Root Canal Treatment (Endodontics) in Dubai

The common signals are pain to hot or cold that lingers for minutes after the stimulus is removed, pain that wakes you at night, throbbing that is worse lying down, pain on biting a single tooth, tenderness of the gum over a root, a swelling or a small recurring pimple on the gum, and a front tooth that has darkened.

Some teeth needing treatment have no symptoms at all. A nerve can die quietly after a knock years earlier or under a large old restoration, and the first sign is an area of bone loss at the root tip found on a routine radiograph.

The reverse is also true: not every painful tooth needs a root canal. Sensitivity that stops the moment the cold is removed, pain from a cracked restoration and pain referred from the sinus are all treated differently, which is why diagnosis precedes treatment rather than accompanying it.

The diagnosis rests on tests rather than on the location of the pain, which patients frequently misplace by several teeth and occasionally between arches. The dentist tests the response of the suspect tooth and its neighbours to cold, checks tenderness to percussion and to pressure on the surrounding bone, examines for cracks and for a sinus tract on the gum, and takes a periapical radiograph.

Where the anatomy is not readable in two dimensions the clinic takes a cone beam CT scan on site. Three-dimensional imaging changes the answer in specific situations: an extra canal in a molar that a plain film superimposes, a root fracture, an unusually curved root, a lesion at the root tip that has not yet reached the bone surface, and re-treatment of a tooth where the previous work has to be assessed. Details are on the page about CBCT and dental X-ray.

The tooth is anaesthetised and isolated with a rubber dam, which keeps saliva and its bacteria out of the canal system and stops instruments and irrigants entering the mouth. Treatment without isolation is treatment carried out in a contaminated field.

An access cavity is made, the canals are located and their length measured, and the canal system is shaped with fine instruments while being irrigated. The irrigation does much of the disinfection, reaching the branches and irregularities that no instrument touches. The canals are then dried and filled with a sealing material, and the access cavity is closed.

Where infection is extensive, a medicament may be placed and the tooth sealed temporarily for a period before the filling is completed. Between appointments the temporary seal is what protects the work; if it comes out, the tooth needs to be seen rather than left.

Root canal treatment is not finished when the canals are sealed. The tooth has lost structure to the decay or fracture that started the problem and to the access cavity, and a back tooth in that condition is at real risk of splitting under load. A vertical fracture running below the gum is usually the end of that tooth.

For that reason a molar or premolar is normally restored with a cusp-covering restoration — an onlay or a crown — rather than a plain filling, and the sooner after treatment the better. Front teeth with limited loss can often be restored directly.

The definitive restoration also matters biologically: a temporary seal left in place for months leaks, bacteria re-enter the canal system, and a technically good root treatment fails for reasons that have nothing to do with the root treatment.

Expect the tooth to be tender to bite on for a few days, sometimes up to a week, as the tissue around the root settles. Ordinary painkillers cover it. Chew on the other side until the definitive restoration is placed, particularly if a temporary filling is in place.

What is not expected: pain that increases after the third day, swelling of the face or gum, fever, or the temporary filling coming out. Those need to be reported rather than waited out, and are handled through emergency dental care.

Treated teeth are reviewed radiographically after six to twelve months to confirm that bone at the root tip is healing. That review is how a problem is found while re-treatment is still straightforward.

Root canal treatment is carried out under a dental operating microscope. The working field is a chamber a few millimetres across containing canal openings that can be narrower than a human hair, and the difference between magnified, coaxially illuminated vision and working by feel is not cosmetic.

What magnification changes in practice: canal openings that are calcified or hidden under a shelf of dentine are found rather than missed — the second mesiobuccal canal of an upper first molar is present in most of those teeth and is the classic reason a treated molar keeps hurting; cracks running across the pulp floor become visible, and a cracked root changes the plan from treatment to extraction; a fractured instrument left by previous treatment can be seen and, in many cases, retrieved; and access can be kept conservative, because the operator can see where to stop cutting instead of removing dentine to gain a view.

Magnification does not replace three-dimensional imaging — the two answer different questions, and both are used. What it replaces is guesswork inside the tooth. More on the imaging side is on the page about CBCT and dental X-ray.

Root canal treatment at ELEMENTAL starts from AED 2,500 for a single canal. A two-canal tooth is AED 3,500, three canals AED 4,000 and four canals AED 4,500. A consultation with the endodontist is AED 650, and full-mouth CBCT imaging, when it is needed to plan the treatment, is AED 1,000. The number of canals is confirmed on the scan before treatment starts. Prices are current as of August 2026.
