If you are wondering what is root canal treatment, it is a dental procedure used to treat infection or severe damage inside a tooth and, when clinically appropriate, preserve the natural tooth.
Inside every tooth is a soft tissue called the dental pulp, which contains nerves, blood vessels and connective tissue. Deep decay, cracks, trauma or repeated dental procedures can damage or infect this tissue. Without appropriate treatment, the infection may cause pain, swelling and further damage.
Root canal treatment, also known as endodontic treatment, involves removing the damaged or infected pulp, carefully cleaning and disinfecting the root canals, and sealing them. The tooth is then restored with a filling or, in some cases, a dental crown.
At Dental Solutions Clinic in Indiranagar, Bangalore, treatment decisions should be based on a clinical examination and appropriate diagnostic assessment.

Quick Answer: Root canal treatment is performed to remove infected or damaged tissue from inside a tooth, clean and seal the root canal system, and help preserve the natural tooth.
What Is Root Canal Treatment?
Root canal treatment is a procedure used when the pulp inside a tooth becomes inflamed, infected or severely damaged.
The dentist accesses the inside of the tooth and removes the affected pulp. The root canal system is then cleaned, shaped and disinfected before being filled and sealed.
The primary goals of treatment are to:
- Remove infected or damaged pulp tissue
- Reduce bacterial contamination
- Help control infection
- Preserve the natural tooth when possible
- Restore chewing function
- Reduce the need for tooth extraction
A root canal-treated tooth may subsequently need a permanent restoration, depending on how much natural tooth structure remains.
Why Is Root Canal Treatment Needed?
Root canal treatment may be recommended when bacteria or damage reaches the pulp of the tooth.
Common causes include:
Deep Tooth Decay
Untreated cavities can gradually progress through the outer layers of the tooth and reach the pulp.
Cracked or Fractured Teeth
Cracks can create a pathway for bacteria to enter the inner part of the tooth.
Dental Trauma
An injury to the mouth may damage the pulp even when there is no immediately visible fracture.
Repeated Dental Procedures
Many procedures on the same tooth may sometimes affect the pulp.
Severe Infection
An infection inside the tooth can spread toward the root and surrounding tissues.
Not every painful tooth requires a root canal. A dental examination is necessary to identify the cause and determine the appropriate treatment.
Signs You May Need Root Canal Treatment
Symptoms vary from person to person. Some teeth with significant infection may produce little or no pain.
Possible signs include:
- Persistent toothache
- Severe pain while chewing
- Prolonged sensitivity to hot or cold
- Swelling around the tooth or gums
- Tenderness when biting
- Darkening or discoloration of the tooth
- A recurring gum swelling or pimple
- Facial swelling in more severe cases
If you have significant swelling, fever, difficulty swallowing or breathing, seek urgent medical or dental care.
Root Canal Treatment Procedure: Step by Step
Understanding the procedure can help reduce anxiety before treatment.
Step 1: Dental Examination and Diagnosis
The dentist examines the tooth and reviews your symptoms and dental history.
Diagnostic imaging, such as a dental X-ray, may be used when clinically appropriate to assess:
- The root structure
- Possible infection around the root
- The extent of tooth damage
- Bone changes
- The number and shape of root canals
Step 2: Local Anaesthesia
Local anaesthesia is used to numb the treatment area and improve patient comfort.
You may feel pressure during parts of the procedure, but the dentist aims to control pain throughout treatment.
Step 3: Tooth Isolation
The affected tooth is isolated to help maintain a clean treatment area and reduce contamination.
A dental dam may be used depending on the treatment approach and clinical requirements.
Step 4: Accessing the Dental Pulp
The dentist creates a small opening in the tooth to reach the pulp chamber.
The infected or damaged pulp tissue is then carefully removed.
Step 5: Cleaning the Root Canals
Specialised instruments are used to clean the root canals.
The dentist carefully removes remaining damaged tissue and shapes the canals to prepare them for sealing.
The root canal system may also be irrigated with appropriate disinfecting solutions.
Step 6: Filling and Sealing the Canals
After cleaning and preparing the canals, they are filled with a suitable biocompatible material and sealed.
This helps reduce the risk of bacteria entering the treated canals.
Some complex cases may need treatment over more than one appointment.
Step 7: Restoring the Tooth
After root canal treatment, the tooth is restored.
Depending on the amount of remaining tooth structure, the dentist may recommend:
- A permanent filling
- A dental crown
- Another appropriate restorative option
The final restoration is important because a root canal-treated tooth may become more vulnerable to fracture when significant tooth structure has already been lost.
How Long Does Root Canal Treatment Take?
The duration depends on several factors, including:
- The location of the tooth
- Number of roots and canals
- Complexity of the root anatomy
- Severity of infection
- Whether the treatment is being performed for the first time or as retreatment
A straightforward case may need fewer appointments, while complex cases can take longer.
Your dentist can provide a more accurate timeline after evaluating your tooth.
Is Root Canal Treatment Painful?
Modern root canal treatment is generally performed using local anaesthesia to help keep the patient comfortable.
It is important to understand that the severe pain many patients experience before treatment is often caused by inflammation or infection inside the tooth. Root canal treatment is performed to address the underlying dental problem.
Some tenderness or sensitivity may occur for a few days after treatment.
Contact your dentist if you experience:
- Increasing pain
- Significant swelling
- Persistent discomfort
- A damaged temporary restoration
Benefits of Root Canal Treatment
Helps Preserve the Natural Tooth
When clinically appropriate, saving a natural tooth can help maintain normal function and tooth alignment.
Removes Damaged or Infected Pulp
Treatment addresses infection or irreversible damage within the tooth.
Supports Chewing Function
After appropriate restoration, the tooth may continue to function during normal chewing.
May Prevent Tooth Extraction
Root canal treatment can end the need to remove a tooth in cases where the tooth can be predictably restored.
Root Canal Recovery and Aftercare
Recovery varies according to the condition of the tooth and complexity of treatment.
Aftercare recommendations may include:
- Avoid chewing hard foods on the treated tooth until it is fully restored.
- Take prescribed medication only as directed.
- Brush and floss regularly.
- Attend recommended follow-up appointments.
- Avoid biting hard objects such as ice.
- Get the final restoration completed as advised.
Mild tenderness can occur after treatment. However, severe or worsening symptoms should be discussed with your dentist.
What to Eat After Root Canal Treatment
After a root canal treatment, it is generally best to choose soft and easy-to-chew foods until the numbness wears off and the tooth is comfortable. Your diet after root canal treatment may also depend on whether you have a temporary filling or are waiting for a permanent crown.
Good food options may include:
- Soft rice
- Khichdi
- Idli
- Soft vegetables
- Dal
- Yogurt or curd
- Scrambled eggs
- Soft fruits
- Soups that are not excessively hot
- Oatmeal
- Soft pasta
Try to chew on the opposite side of the treated tooth, especially if you have a temporary filling or your dentist has recommended a permanent crown.
What Not to Eat After Root Canal Treatment
Avoid very hard, sticky or crunchy foods immediately after treatment, particularly before the tooth receives its final restoration.
Examples include:
- Hard nuts
- Ice
- Hard candies
- Sticky sweets
- Popcorn
- Very hard snacks
A root canal-treated tooth may be weaker when significant tooth structure has been lost. Follow your dentist’s instructions about when normal chewing can be resumed.
When Is a Crown Needed After Root Canal Treatment?
Not every root canal-treated tooth requires a crown.
However, a crown may be recommended when:
- A significant amount of tooth structure is missing
- The tooth has large existing fillings
- The tooth is cracked or weakened
- The tooth is subjected to significant chewing forces
Back teeth, such as premolars and molars, may need extra protection because they experience greater biting forces.
Your dentist will recommend the most appropriate restoration based on your individual tooth.
Root Canal Treatment vs Tooth Extraction
| Factor | Root Canal Treatment | Tooth Extraction |
| Natural tooth | Preserved when possible | Removed |
| Main purpose | Treat infection and save the tooth | Remove a tooth that cannot be preserved |
| Tooth replacement | Usually not immediately required | May be recommended |
| Function | Restored using filling or crown | May require implant, bridge or denture |
| Additional procedures | Restoration may be needed | Replacement treatment may be needed |
When a tooth has a reasonable prognosis, preserving it may be an appropriate option. However, extraction may be necessary if the tooth cannot be predictably restored.
A clinical examination is essential before making this decision.
What Happens If You Delay Root Canal Treatment?
Delaying treatment may allow an underlying dental infection or problem to progress.
Possible consequences can include:
- Increasing pain
- Development of an abscess
- Swelling
- Damage to surrounding tissues
- Further loss of tooth structure
- Reduced chances of preserving the tooth
Early assessment can help determine the appropriate treatment before the condition becomes more complex.
When Should You Visit a Dentist in Bangalore?

- Tooth pain
- Sensitivity
- Pain while biting
- Gum swelling
- Tooth discoloration
