remove all the infected material from the roots.
The area is irrigated with disinfectant liquid and dried. At last, the roots and the inside of the tooth are sealed with different materials.
Once finished, the infection will be slowly reabsorbed until it disappears.
There are cases where the destruction of the tooth is so big that once the root canal treatment is done, the tooth gets very weak, so it is necessary to make a crown. For doing so, the tooth is prepared, and some molds are taken to manufacture the crown that will be cemented to the tooth.
In other cases, the destruction of the tooth is bigger, so it is necessary to place pins inside the tooth to give the crown more support and stability.
