Peculiarities of Nerve Removal in Tooth


If the injury or illness caused the lesion of nerve of the tooth, then in the vast majority of cases there will be the necessity of depulpation. This procedure actually “kills” a tooth, but retains its functionality.

What Is Depulpation?

Depulpation is the extraction of the pulp (it is sometimes referred to as the tooth nerve) – connective tissue, consisting of vessels and nerve endings. A nerve removal in tooth is meant to relieve the patient from pain, inflammation and further complications. However, a tooth deprived of blood supply becomes dead and therefore more fragile. Dental treatment is sometimes accompanied by removing the nerve in tooth – it is one of the most common dental procedures. Partly, this occurs because patients resort to the dentist only when a tooth causes a great deal of pain – when it is impossible to do without depulpation. Removal of the nerve of the tooth and filling of the canals allows of preserving a natural tooth, which is a priority for endodontic treatment. Indications for the nerve removal:

  • nerve removal in teethCervical caries;
  • classic and infectious pulpitis (bacteria penetrate through the root tip);
  • injuries of a tooth, affecting the pulp;
  • necessity of installing crowns or bridges.

Many patients coming to the dentist office with a toothache are concerned about whether it is possible to preserve the nerve. Today there are methods of biological treatment and vital amputation, but for such methods there must be a lot of favorable factors. For example, biological treatment is not carried out after 25 years.

Removal of the Nerve of a Tooth with Arsenic

The removal of the pulp with arsenic is considered a quite old-fashioned method, which today is almost not applied. The negative side of this treatment is that arsenic is strong poison, which adversely affects both a tooth and its surrounding tissue. Since there appeared many more effective methods, there is no need in application of arsenic any more.

Modern Method to Take Out Tooth Nerve

Today for removing a tooth nerve dentists use a pulp extractor – a very thin metal rod that can penetrate even in the remote areas of the root canal. The device called an electronic apex locator helps to determine the depth of the channel to reduce the risk of injury. Usually after the procedure a temporary filling is set, but it may also be a constant one, if the doctor doesn’t see the risk of some complications and has high-precision instruments such as dental microscope.

Possible complications after removal

A Fragment of Tool Left in the Tooth Channel

It is a common complication concerned with the negligence or inexperience of a doctor. Re-treatment involves the removal of fragments of the tool and re-filling of channels. Due to a number of factors, the removal of an exterior body may be very complicated. Pain after removing the tooth nerve occurs not vary often, so in some cases a doctor recommends leaving it as it is, if the complication does not manifest itself.

Not Fully Removed Nerve or Poor Filling of Root Canal

This is the most common reason due to which you experience pain after depulpation. In this situation, an inflammation occurs, which extends to the root tip, causing the formation of periodontal cysts and flux. If your tooth aches after the nerve extraction for several days or more, you should consult a doctor who will be able to examine the filling.

Re-filling and Perforation of the Wall or Root

nerve removalIt appears when the filling material goes beyond the apex. In not serious cases, for some time after extraction of the nerve, the tooth aches when pressure is applied, and then the pain passes away. If the surplus of material is large, in order to avoid complications, operational intervention is necessary.

It concerns mechanical damage, which results in the hole in the wall, the bottom of the dental cavity or root. After the nerve extraction, the tooth continues to ache. The pain is usually paroxysmal.

Tooth Darkening after the Nerve Extraction

If there occurs tooth darkening after the nerve extraction, this can be caused by poor filling material of bad quality of depulpation carried out. Also, over time a dead tooth can be covered with cracks and become more vulnerable to dyes. This partly explains why the front tooth after removal of the nerve is subsequently closed by a crown or veneer.

What if after Depulpation a Tooth Aches?

You must consult your doctor if after the removal the tooth aches a week or even longer, and the following symptoms persist for a long time:

  1. The tooth aches when pressed.
  2. The tooth aches when tapped.
  3. The tooth too much responds to hot and cold.
