When the gum tissue of a tooth is attacked by bacteria or bacterial toxins, the doctor will recommend that you undergo a “root canal”. In this case, root canal treatment is the only treatment option.
The surface of the tooth is the hardest tissue in the body, but inside the tooth is a cavity filled with blood vessels, nerves, lymphatic vessels and other soft tissues. This cavity is divided into two parts: the pulp chamber and the root canal, which contains blood vessels, nerves and other tissues called the pulp.
”Root canal treatment is to remove all the pulp tissue under local anesthesia, clean the pulp chamber and root canal thoroughly, fill the pulp chamber and root canal with medical materials, and finally restore the tooth shape.
If you have any of the following conditions, you will need root canal treatment
The tooth is naturally painful or tingles when biting into food
Sore teeth when eating hot or cold foods
Very severe tooth decay or crown damage causing an apical abscess (infection of the alveolar bone)
Pre-operative evaluation
The evaluation should include two aspects, one is the assessment of the affected tooth and the patient, including the selection of indications, the presence of contraindications, the patient’s willingness to treat, the cost issue, and the patient’s kindness index; the second aspect is the assessment of the operator’s own operational feasibility in combination with the affected tooth.

The process of root canal treatment.
Step 1.
Under local anesthesia, some of the hard tissue of the crown is ground away and the pulp chamber is opened.
(digital x-ray)
Step 2.
Removal of pulpal tissue (using a Densberg-Root Canalometer).
Step Three.
Enlargement and cleaning of the root canal (using a Densberg-PROTAPER root canal file), followed by placement of the medication
Step four.
Fill the root canal with a permanent material and repair the crown.
Step 5.
Staking the root canal and then a porcelain or all-ceramic crown is placed to protect the tooth.
The success rate of root canal treatment is clinically reported to be over 90% and is currently the best treatment to preserve the affected tooth.
In general, root canal treatment is suitable for pulpitis, pulp necrosis, and all types of periapical inflammation.
In particular, root canal therapy is the only treatment option for teeth with residual crowns that require pile crown restoration in the prosthodontics department.
