Associated symptoms
Root filling as the final step of the root canal treatment can cause accompanying symptoms, which can also result in pain and discomfort. During the treatment itself, the preparation, rinsing and penetration of the files into the root canals can cause sensitivity and slight discomfort. Since very aggressive irrigations are used to disinfect the canal and kill the bacteria during rinsing, unpleasant symptoms often occur.
The penetration of the file into the canal can also cause stinging pain, because when the needle goes beyond the tip of the root, there is again intact nerve tissue, which can hurt when touched. The treating dentist can quickly remedy this by injecting an anaesthetic directly into the canals, which anaesthetizes the tooth directly and thus takes away all discomfort. Furthermore, this type of anaesthesia also has the advantage that only the tooth itself is anaesthetized and hardly any areas and regions around it. Because the tooth is no longer vital during root canal filling, it is quite possible that the patient will not feel any discomfort during the treatment.
Treatment/Therapy
The treatment and the therapy route differ depending on the patient’s situation. The duration of the treatment, the use of rinsing solutions or medicinal inserts, as well as the materials used for the root canal filling vary. In the case of milk teeth, for example, a root filling is only made with absorbable materials such as calcium hydroxide, so that the milk tooth remains as a placeholder and the root with the filling is absorbed by the body when the permanent tooth follows.Heavily gangrenous teeth, in which the nerve has died and has already decayed for some time, a medication is necessary, which has a strong disinfecting and calming effect to remove all bacteria.
The rinsing solutions also vary depending on the situation. In the case of calcified channels, these must be softened with a calcinase solution in order to widen the channels at all. In case of an acute nerve inflammation in a living tooth, an irrigation solution with a strong disinfecting effect is sufficient to treat the canal system. This includes sodium hypochloride, for example. In vital teeth with an inflammation, the root canal filling can still take place in the same or the next session, whereas in devital, gangrenous teeth, several drug inserts and rinses are often necessary to seal the tooth.
