The general steps of endodontics treatment

endodontics treatment steps

Remove the carious tissue of the tooth,expose the pulp cavity,and extract the infected pulp with a root canal pulp needle (this is also the source of the term “tooth extraction nerve”).
Measure the length of the root canal.Because the teeth are opaque,some instruments must be used to measure the length of the root canal.Nowadays,root canal length measuring instruments are generally used for measurement.
Use a dental rotory files to prepare the shape of the root canal,that is,to remove dirt on the root canal.With the advancement of technology,it has progressed from traditional hand instruments to mechanical methods.On the one hand,it can improve the quality of root canal preparation, and on the other hand,it will shorten the treatment time and make the experience of patients and doctors better.
While preparing the root canal,but also constantly washing the root canal,more and more doctors are beginning to use ultrasonic instruments to wash the root canal to ensure the cleanliness of the root canal.

After the preparation of the root canal is completed,according to the difference of the disease,it is necessary to seal the disinfectant in the root canal,and return to the clinic after a period of time.

At the follow-up visit,the original medicine is taken out,the root canal is sealed with a permanent material,and finally the shape of the tooth is restored.If necessary,a fixed restoration should be made.

Many patients do not understand why after the root canal treatment,the tooth no longer hurts, and it is enough to repair it. Why should a full tooth crowns protection be needed?In fact,this step is necessary for three main reasons.


  1. Root canal endodontics treatment is to remove and disinfect the residue and bacteria in the root canal as much as possible through the operation of drugs and instruments.However,if such a disinfection process is to be carried out carefully,many teeth infected by bacteria and tooth tissues that have to be trimmed must be removed.Therefore,once endodontic treatment is applied to most teeth,they may not have enough strength to support chewing and may break.It is impossible to restore function by using materials alone,even if the long-term effect can be restored.

2. After root canal endodontics treatment,the tooth loses the nutrient supply from the pulp,just like a tree that loses its root,it slowly withers and becomes very fragile,causing the fragility of the tooth to increase and it is easy to split.

  1. Because the teeth that need endodontics treatment are generally decayed (worm teeth) and have large defects.Although the root canal treatment is completed at this time,the remaining tooth tissue is very fragile,and it is very easy to break and split.It loses its normal function,and it is no longer possible to restore the function by simply using materials.
