One of the most unpleasant types of pain is dental pain . It may not be intense and unbearable, but it brings considerable discomfort to a person. The tooth can get sick both before the treatment and after. Frequent complaints of patients that the tooth whines after removal of the nerve. Such pain can appear for various reasons.
What happens to the tooth after removal of the nerve?
The nerve, as its patients or pulp, as its dentists call it, is a small but really important organ of the dentoalveolar system of man. It consists not only of nerve endings. The basis of it is a connective tissue, densely permeated with blood vessels (blood and lymphatic), as well as nerves proper. It fills the entire cavity of the tooth from the crown to the root. The functions of the pulp include:
- innervation;
- blood supply;
- stimulation of regenerative processes in the tissues of the tooth with carious lesions;
- a biological barrier (it is the pulp that protects the periodontal tissue from penetration of bacteria through the root canal).
When the carious process still affects the pulpous tissues, pulpitis begins - inflammation of the pulp. This diagnosis requires immediate treatment, which often leads to the fact that the tooth hurts after the removal of the nerve and is in the following stages:
- Disc opening of the tooth cavity, preparation of carious tissues.
- Removal of pulp (partial - amputation or complete - extirpation).
- Drug and instrumental treatment of the root canals (can be carried out in several stages, with a temporary dressing between them depending on the shape of the pulpitis).
- Imposition of permanent filling or aesthetic restoration of the tooth.
Often the tooth pulsates and hurts after the stage of nerve removal. This phenomenon can be compared with a fresh wound, because the dentist interfered with the structure of the tooth and removed with the help of tissue tools of the body. A small part of the nerve fiber comes off, the same happens with the blood vessel. If such painful feelings do not last long, for several days, then it is not necessary to sound the alarm. It is enough to take an anesthetic to muffle the pain and in a few days they will pass by themselves. If, after 4-5 days, the pain continues or worsens, it is necessary to consult a doctor, as it may indicate poor treatment of the root canals or an allergic reaction to the filling materials.
Why does the tooth darken after removal of the nerve?
Darkening of the tooth after removal of the nerve is most often due to the fact that the tooth is no longer blood flowing and not innervated properly. Of course, a certain amount of useful nutrients and minerals still gets into the tooth tissues from the periodontal tissues. This is enough to keep the tooth still for many years, but it is not enough for its whiteness.
Another reason for the fact that after the removal of the nerve of the tooth has darkened, there may be poor quality instrumental and medicamentous treatment of the root canals, as a result of which necrotic remains of the pulp remain, as well as bacteria that affect the color change of the crown.
And the last reason, leading to a discoloration of the tooth after treatment, is the use of some filling materials. These include filling materials containing silver or resorcinol-formalin-based materials. The latter can lead not just to a darkening of the tooth, but to the appearance of a pink shade of the crown. Fortunately, in modern dentistry such materials are used very rarely, and modern materials do not lead to problems.
