What is RCT?

RCT, (full name Root Canal Therapy), also known as endodontics, it is a surgery in dentistry to treat pulp necrosis and tooth root infection. For tooth decay that cannot be repaired by ordinary fillings, root canal therapy can preserve the natural tooth as much as possible, so it is complementary to tooth extraction.

Situations that require root canal therapy

1. Pulpitis

The pulp of the tooth becomes inflamed from a bacterial infection. In the sealed pulp cavity, the pulp is not usually infected by bacteria, but when the tooth is perforated by caries, external bacteria can invade the pulp cavity and infect the pulp.

2. Periapical periodontitis

After the dental pulp is infected with bacteria, the bacteria will invade the alveolar bone through the apical foramen, causing inflammation of the periapical tissue. The infected pulp must be removed before the periapical periodontitis can be cured.

3. Pulp exposure

Fracture or splitting of the crown due to trauma, or abrasion of the deformed central cusp (the conical protrusion at the central fossa on the chewing surface of the tooth), resulting in exposure of the pulp. Once the pulp is exposed, it is about to become infected and a root canal is also required treat.

4. Crown restoration

In principle, it is necessary to preserve the living healthy pulp as much as possible, but individual teeth are deviated and twisted, but cannot be corrected due to various reasons, and a full crown restoration is required, which will damage the pulp during tooth preparation. At this time, it is also necessary do root canal therapy.

5. Cracked tooth

There are cracks in the tooth, which penetrate deep into the pulp cavity, and bacteria enter the pulp, and root canal therapy is also required.

6. Special cases

Some systemic diseases are not suitable for tooth extraction, but those who need to keep the affected teeth through therapy can also choose root canal therapy.

Is root canal therapy really painful?

Usually, the nerve of the tooth that needs root canal therapy has been necrotic, so there will be no severe pain during the therapy. If you are more afraid of pain, you can communicate with the doctor for local anesthesia.

In addition, root canal therapy requires multiple visits to the doctor. There may be postoperative reactions during the consultation and after surgery, and pain and discomfort may occur, but usually it will pass in about 2-3 days. Swelling or pain occurs only when very few patients respond significantly to the commonly used root canal disinfection drugs in clinical practice.
