01
Persistent Toothache
Ongoing or spontaneous tooth pain can be associated with inflammation or infection inside the tooth.
Root Canal Treatment
Understanding the Root Canal Treatment Process
Root canal treatment, also known as RCT or endodontic treatment, is performed to treat infection or inflammation inside a tooth. The aim is to remove the affected pulp, clean and disinfect the root canal system, and seal the tooth so it can be restored.
When a tooth can be saved, root canal treatment may help preserve your natural tooth rather than removing it. Your dentist will first assess the condition of the tooth and explain the most appropriate treatment options.
- Examination of the affected tooth
- Dental X-rays when clinically indicated
- Removal of inflamed or infected pulp
- Cleaning, shaping, and sealing of root canals
- Planning the final filling or crown
The number of visits and the type of final restoration
depend on the tooth, the extent of infection, and the
complexity of the root canal system.
Root canal treatment focuses on cleaning and sealing the inside of a tooth to help preserve it.
Step One
When Might You Need an RCT?
Damage or infection inside a tooth can develop for several reasons. Your dentist examines the tooth, reviews your symptoms, and may take X-rays or perform other tests to determine whether root canal treatment is appropriate.
02
Sensitivity to Hot or Cold
Lingering sensitivity may indicate pulp inflammation, although examination is needed to establish the cause.
03
Deep Tooth Decay
Extensive decay can reach the pulp inside the tooth and may require root canal treatment.
04
Cracked or Damaged Tooth
A crack, fracture, or dental injury can damage the pulp even when the tooth still looks intact.
05
Swelling Near the Tooth
Gum swelling, a pimple-like bump, or drainage near a tooth may indicate infection requiring assessment.
06
Darkening of a Tooth
A tooth that changes colour may have several causes, including previous trauma or pulp damage.
Do not ignore dental swelling.
Facial swelling, fever, or rapidly worsening pain requires
prompt dental assessment. Difficulty breathing or swallowing,
or rapidly spreading swelling, requires emergency medical care.
Step Two
Examination and Treatment Planning
Before starting treatment, the dentist evaluates the affected tooth and the tissues around it. This helps determine whether the tooth is suitable for root canal treatment and what restoration may be needed afterward.
- Review of symptoms and dental history
- Examination of the tooth and surrounding gums
- Assessment of tenderness and tooth condition
- Dental X-rays when appropriate
- Discussion of treatment stages and alternatives
Why Is Diagnosis Important?
Tooth pain can have different causes. An examination helps identify the source of the problem and whether RCT, another treatment, or extraction should be considered.
Your dentist will also assess whether enough healthy tooth structure remains to restore the tooth after treatment.
Personalised Treatment Plan
Front teeth, premolars, and molars can have different numbers and shapes of root canals. Complex cases may require additional time, appointments, or referral to a root canal specialist.
The root canal system is cleaned, disinfected, and sealed as part of endodontic treatment.
Step Three
How Is Root Canal Treatment Performed?
RCT is generally performed under local anaesthesia to numb the tooth and surrounding area. A protective isolation method is commonly used to keep the treatment area clean during the procedure.
The dentist then accesses the inside of the tooth, removes the affected pulp, and carefully cleans and shapes the root canals.
- The tooth is numbed and isolated
- An opening is made to reach the pulp chamber
- Inflamed or infected pulp is removed
- The root canals are cleaned and disinfected
- The canals are filled and sealed when ready
Depending on the complexity and condition of the tooth,
the procedure may be completed in one visit or require
multiple appointments. A temporary filling may be used
between visits.
The Treatment Journey
Root Canal Treatment: Step by Step
Each stage has a specific purpose, from controlling discomfort to sealing the cleaned canal system and protecting the treated tooth.
01
Local Anaesthesia
The affected area is numbed to help make the procedure more comfortable. Tell your dentist if you feel discomfort.
02
Tooth Isolation
The tooth is isolated to help keep the treatment area clean and protect it from saliva contamination.
03
Access Opening
A small opening provides access to the pulp chamber and the root canals inside the tooth.
04
Cleaning and Shaping
Fine instruments are used to remove affected pulp, shape the canals, and prepare them for disinfection.
05
Canal Disinfection
Suitable irrigating solutions are used to help clean the canal system and reduce microbial contamination.
06
Filling and Sealing
Once ready, the canals are filled with a suitable material and sealed to help prevent reinfection.
Step Four
Final Filling or Dental Crown
After the root canals have been treated, the tooth needs a suitable final restoration to seal the access opening and restore function.
The choice between a filling, onlay, or crown depends on how much healthy tooth structure remains, the position of the tooth, and the forces it experiences during chewing.
- Assessment of remaining tooth structure
- Selection of an appropriate restoration
- Checking the bite and fit
- Instructions for protecting the treated tooth
- Follow-up reviews when recommended
A crown is often recommended for teeth that have lost
substantial structure, particularly many back teeth.
Your dentist will determine the most appropriate
restoration for your specific tooth.
Appropriate restoration helps protect the treated tooth and restore chewing function.
Why RCT May Be Recommended
Potential Benefits of Root Canal Treatment
When a tooth is suitable for treatment, RCT may help manage infection while preserving the natural tooth. The outcome depends on the tooth's condition, treatment complexity, and quality of the final restoration.
Preserves the Natural Tooth
Treatment may allow a tooth to remain in place instead of being extracted when it can be predictably restored.
Helps Address Infection
Removing affected pulp and cleaning the canals helps manage infection inside the tooth.
Aims to Relieve Tooth Pain
Treating the cause of pulpal pain can help relieve symptoms, although recovery varies by case.
Restores Chewing Function
A suitably restored tooth can often be used for everyday chewing after treatment and recovery.
Supports Your Natural Smile
Keeping a restorable natural tooth may avoid the need for immediate tooth replacement.
Works With Long-Term Care
Good oral hygiene, appropriate restoration, and regular dental reviews help maintain the treated tooth.
Root canal treatment does not guarantee that a tooth will last indefinitely. Some teeth may require retreatment, surgery, or extraction if healing does not occur or the tooth cannot be restored successfully.
After Your Treatment
Care After Root Canal Treatment
The tooth and surrounding tissues may feel tender for a short period after treatment. Follow your dentist's instructions and protect the tooth until the final restoration is completed.
Be Careful While Numb
Avoid chewing or consuming very hot foods until the local anaesthesia has worn off.
Avoid Excessive Pressure
Avoid hard or sticky foods on the treated tooth, especially while a temporary filling is present.
Maintain Oral Hygiene
Continue brushing and cleaning between your teeth carefully, following any specific instructions.
Use Medication as Directed
Follow your dentist's advice about any recommended or prescribed pain relief or medication.
Complete the Restoration
Attend the recommended appointment for your permanent filling, crown, or other restoration.
Attend Follow-Up Visits
Your dentist may recommend review appointments to assess symptoms and the condition of the tooth.
Contact your dentist if pain becomes severe or worsens, swelling
develops or increases, your bite feels uneven, or a temporary
filling comes out. Seek urgent care for significant facial
swelling or difficulty breathing or swallowing.
Patient Questions
Frequently Asked Questions About RCT
Find answers to common questions about root canal treatment, appointments, discomfort, and recovery.
Is root canal treatment painful?
Local anaesthesia is generally used to numb the treatment area. Many patients tolerate the procedure well, although tenderness may occur afterward. Tell your dentist if you experience discomfort during treatment.
How many appointments are needed for RCT?
Some root canals can be completed in one visit, while others require two or more appointments. The number depends on the tooth, infection, canal anatomy, and complexity of treatment.
How long does a root canal appointment take?
Appointment length varies according to the tooth and the complexity of the procedure. Your dentist can provide an estimate after examination.
Will I need a crown after root canal treatment?
Not every tooth requires a crown. However, a crown or another protective restoration is often recommended when a tooth has lost substantial structure. Your dentist will assess what is appropriate.
Can a root canal-treated tooth get infected again?
Yes. Reinfection or persistent disease can occur in some cases. Appropriate canal sealing, a good final restoration, oral hygiene, and follow-up care help reduce risks but cannot eliminate them completely.
Can I eat after RCT?
Follow the instructions provided by your dentist. Avoid chewing while your mouth is numb and be cautious with hard foods until the tooth has received its recommended final restoration.
Is it better to save the tooth or extract it?
If the tooth can be predictably treated and restored, preserving it may be a suitable option. Extraction may be necessary for some severely damaged teeth. Your dentist can explain the benefits, risks, and alternatives for your particular situation.
