It is very common to feel tooth pain after nerve removal. Many patients suffer from this pathology. They can go away on their own within 7 days but if this is not happening, it means there is something wrong. It is possible to tell about several the most widespread reasons of this issue:
- The out put of the filling paste over the apex of the root. One of the most common mistakes is the penetration of the filling paste outside the root, that is, into the tissue of the jaw bone. Since the paste is a side body, an inflammation develops around the treated tooth, which causes unpleasant sensations and tooth pain after nerve removal. To avoid such an error, the dentist should conduct a thorough preparation for the procedure, and then make an x-ray to control the quality of the manipulations. Preparation is needed to measure the length of the channels with the help of special tools. So-called K-files that are connected to the apexlocator are entered into the channel. On the screen of the last doctor will see when the tool reach the top of the root, and will be able to determine its length. Then the doctor needs to measure the length of each channel. Upon completion of the measurements, the K-files are entered simultaneously into all channels for their entire length, after which a control x-ray is made, confirming accurate measurements. Careful preparation of the obturation is considered to be the first step towards curing tooth pain after nerve removed. The second condition is supposed to be the control of filling channels via special techniques. Another step is diagnostics. For this one computer tomography must be run. Then the strategy of curing is developed.
- Non-standard structure of the root system. The root system is complex and not always predictable structure. In some cases, dentists find four channels in three roots. Another option is a non-standard structure branching channels. An essential condition for successful dental treatment is a complete obturation of all channels and their branches. Unfortunately, in some cases the branches are not visible even on the x-ray. This is the case when even an experienced specialist is not immune from errors. The branches left without attention can develop an infection.
- Chip endodontic tool in my tooth. If your tooth still hurts after nerve removed, it may be connected with the tool leftover in your mouth. Very fine endodontic instruments are used for drilling channels and a precise definition of the length. In rare cases, the tip of the tool breaks off, remains in the cavity and becomes the cause of post-sealing pain. This error is diagnosed by the dentist using x-ray examination. To correct the error, the dentin must be bkoken, an unknown body removed and an audit and re-sealing conducted.
- Incomplete removal of carious tisious. If a patient with pulpitis or caries has a toothache after nerve removal, the possible cause may be an incomplete removal of carious tissues. Carious tissue is a source of bacterial microflora, extremely resistant to antibiotics. Successful curing of this ailment with drilling out some affected tissues is the best the doctor can do. Make sure the dentist uses the sanitizer on everything he uses to put in your mouth. Incomplete removal of carious tissue appears to be the most common cause of post-sealing ache. There is a pathogenic microflora in the tooth, the inflammation is developing itself and the painful process extends to healthy parts of the mouth. With poor isolation from saliva before filling or with poor curing of channels, the ache may occur again in a few weeks or even months. Regardless of their intensity, you need to seek help from a dentist, because homemade remedies to cope with the infection will not work. In 99% of cases, the bacteria are resistant even to strong antibiotics, so the effectiveness of rinsing or lotions is very doubtful. The only effective method of treatment is the removal of the seal, the revision of the channels with the use of antiseptics and re-filling them again.
- Incomplete closure of channels. The second reason for post-sealing pain is a mirror image of the previous one. The channel may not be fully sealed. An infection develops, which is why the tooth hurts after the removal of the nerve. The dentist’s mistake can be caused by incorrect estimation of the length of the canal, by the lack of quality control of treatment or by ignoring the unsatisfactory results of this control, which indicate the need for a repeat procedure.
If you have a toothache after dental treatment, do not try to solve the problem yourself. See a specialist. He will diagnose and make an effective treatment plan to eliminate the cause of pain, not to relieve the symptom.
