Functional need for pulp
The dental nerve is the bottom part of the tooth. It consists of two parts - internal, hidden in the tissues and external, entering the tooth and hidden under the enamel. In order to better understand what a nerve is, you need to know the structure of the tooth:
- top layer - enamel;
- dentin;
- in the center is a pulp, blood vessels and nerve endings.
The nerve leaves in soft tissues. There are large and small nerve endings, while in the single-root tooth there is 1 root, and in the tricorn, respectively, three.
Small endings are woven into a single network. Painful sensations come at a time when tooth decay reaches the middle - the pulp.
The main function of the dental nerves is to ensure the intake of nutrients necessary for normal development and growth of the teeth. In addition, they perform a sensory function, which allows you to learn that the tooth and tissues are beginning to deteriorate.
Inflammation of the pulp - and it hurts, itches and looks for
Inflammation of the dental nerve, in addition to getting into the teeth of bacteria, can result from injury to the crown or fracture of the tooth.
In this case, access to the pulp is available. It is important to understand that the infection will quickly penetrate into the cavity. If nothing is done, the first signs of the inflammatory process will be visible after a couple of hours.
Another reason for the inflammation of the dental nerve is the rough treatment of the root canals. Also, the toxic effect of the material used to make the seals may have a negative effect on the health of the nerve.
In addition, overheating of the tooth can lead to the onset of the inflammatory process. Surgical interventions are also one of the reasons for this unpleasant situation.
Symptoms of the inflammatory process are familiar to everyone: 
- twitching;
- itching in the gum area;
- incessant drawing pain, increasing with each hour.
Drugs with time cease to help, so going to the dentist is inevitable. Externally, the inflammation can manifest itself in the swelling of the cheek from the patient's tooth-flux. Then we can say that there is pus there.
Causes of Pain Syndrome
Inflammatory processes begin not just because there is a need for this. Diseases of gums and tissues can become major if the tooth looks healthy or tooth decay is present in the initial form.
Also, inflammation can be a consequence of pathological processes occurring in the neuromuscular bundle. Also, the causes of problems with the root of the tooth can be:
- deep tooth decay - caries;
- various diseases of gums;
- trauma of a mechanical nature;
- chronic diseases;
- errors in the treatment of teeth.
Inflammation of the nerve in the tooth always, regardless of the cause of its occurrence, is accompanied by similar symptoms:
- acute or throbbing pain;
- increased susceptibility of the tooth to hot, sour, cold or salty;
- by the appearance of an unpleasant odor.
In most cases it is possible to save the tooth by putting a seal, in the early stages of the disease it is possible to save the nerve, but if the inflammation process is started, a flux will appear, therefore, suppuration will occur, which can lead to a risk of blood infection.
Other factors that cause nerve disease include poor oral hygiene, a rare visit to the dentist, a lack of vitamins or an overabundance in the body.
Caries provokes pain and discomfort
A person often faces such an unpleasant situation as a sudden pain in the area of the dental nerve. There are many reasons for this:
- dental diseases;
- inadequate oral hygiene;
- error of doctors during dental procedures.
The most common pulpitis occurs when a person is inattentive to the health of the mouth, because the nerve can get sick in case of caries.
After the integrity of the tooth crown is broken, a cavity is formed in it, gradually increasing in size. It penetrates harmful microorganisms and, reaching the pulp, hit it.
Open nerve - which can be worse
Bared nerve of the tooth is formed for two reasons:
- dentist error;
- started caries.
Symptoms of the problem: acute pain, which manifests itself not only when pressing on the tooth, but also in the usual situation.
In some cases, there may be an increase in body temperature, as the body's response to the effects of bacteria.
