The process of killing the nerve of a tooth, also known as root canal treatment, is divided into three main steps, which are root canal preparation, root canal disinfection and dressing change, and root canal filling.
1. Root canal preparation: open the pulp cavity, remove the pulp cleanly, and use a root canal file to prepare the root canal, so that the root canal forms a smooth pathway.
2. Root canal disinfection and dressing change: After root expansion, root canals are disinfected and dressed with commonly used medications such as camphor phenol, formaldehyde cresol, calcium hydroxide, etc. Depending on the degree of inflammation in the root canals, the canals may need to be sealed for 1~2 weeks.
3. Root canal filling: wait until the tooth has no obvious knocking pain, no obvious inflammation oozing out of the root tip, and when the temporary sealing cotton twist is dry, then carry out root canal filling.
It is best to kill the nerve of the tooth to the regular hospital into the better, conducive to the success of root canal treatment.
