Nerve removal

In order to decide on the removal of the pulp( nerve), the specialist should have a basis. Treatment of canals is a forced measure. In addition, depulpation is a complex process. The patients are accustomed to call the pulp system a nerve. Its appendages are very thin. And the channels that fill the pulp are often meandering. This makes access difficult for the specialist.

In addition, the procedure performed by a doctor is almost blind. It is not possible to monitor the process visually by a specialist. Sometimes, even with the help of an X-ray, it is not possible to examine in detail the entire "labyrinth" of the canal channels. The snapshot is not able to display the nest processes hiding behind each other. There are also too narrow channels with atypical entrances. It is not easy to extract pulp with all its branches. After all, if you leave at least one "tail", problems will begin. The patient will face the fact that his tooth hurts again. Without a nerve and with sealed canals, it would seem, he should not bother. Now we have to understand the reasons for the pain.

Can a toothache without a nerve?

Why does the tooth without a nerve have a sealed tooth?

In part, we answered this question when we considered the depulpation process. Since it is carried out almost blindly, mistakes in dental practice are very common.

There are several other reasons why the tooth without a nerve hurts:

  • It was not possible to clean the channels to the very end. Repeated treatment of the tooth, in which the channels were already filled with paste, sometimes leads to the situation in question.
  • Introduction of material beyond the tip. There may be a complication in the form of inflammation of the jaw nerve.
  • Insufficient washing with antiseptic canals. Microorganisms do not have time to die. As a consequence, the inflammatory process develops.
  • Failed to completely fill the tooth canals. In the formed voids, pathogenic bacteria are almost always found. And this error of the doctor leads to that the tooth without a nerve at nibbling hurts.
  • Part of the toolkit can break and stay in the channel. Accordingly, the foreign body will not allow for qualitative treatment.
  • Inaccuracy of the doctor sometimes leads to perforation of the walls or apex of the root. All this will certainly lead to complications in the form of an inflammatory process.

What causes errors?

As we have already understood, the unprofessional actions of the dentist very often lead to the fact that the sealed tooth hurts. Without a nerve or even with the smallest of its remnants, it will greatly disturb the person. If mistakes were made during endodontic treatment, a cyst or granuloma may develop. Often the inflammatory process inside leads to swelling of the gums. After a while, a purulent abscess appears in the area of ​​the aching tooth, which is called a flux. In this situation, a person should immediately seek help from a specialist. The tooth itself begins to ache when pressing on it.

The nature of the pain can vary in intensity. A person experiences discomfort during the temperature difference( hot and cold food intake), with weather change.

Also the untreated tooth differs and externally from the remaining units. Over time, the enamel darkens. To all the rest is added an unpleasant smell from the mouth.

Statistics show that removal of the nerve passes without errors only in half the cases. That's why almost every patient can be familiar with the situation when the tooth without a nerve hurts.

Separately, let's talk about such an unpleasant phenomenon as a cyst. In order for the neoplasm to express itself pain, it may take a long time. Therefore, the tooth, whose channels are not filled to the end, first does not bother the patient. And only when the cyst reaches a large size( about 20 mm), a person feels pain. The moment of its development passes asymptomatically. But the reason for its formation is still an infection that has gone beyond the root of the tooth. Statistics show that in 70% of cases, education develops due to the fact that the channels are not completely filled with the material for sealing. To testify for the presence of a cyst, the following symptoms may occur:

  • swells around the gum;
  • pain during chewing food;
  • increases the size of submandibular lymph nodes;
  • change in enamel color or even unit mobility;
  • may cause fever.

But even in cases where the cyst does not cause the patient discomfort, it is still dangerous. It's a capsule filled with pus. The infection can spread to healthy tissues, causing complications in the form of periodontitis, periostitis, osteomyelitis and even sepsis.
