Quick answer. Root canal (endodontic) treatment removes infected or inflamed pulp from inside a tooth, then cleans, disinfects, fills and seals the canals to save a tooth that would otherwise need extraction. It is done under local anaesthetic, relieves pain, and is generally no more painful than a filling. A protective crown is usually recommended afterwards, which adds to the cost. Fees vary by tooth – molars cost more than front teeth – plus the crown. Routine dental care is not MediSave-claimable, but CHAS subsidies (and, from mid-2026, extended Flexi-MediSave for eligible seniors) help reduce costs. See a dentist promptly for persistent toothache, sensitivity or swelling.

A bad toothache, lingering sensitivity to hot or cold, or swelling around a tooth can signal that the pulp inside it is infected or inflamed. Root canal treatment is the procedure dentists use to clean out that pulp and save the tooth, rather than pulling it out. This guide explains what root canal treatment involves, why the “very painful” reputation is largely a myth, what it typically costs in Singapore, and how it compares with extraction and tooth replacement.
At a glance
| Tooth / item | Typical cost range | Notes |
|---|---|---|
| Front tooth (anterior) | ~$400 – $775 | Single canal; usually the least complex and lowest cost |
| Premolar | ~$500 – $900 | More canals than front teeth |
| Molar | ~$872 – $1,400 | Most complex (multiple canals); generally the costliest |
| Permanent crown (after treatment) | ~$750 – $1,400 | Usually recommended to protect the tooth; a separate, additional cost |
| Public institution (e.g. polyclinic / NDCS) | From ~$329 (subsidised) | Subsidised rates for eligible patients; varies by tooth and facility |
| Extraction (alternative) | ~$100 – $400 | Cheaper upfront but loses the tooth; replacement (implant/bridge/denture) usually costs much more |
What is root canal treatment?
Inside every tooth, beneath the hard enamel and dentine, is a soft tissue called the pulp – it contains the blood vessels and nerves that run from the crown down to the tips of the roots. When this pulp becomes infected or inflamed, it can cause pain and, if left untreated, an abscess.
Root canal treatment (also called endodontic treatment) removes the diseased pulp, cleans and disinfects the empty canals, then fills and seals them. According to the National Dental Centre Singapore (NDCS), the aim is to conserve teeth that will otherwise have to be extracted. After treatment the tooth is pulpless but the surrounding gum, ligament and bone remain alive, so the tooth can continue to function normally with good oral hygiene.
Why might you need it?
The pulp can be damaged or infected by:
- Deep decay that reaches the pulp
- A cracked or fractured tooth
- Repeated dental work or large fillings on the same tooth
- Trauma to the tooth
Common warning signs include severe or persistent toothache, prolonged sensitivity to hot or cold, pain on biting, swelling of the gum or face, or a darkening tooth. These symptoms mean you should see a dentist promptly – an untreated infection can spread and may lead to losing the tooth.
Does it hurt? Dispelling the myth
Root canal treatment has an outdated reputation for being extremely painful. In reality, it is carried out under local anaesthetic, so the procedure itself is generally no more uncomfortable than having a filling. NDCS describes modern root canal treatment as relatively comfortable and often painless.
Far from causing pain, the treatment usually relieves the toothache caused by the infected pulp. Some mild tenderness afterwards is normal and typically settles with over-the-counter pain relief.
The process and aftercare
A dentist first numbs the area, then isolates the tooth with a rubber dam. An access opening is made, the canals are cleaned with fine instruments while being flushed with an antibacterial solution, and finally sealed (usually with a rubber-like material called gutta-percha). NDCS notes treatment may be done in single or multiple visits depending on tooth complexity – commonly one to two visits.
Because a root-treated tooth can become brittle, a crown is usually recommended afterwards to protect it from fracture under biting forces. This is a separate, additional cost. Success rates are high: NDCS states that most endodontically-treated teeth last as long as natural teeth once a permanent restoration is placed and good oral hygiene is maintained.
How much does it cost in Singapore?
Cost depends mainly on which tooth is involved – molars have more canals and are more complex, so they cost more than front teeth. Treatment may be done by a general dentist (GP dentist) or by an endodontist (a root canal specialist), with specialist and complex cases typically costing more. Polyclinics and NDCS offer subsidised care for eligible patients.
The figures below are typical ranges based on MOH’s published CHAS fee benchmarks for private clinics; your actual fee depends on the clinic, complexity, and whether a crown is needed. Remember to add the cost of the crown, which is usually recommended afterwards.
Financing: MediSave, CHAS and the extraction alternative
MediSave: Routine dental treatment such as a standard root canal is generally not MediSave-claimable. (A separate Flexi-MediSave allowance of up to $400/year is being extended from mid-2026 to cover root canals and permanent crowns for eligible seniors aged 60+ at accredited CHAS clinics and public institutions.)
CHAS: Community Health Assist Scheme cardholders (Blue, Orange, Pioneer and Merdeka Generation) receive subsidies for restorative procedures including root canal treatment at participating clinics. From October 2025, MOH raised subsidy limits for several tooth-saving procedures. Note that for multi-visit treatments, subsidies are claimed after the procedure is completed.
The alternative – extraction: Pulling the tooth is cheaper upfront (around $100-$400), but a missing tooth usually needs replacing with an implant, bridge or denture, which is often far costlier overall – and you lose the natural tooth. Implants can run several thousand dollars per tooth. For most patients, saving the natural tooth with root canal treatment is the more cost-effective long-term choice.
