A toothache is considered the most powerful and unbearable. The pulp consists of nerve endings, blood vessels and connective tissue. But the common people simply called tooth nerve. It is removed when it becomes inflamed or have broken down due to the presence of bacterial microflora. When the nerve is still alive and he inflamed the disease is called pulpitis. But if he’s dead and the inflammatory process has gone beyond the apical hole, it is periodontitis.

There are times when, and in periodontitis the pulp maintains its vitality. In any case, it must be removed. Otherwise the process will not stop in the periapical space, and go down to the bone and even to soft tissue. To avoid such complications, as periostitis, osteomyelitis, abscess, phlegmon better with the appearance of pain symptoms to seek help from a dentist.

How is deponirovanie tooth on

Pulp removal can be carried out devital or vital way. These two option is possible in the pulpit. Using the first method, at first sacrificed the neurovascular bundle using overlay at autopsy pulp horn ARSENICAL paste. The second method to be performed in one visit under local anesthesia. In periodontitis, the nerve is already dead in most cases. If the sensitivity of the saved, then again, numb. For a start, treat a cavity, then reveal the chamber where the pulp is. Then open it and remove the crown part. It is necessary that the wall was smooth, no ledges. So access to the channels will be better.

Then find the mouth of the channel and expand them. From that moment begins the most difficult. You need to fully remove the nerve from the canals. This is done with a special tool — pulpectomies. Unfortunately, sometimes it happens that the channel is too narrow and pulpectomies does not fit in it. He should be able to cling to the wall, get stuck and break. Therefore, if there is a concern that the nerve bundle should be removed by other tools. After this step, measure the length of the channel, expanding its walls and level them.

Possible causes of pain after removal of tooth pulp

Why toothache after removal of the nerve? If it’s not postproduzione sensations, the next common cause is the withdrawal of the filling material beyond the root canal. Toothache occurs immediately that day. How long it will take and how much depends on many factors:

  • The number of the extracted material;
  • Composition;
  • How the human body perceives a foreign substance;
  • The presence of any allergic reactions to components of the material.

This error occurs due to incorrect measuring the length of the root canal. As a consequence, take a pin and place it in a channel does not fit and he, along with filling beyond the apical hole, irritating the tissues of the periodontium. This cause of pain after removal of nerves can be identified on sighting the radiograph. Competent doctor will be able to eliminate this cause. If the patient is not immediately treated, it can hurt a tooth after removal of the nerve for up to six months.

Failure of endodontic instrument in the canal

This is one of gross and harmful errors of the dentist. Because it can lead to tooth loss because of the doctor. When the mold tool and the doctor sealed the tooth, not picking a broken piece, there is a risk of infection. Because of this piece of channel is impossible to fill to the end completely. Some time later tooth aches. Take a picture and there’s visible to the rest of the piece. The more time passes, the harder it is to get. Therefore, if the dentist found a problem he will do everything to rectify the situation.

The most common causes of these errors:

  • Work in the dry channel that is not used with a special gel for the chemical expansion of the walls of the channels;
  • Excessive application of effort during instrumental treatment;
  • Using old, blunt tools;
  • Violation of proper technique of endodontic treatment.

A broken tool can be get by using ultrasonic vibrations or expansion of the channel in this area. If you cannot remove, resect on the testimony or the tooth is removed.

Low-quality filling of root canals

Many doctors who are confident in themselves do not conduct x-ray control after endodontic treatment. Which is too bad, because it can be so that the channel walls do not end up obturatoare. In other words, there was a space filled with a filling material. If not done good sealing in these areas breed bacteria, causing inflammation. This tooth pain does not occur immediately. After some time there is pain in the tooth, sore gums in this area. And the patient the question arises why a sore tooth with no nerve? The inflammatory process may go to the tissues of the periodontium, where innervation is preserved. Hence the pain in the tooth after removal of the nerve. In this case, all the work on the canal treatment is necessary to pass again completely and more carefully.

Perforation of the root walls or the bottom cavity of the tooth

This problem occurs when the doctor is not competent or the sides and bottom too softened. Perforation in dentistry is the creation of holes in the wrong place. In the treatment of pulpitis and periodontitis, first open the cavity, then looking for the mouth of the channels. If you do not know their approximate location, i.e. the probability to drill the bottom. A doctor may not immediately identify and accept for what found channel. But a qualified specialist will understand immediately that it is not to be in the channel. The patient in spite of the anesthesia, the pain appears. It draws blood. Unfortunately, the exact location of the mouths, no one knows, because every tooth has an individual structure of each person. But still some points worth knowing.

Perforation of the root wall occurs when instrumental treatment when the channel is too curved or narrow and impassable. Trying to expand it and go to physiological tops, the dentist can pierce through the wall. The signs are the same as in perforation of the bottom. In both cases, the importance of detection time. Assuming this error, the tooth could get sick immediately. You need to put anti-microbial and anti-inflammatory medication for a while. If you do not help and the pain does not pass, the tooth must be extracted.

An allergic reaction

This reason is not as common. But still there are cases when any component is not suitable for that person. Based on this, may be ill treated tooth. Gums after removal of the nerve can react on the material. It may cause itching, redness and rashes. The faster the doctor will determine the presence of Allergy, the better. In such situations, it is necessary to completely remove filling material and re-sealed Hypo-allergenic.
