【Major points】
  1. Pulp extirpation of the tooth is what we called root canal treatment.
  2. When there’s pain or inflammation due to pulpal etiology, dentists will perform root canal treatment.
  3. Pain and swelling may occur 3-7 days following root canal treatment. Please follow prescription for medication.
  4. Avoid biting on hard food with the tooth under treatment, or the risk of tooth fracture may increase.
  5. After the root canal treatment is complete, regular follow up is necessary.

What is root canal treatment?
In order to preserve the tooth with endodontic diseases, we must remove necrotic or inflamed pulp tissue, clean up root canal system, and prevent secondary infection.
 
When do we need root canal treatment?
  1. Acute pulpal disease, manifesting as severe spontaneous pain or gingiva swelling.
  2. Teeth with huge cavity filled undergo discomfort or pain after 2 weeks.
  3. Presence of a gum boil, diagnosed as chronic pulpal disease.
  4. An asymptomatic tooth requires post/core for restoration purposes.
 
Precautions for root canal treatment
Patients with drug allergy, congenital or rheumatic heart diseases, valve defect/repair, hypertension, DM, immune diseases, hematological diseases, hepatitis B, or any other contagious diseases should inform the dentists in advance.
 
Procedures of root canal treatment:
  1. Local anesthesia: dentists will evaluate the condition for injection when needed.
  2. Access cavity: removal of previous restoration and caries with burs.
  3. Debridement: removal of necrotic pulp tissue, irrigation, reduce of bacteria and infection.
  4. Medication with temporary filling: temporary filling is necessary between appointments for infection control.
  5. Obturation: after the root canal system is clean, obturation is performed to seal the root canal.
  6. Crown (restoration): Crowns are recommended for teeth after root canal treatment to restore occlusal function and morphology as well as protect the teeth from fracture.
  7. Microscopic-assisted endodontic treatment may be introduced depending on the complexity of root canal system for better treatment outcome. (additional fee)

Post-treatment instructions:
  1. Pain and swelling may occur 3-7 days following root canal treatment. Please follow prescription for medication.
  2. If pain and swelling continued, please contact your dentist.
  3. Avoid biting on hard food with the tooth under treatment, or the risk of tooth fracture may increase.
  4. With the lesion extending to periapical area, long-term follow up is suggested.
  5. Do practice good oral hygiene.
  6. Regular follow up.
