TL;DR
- A root canal is a dental treatment that cleans out infection inside a tooth and helps save it.
- Contrary to popular belief, the procedure is not painful because local anaesthesia will be administered beforehand.
- Most patients recover quickly, often returning to normal activities the next day with only mild, temporary soreness.
Root canal treatment (RCT) may sound intimidating, but in reality, it’s a routine procedure dentists use to save teeth that might otherwise need to be removed.
In this guide, we’ll walk you through why it’s needed, how it works, what to expect during recovery, and how to avoid one in the future.
Why You Might Need a Root Canal Treatment
So, what is a root canal? It’s the natural cavity inside your tooth that houses the pulp, which is a bundle of nerves, blood vessels, and connective tissue that keeps the tooth alive.
When this pulp becomes inflamed or infected, root canal treatment may be required to save the tooth instead of removing it.
What causes root canal problems? Here are the most common ones:
- Deep decay that reaches the pulp.
- A cracked or fractured tooth.
- Repeated dental procedures on the same tooth.
- Trauma, such as an injury that damages the pulp, can occur even without visible cracks.
Left untreated, pulp infection can spread, causing an abscess, severe pain, and eventually tooth loss.
If you’re experiencing tooth pain or swelling, book a dental check-up at Newlife Dental Practice to catch problems early and avoid more complex treatment later.
Symptoms of a Root Canal Treatment
The signs that you may need a root canal treatment aren’t always obvious at first. But often, the symptoms include:
- Persistent Toothache: Pain that lingers, throbs, worsens when chewing or applying pressure, or even flares up at night (nocturnal pain).
- Prolonged Sensitivity: Sharp or lingering discomfort when eating hot, cold, or sweet foods.
- Swelling and Tenderness: Gums around the affected tooth may appear red, swollen, or tender to the touch.
- Darkening of the Tooth: An infected pulp can cause the tooth to appear darker or discoloured compared to neighbouring teeth.
- Pimple-Like Bump on Gums: Sometimes a small pus-filled swelling (dental abscess) forms near the tooth.
These symptoms don’t always appear at the same time, but any combination of them should prompt a dental check-up. Early treatment often means a less invasive process and a better chance of saving your natural tooth.
Is Root Canal Treatment Painful?
No, root canal treatment itself isn’t usually painful because the area is numbed with local anaesthesia. Any discomfort is usually from the infection beforehand, not the procedure. In fact, most patients feel relief once the diseased pulp is removed.
How the Root Canal Procedure Works
- Diagnosis: To confirm if a root canal is needed, your dentist will first examine your tooth, often with an X-ray. This helps to check if the pulp is infected or damaged.
- Anaesthesia: Local anaesthesia numbs the area so you stay comfortable throughout the root canal treatment.
- Pulp Removal: Your dentist will then make a small opening in the tooth and remove the infected or dead pulp tissue.
- Cleaning & Disinfection: The inside of the root canals will be shaped, cleaned, and disinfected to remove bacteria.
- Sealing the Tooth: The canals will be filled with a biocompatible material (usually gutta-percha) and sealed to prevent reinfection.
Now you may be asking: How long does a root canal take? It may be completed in one visit or spread over multiple sessions, depending on the severity of your condition.
Single vs Multi-Visit Treatment
- Single Visit (1–2 hours): Suitable for when the infection is mild and the root canals can be cleaned and sealed in one session.
- Multi-Visit (2–3 shorter sessions): Recommended if the root canals are curved or complex, if there is significant infection, or if additional time is needed for thorough disinfection before sealing.
Root Canal Treatment Cost in Singapore & Medisave Eligibility
The cost of a root canal treatment in Singapore varies depending on which tooth is affected and how complex the procedure is.
Estimated cost ranges for a root canal treatment in Singapore:
- Front tooth: $300-$700
- Premolar: $500-$900
- Molar: $800-$1,500
Note: These ranges are general estimates from MOH and may not reflect the exact charges at every clinic.
Other factors that may affect the cost of a root canal include:
- The severity of infection and whether multiple visits are required.
- The type of dental clinic (private vs subsidised).
- Additional treatments, such as a crown placed after the root canal, may be necessary.
Can You Use Medisave for a Root Canal Treatment?
Medisave typically doesn’t cover routine non-surgical root canal procedures. However, surgical endodontic treatments (such as apicoectomy, a minor surgery at the root tip) may be eligible. Contact us here to get clarity on our claim policies.
Recovery, MC, and Aftercare
Most patients are able to resume normal activities the following day of their root canal treatment. And though mild soreness and/or sensitivity may linger for a short period, they usually subside on their own.
How Many Days Medical Claim (MC) Can I Get for a Root Canal?
Dentists typically issue one day of MC, though more may be given if there’s swelling or an abscess.
Aftercare Tips Post-Root Canal Treatment
- Avoid chewing on hard foods with the treated tooth until a crown is fitted.
- Maintain daily brushing and flossing to prevent reinfection.
- Keep up with scheduled follow-ups so your dentist can track your healing and reinforce the tooth if needed.
Why a Crown Is Important After a Root Canal
After a root canal treatment, your tooth typically loses some of its natural strength and becomes more likely to crack. Without added protection, everyday chewing can place stress on the tooth, increasing the risk of fractures.
That’s why most dentists recommend a dental crown after root canal treatment, as it helps restore the tooth’s strength and protects against reinfection.
So, how long does a root canal last without a crown? In most cases, not as long as one that’s been properly reinforced.
Side Effects of a Root Canal Treatment & When Problems Can Reoccur
Most root canal treatment side effects are short-term and usually improve on their own:
- Mild soreness around the tooth
- Tenderness when chewing
- Temporary sensitivity
In rare cases, problems can reappear later on:
- Reinfection if bacteria re-enter the canal
- Cracked root or tooth
- Worn or leaking crown/filling that allows decay back in
If pain or swelling comes back years later, the tooth may need to be re-examined.
How to Avoid a Root Canal in the First Place
You can lower your chances of needing a root canal by:
- Brushing your teeth twice a day and flossing daily to prevent cavities from reaching the pulp.
- Treating small cavities before they spread.
- Wearing a mouthguard when playing sports.
- Avoid chewing hard items like ice or nutshells that can crack teeth.
When to See a Root Canal Specialist in Singapore
See a dentist right away if you notice:
- Persistent toothache.
- Swelling or pus around the tooth.
- Sensitivity that doesn’t go away.
General dentists may refer you to an endodontist (a root canal specialist) if the root canals are complex, a previous root canal needs retreatment, or surgical endodontics is required.
Final Takeaway
A root canal treatment may sound intimidating, but with modern techniques and anaesthesia, it’s often no more uncomfortable than a regular filling. More importantly, it’s a proven way to stop infection, relieve pain, and preserve your natural tooth for many years.
