What is Root Canal treatment?
Root Canal Treatment (RCT), also known as endodontic treatment, is a dental procedure performed to treat an infected or damaged tooth while preserving the natural tooth. During the treatment, the infected pulp inside the tooth is removed, the root canals are thoroughly cleaned, disinfected and sealed to prevent further infection. This helps to relieve pain, restore the tooth’s function and avoid the need for extraction.
Root canal treatment is one of the most effective ways to save a natural tooth affected by infection. With modern dental techniques, the procedure is comfortable, reliable and designed to restore both oral health and normal chewing function.
Need for Root Canal Treatment
Root canal treatment is recommended when the pulp inside the tooth becomes inflamed or infected. This can happen due to deep tooth decay, repeated dental procedures, cracks, chips or injuries that affect the inner portion of the tooth. If the infection is left untreated, it may lead to severe pain or formation of a dental abscess.
The purpose of root canal treatment is to remove the infection while preserving the natural tooth. Saving the tooth helps to maintain normal biting function and eliminates the need for tooth extraction. Depending on the condition of the tooth, the procedure may be performed by a general dentist or an endodontist.
Intentional Root Canal treatment
In certain situations, a root canal treatment may be recommended even before symptoms appear. This is known as an intentional root canal treatment.
It is commonly advised when a tooth requires significant trimming for procedures such as a dental bridge or when the tooth has deep decay or multiple fillings. Performing the treatment in advance helps to reduce the risk of future infection and severe sensitivity after the restorative treatment is completed.
Single Sitting Root Canal treatment
Many root canal treatments can be completed in a single appointment, making the procedure more convenient while reducing the number of dental visits and overall healing time.
However, some cases may require multiple appointments, when the infection is extensive or the tooth has a complex root canal structure. The number of visits depends on the condition of the tooth and the complexity of the treatment.
The procedure generally includes:
- Removal of infected pulp: The infected or inflamed tissue is carefully removed from the tooth.
- Cleaning and disinfection: The root canals are cleaned, shaped and disinfected.
- Filling and sealing: The canals are filled with a suitable material and sealed to help prevent reinfection.
- Final restoration: The tooth is restored with a filling. A dental crown may also be recommended to provide additional strength and protection.
Painless Root Canal treatment
Painless Root Canal treatment is performed under local anaesthesia to numb the affected tooth and the surrounding area, helping to minimise discomfort during the procedure. Modern techniques and equipment allow the treatment to be carried out with greater precision and patient comfort.
For patients who experience dental anxiety, sedation options may also be recommended when required. After the procedure, medications and post-treatment instructions are provided to support the healing process and ensure a comfortable recovery.
Repeat Root Canal treatment
Although root canal treatment is a successful procedure, some teeth may require repeat root canal treatment if the infection persists or recurs. The procedure involves removing the existing filling material, cleaning the root canals again and resealing them to help preserve the natural tooth.
Repeat root canal treatment may be recommended in the following situations:
- Persistent infection: The tooth does not heal completely after the initial treatment.
- Reinfection: Bacteria enter the root canals due to leakage or damage to the restoration.
- Missed canals: Additional root canals that were not treated during the first procedure require further treatment.
- Damaged restoration: A loose or damaged filling or crown allows bacteria to reach the root canals.
Steps in Repeat Root Canal Treatment
The procedure generally includes:
- Diagnosis: The dentist examines the tooth and may recommend dental X-rays to evaluate the condition of the tooth and surrounding tissues.
- Local anaesthesia: The treatment area is numbed before the procedure begins.
- Access to the tooth: The existing filling or crown is removed to reach the root canals.
- Cleaning and disinfection: The previous filling material is removed and the root canals are cleaned and disinfected again.
- Refilling the canals: The cleaned canals are sealed with a biocompatible filling material to prevent further infection.
- Sealing the tooth: The access opening is sealed with a temporary or permanent filling.
- Final restoration: A dental crown or other suitable restoration may be recommended to protect the treated tooth.
Aftercare
The aftercare for repeat root canal treatment is similar to that of the initial procedure.
- Maintaining good oral hygiene.
- Monitoring the treated tooth
- Attending follow-up appointments help support proper healing.
If you notice persistent pain, swelling or any unusual symptoms after the procedure, consult your dentist for further evaluation.
Benefits of Root Canal treatment
- Relieves pain by removing the infected pulp.
- Removes the source of infection and helps prevent it from spreading.
- Reduces the risk of dental abscess by eliminating infected tissue.
- Preserves the natural tooth and reduces the need for extraction.
- Maintains natural biting force and chewing efficiency.
- Protects neighbouring teeth by preventing unnecessary strain.
- Reduces the need for tooth replacement by saving the affected tooth.
Steps in Root Canal treatment
Root canal treatment is performed in a series of carefully planned steps to remove the infection and preserve the natural tooth. The procedure generally includes:
- Examination and diagnosis: The affected tooth is examined and dental X-rays may be taken to assess the extent of the infection.
- Local anaesthesia: The tooth and the surrounding area is numbed to ensure a comfortable procedure.
- Isolation of the tooth: A rubber dam is placed around the tooth to keep the treatment area clean and dry.
- Cleaning the root canals: A small opening is created to remove the infected pulp. The root canals are then cleaned, shaped and disinfected.
- Sealing the canals: The cleaned root canals are filled with a suitable material and sealed to help prevent reinfection.
- Final restoration: The tooth is restored with a filling, and a dental crown may be recommended when additional protection is required.
Precautions after treatment
Proper care after root canal treatment supports the healing process and helps protect the treated tooth. Following your dentist’s advice and maintaining good oral hygiene play an important role in a successful recovery.
After the procedure, it is recommended to:
- Avoid chewing on the treated tooth until the numbness wears off and the permanent restoration is completed.
- Take prescribed medications as directed by your dentist.
- Maintain good oral hygiene by brushing and flossing regularly.
- Attend follow-up appointments to monitor healing and complete the treatment if required.
- Consult your dentist if you experience persistent pain, swelling or any unusual discomfort.
Cost of Root Canal Treatment
The cost of root canal treatment starts from ₹4,000. The final treatment cost may vary depending on the individual treatment requirements.
