When a tooth hurts persistently, wakes you at night, or has become sensitive to heat that doesn’t resolve quickly, the problem is almost certainly inside the tooth — in the pulp, the living tissue that occupies the chamber at the core of every tooth and extends down into the root canals. Endodontics is the dental specialty dedicated to diagnosing and treating diseases and injuries of the dental pulp and the tissues surrounding the root. At Al Safwa Medical Center in Bani Yas, Abu Dhabi, the endodontics department provides the full range of root canal and pulp treatments — with the goal of preserving natural teeth that would otherwise require extraction.
This guide covers what endodontic treatment involves, when it is needed, how each procedure works, and what recovery looks like. If you have already been told you need a root canal and want specific information on the procedure, the dedicated guide to root canal treatment in Abu Dhabi and the root canal cost guide provide detailed information.
What is endodontics and what does it treat?
The dental pulp is the soft tissue inside the tooth — containing nerves, blood vessels, and connective tissue — that was essential during tooth development but is not necessary for the tooth’s survival once it is fully formed. When the pulp becomes inflamed or infected — through deep decay, a crack, repeated dental procedures, or trauma — it causes significant pain and, left untreated, leads to abscess formation and eventual bone loss around the root tip.
Endodontic treatment removes the diseased or damaged pulp tissue, cleans and shapes the root canals, and seals the system to prevent reinfection — all while preserving the natural tooth structure. This is always preferable to extraction where clinically feasible: a natural tooth, even one that has been root-canal-treated, maintains the jawbone, supports neighbouring teeth, and functions better than any replacement option available. The detailed clinical guide to root canal treatment in Abu Dhabi covers the procedure comprehensively.
Symptoms that indicate endodontic treatment is needed
Not all dental pain requires root canal treatment — but certain patterns of pain and other symptoms are strongly associated with pulpal involvement:
- Spontaneous toothache — pain that starts without an obvious stimulus like biting or temperature
- Lingering sensitivity to heat or cold — sensitivity that persists for more than 30 seconds after the stimulus is removed, rather than resolving immediately
- Pain on biting or pressure — persistent pain when biting down on a tooth, especially if increasing over time
- Swelling around the tooth or in the face — indicating spread of infection beyond the root tip
- Discolouration of a tooth — a tooth that has become noticeably darker, often following trauma
- A pimple on the gum near a tooth — a sinus tract through which a chronic abscess is draining
- Deep decay that has reached or is close to the pulp chamber on radiographs
- A tooth that has been traumatised — particularly if the nerve has been exposed or the root fractured
Importantly, some teeth requiring root canal treatment are entirely painless — particularly when the pulp has died over time following old trauma or when a chronic abscess has been draining slowly. Radiographic detection of periapical pathology at a routine examination is a common way these cases are identified before symptoms become severe.
Endodontic treatments at Al Safwa Medical Center
Root canal treatment
Root canal treatment is the most common endodontic procedure. Under local anaesthesia, the pulp chamber and root canals are accessed through the crown of the tooth. The inflamed or infected pulp tissue is removed, the canals are cleaned and shaped using fine rotary instruments, irrigated thoroughly with antimicrobial solutions, and then filled and sealed with gutta-percha — a rubber-like material — and sealer. The access cavity is restored with a filling, and in most cases, a crown is placed subsequently to protect the treated tooth from fracture.
Modern root canal treatment at Al Safwa uses rotary nickel-titanium instruments that are significantly more flexible and precise than older stainless steel hand files, combined with electronic apex locators that measure root canal length with high accuracy. This combination reduces treatment time, improves cleaning thoroughness, and produces more predictable outcomes than older techniques. The post-treatment decision about whether a crown is required is covered in the guide to dental crown after root canal.
Apicoectomy (root end surgery)
An apicoectomy is a minor surgical procedure performed when a root canal treatment has not fully resolved infection around the root tip, or when a previous root canal cannot be retreated through the crown of the tooth due to posts, crowns, or complex anatomy. The procedure involves making a small incision in the gum, accessing the bone at the root tip, removing the very tip of the root (the apex) along with any infected tissue, and placing a small filling at the cut root end to seal it. The gum is sutured closed and healing is typically straightforward. A dedicated in-depth guide to apicoectomy in Abu Dhabi covers the procedure in full detail.
Pulpotomy
A pulpotomy is a partial pulp removal procedure — the inflamed pulp tissue in the crown of the tooth is removed while the pulp in the root canals is preserved. It is used in two main contexts: in primary (baby) teeth where complete root canal treatment is not appropriate for the developmental stage, and in permanent teeth with a specific type of pulp inflammation (reversible pulpitis in a young tooth with an incompletely formed root) where preserving pulp vitality supports continued root development. A full guide to pulpotomy in Abu Dhabi explains the procedure, who it is appropriate for, and what to expect.
The endodontic procedure: what to expect
Before treatment. A clinical examination and periapical radiograph — a detailed X-ray of the tooth and surrounding bone — is taken. In complex cases, a cone beam CT scan provides three-dimensional imaging of the root canal anatomy. The number of visits required depends on the complexity of the case and whether infection is acute or chronic.
During treatment. Local anaesthesia is administered before any instrumentation begins. A rubber dam — a thin sheet of rubber placed around the tooth — isolates it from the rest of the mouth, maintains a sterile field, and prevents irrigants from reaching the throat. The pulp tissue is removed and the canals are cleaned, shaped, and irrigated. In straightforward cases, the canals are filled and sealed in the same appointment. In cases with active infection, a medicated dressing may be placed and the tooth sealed temporarily for one to two weeks before final obturation.
After treatment. Some soreness and mild sensitivity for a few days post-treatment is normal and expected. Over-the-counter pain relief manages this comfortably for most patients. The tooth remains functional during this period. The final restoration — typically a crown — is placed after the endodontic treatment has been completed and symptoms have fully resolved.
Is root canal treatment painful?
Root canal treatment has an unfair reputation for being painful. In clinical reality, the procedure is performed under local anaesthesia and patients do not experience pain during it. The pain most strongly associated with root canal treatment is the pre-treatment pain from the infected or acutely inflamed tooth — the procedure relieves that pain. Some post-treatment soreness for two to three days is normal and resolves with standard pain relief. Published clinical research consistently shows that the majority of patients rate root canal treatment as no more uncomfortable than a routine filling procedure.
Root canal treatment vs tooth extraction: how to decide
When a tooth has irreversible pulp damage or a periapical abscess, the clinical choice is between root canal treatment (saving the tooth) and extraction (removing it). The decision involves several considerations:
Restorability. A tooth with adequate remaining crown structure that can support a post and crown is a good candidate for root canal treatment. A tooth that is so severely destroyed by decay or fracture that it cannot be adequately restored is not worth treating endodontically — extraction and replacement is the more appropriate path.
Periodontal support. A tooth with significant bone loss from advanced gum disease may not have enough support to justify the investment of root canal treatment. The prognosis of the tooth after treatment — not just the success of the root canal itself — must be assessed.
Strategic value. A tooth that supports a bridge, anchors a partial denture, or is critical to maintaining bite balance may justify more aggressive preservation efforts than one that is easily replaced.
When extraction is the right choice, the options for replacing the missing tooth — dental implants, bridges, or full restoration — should be discussed at the same time as the extraction decision.

Frequently asked questions
How do I know if I need a root canal?
The most common signs are persistent spontaneous toothache, lingering sensitivity to heat that doesn’t resolve quickly, pain on biting, swelling around a tooth, or a darkened tooth. However, some teeth requiring root canal treatment have no symptoms at all and are detected on routine radiographs. Only a clinical examination and radiograph can definitively confirm whether root canal treatment is needed.
How long does root canal treatment take?
Most root canal treatments are completed in one to two appointments of 60 to 90 minutes each. Simple single-rooted teeth can often be completed in one visit. Multi-rooted teeth (molars) or cases with active infection requiring a dressing period may need two visits. The crown placed after the root canal requires a separate appointment or two depending on the type of restoration chosen.
What happens if I don’t get a root canal?
An untreated infected tooth does not resolve on its own. The infection progresses — spreading to the surrounding bone, potentially causing an abscess, and in serious cases spreading to the jaw and surrounding soft tissues. Antibiotics treat the systemic infection temporarily but do not address the source inside the tooth. Eventually, the tooth is lost and the adjacent bone has been significantly damaged. Early endodontic treatment preserves both the tooth and the surrounding bone.
Do I need a crown after root canal treatment?
In most cases, yes. Root-canal-treated teeth have reduced moisture content and are more brittle than vital teeth. A crown protects the tooth from fracture — particularly important for back teeth that endure significant biting forces. Front teeth with adequate remaining structure occasionally do not require a crown. The detailed clinical discussion of when a crown is and is not needed is covered in the guide to dental crown after root canal.
What is an apicoectomy and when is it needed?
An apicoectomy is a minor surgical procedure that removes the tip of the tooth root along with any infected tissue when a root canal has not fully resolved infection at the root tip, or when retreatment through the crown of the tooth is not feasible. It is not a replacement for root canal treatment — it is used in specific situations where the root canal has been completed but a persistent periapical lesion remains. A full explanation is in the dedicated apicoectomy guide.
