Root Canal Treatment in Dublin

Inside each tooth is the pulp, a soft tissue containing nerves and blood vessels. Deep decay, a crack, repeated dental work or trauma can inflame or infect it. Irreversible pulpitis may cause prolonged sensitivity to hot or cold, spontaneous pain or pain that disturbs sleep. If bacteria spread beyond the pulp, an abscess may develop around the root tip, sometimes causing tenderness when biting, swelling, a bad taste or a spot on the gum.

Symptoms do not always reflect the extent of disease. A badly damaged pulp can die and the tooth may briefly become less painful even though infection remains. Assessment normally includes the history of the pain, examination, tests on the tooth and a dental X-ray. A CBCT 3D scan may be advised when ordinary images do not provide enough detail, particularly for unusual canal anatomy, resorption, previous treatment or root-end surgery.

The purpose of root canal treatment is to remove diseased tissue and bacteria, disinfect and seal the internal space, and retain a tooth that can be predictably restored. Extraction may be more appropriate if the tooth is split, has too little sound structure, has severe supporting bone loss or resorption, or cannot be restored. Facial swelling that is spreading, fever, difficulty swallowing or breathing, swelling near the eye, or feeling acutely unwell requires urgent dental or medical attention.

The tooth is numbed with local anaesthetic, so the procedure should not be painful, although pressure and vibration can be felt. A protective rubber sheet is usually placed around the tooth to keep it dry and reduce contamination. The dentist makes an opening into the tooth, locates the canals, removes inflamed or infected tissue, and shapes and disinfects the spaces with fine instruments and cleaning solutions.

Modern endodontic care may combine microscope or loupe magnification with advanced irrigation and adjunctive disinfection technologies, including laser-assisted disinfection or ozone therapy where clinically appropriate. Better illumination and magnification help reveal fine anatomy, while the disinfection stage aims to reduce bacteria throughout the canal system before it is sealed.

The canals are then filled and sealed to reduce the chance of bacteria returning, and the opening is closed with a temporary or permanent restoration. Completing treatment in one session can reduce the opportunity for recontamination between appointments, improve convenience and restore function sooner. Long-term outcomes are comparable with multi-visit treatment in many cases, although infected, anatomically complex or previously treated teeth may still need more than one visit. The published incisor / frontal price notes that 95% are completed in one session at the €600 microscope-assisted fee, but the number of appointments for an individual tooth depends on the clinical findings.

When the numbness wears off, the tooth and surrounding tissues may feel tender for several days, especially if there was inflammation before treatment. Follow the dentist's advice on pain relief, avoid chewing hard foods on a temporarily restored tooth and return for the final restoration. Contact the clinic if pain or swelling is increasing rather than settling, the temporary filling comes out, your bite feels markedly high, or your previous symptoms return.

Root canals can be very narrow, curved or hidden by calcification. Magnification and focused illumination from a dental microscope improve the view into the tooth and can help the dentist locate canal openings, inspect fine detail and manage complex anatomy. A microscope does not guarantee success, and the outlook still depends on factors such as the tooth's condition, anatomy, infection, restorability and the quality of the final seal.

Incisor / frontal root canal treatment costs €390 – €600, with microscope-assisted treatment at €600 and 95% completed in one session. Premolar treatment costs €490 – €700, with microscope-assisted treatment at €700. Molar treatment costs €550 – €800, with microscope-assisted treatment at €800. A periapical X-ray costs €30 and a CBCT 3D scan costs €150 when required.

The first dental consultation is free, and an examination under PRSI is free for eligible patients. If needed after root canal treatment, a post core costs €300 – €400 and internal bleaching of a darkened root-treated tooth costs €250. Suitability and the full treatment plan are confirmed after examination; the price of any service not listed here is confirmed at the consultation.

When infection or pulp death extends beyond the root tip, it can cause inflammation, widening of the periodontal ligament space and local periapical bone loss. In some cases, this inflammation can also contribute to tooth mobility. By removing the source of infection, successful root canal treatment can allow the inflammation to resolve, the surrounding bone to regenerate gradually and infection-related mobility to improve as the tissues heal.

Root canal treatment does not mechanically strengthen a tooth, and improved stability depends on the remaining periodontal support. Mobility caused by advanced gum disease may require additional periodontal treatment and may not resolve through root canal treatment alone. Healing is monitored over time with follow-up images because improvement around the root can continue after symptoms have settled.

A tooth can remain painful or develop infection months or years after a previous root canal if anatomy was missed, the seal has broken down, a restoration leaks, or a new crack or decay allows bacteria back in. Retreatment involves reopening the tooth, removing the previous root filling where possible, cleaning the canal system again and resealing it. Retreatment costs €100 in addition to the applicable root canal fee, and the dentist will first assess whether the tooth is restorable and whether retreatment offers a reasonable prospect of retaining it.

If infection persists at the root tip and conventional retreatment is unsuitable or has not resolved it, an apicectomy may be considered. Under local anaesthetic, the gum is opened, inflamed tissue and a small part of the root tip are removed, and the end of the canal is sealed where appropriate. Apicectomy / root end surgery costs €600. Discomfort, swelling and bruising can follow, while possible risks include bleeding, infection, gum recession and injury to nearby structures; the specific risks vary with the tooth's position.

Root resorption is the loss of hard tooth structure through biological activity. Internal resorption begins within the pulp space, while external resorption starts on the outside surface of the root. It may be associated with trauma, inflammation, infection, orthodontic movement or other causes, and can progress without obvious symptoms. Dental X-rays help identify and monitor it; CBCT can show its position and extent in three dimensions when that additional information is clinically justified.

Treatment depends on whether resorption is internal or external, where it lies, whether it communicates with the mouth or root canal, and how much sound tooth and supporting bone remain. Root canal treatment may stop some forms of inflammatory resorption by removing infected pulp tissue, while other cases may need repair, surgery, monitoring or referral. Severely resorbed teeth sometimes cannot be saved, and extraction may be the safer or more predictable option.

A root-treated tooth still needs protection from leakage and fracture. A durable filling is required, and a crown is often recommended afterwards, particularly for a premolar or molar that has lost substantial tooth structure. A crown does not strengthen the root or remove every fracture risk, but it helps protect the remaining tooth during chewing. Until the definitive restoration is fitted, avoid biting hard foods on that tooth and attend the recommended reviews.
