Endodoncia

Endodontics is the dental specialty focused on the inner structure of the tooth. At the centre of every tooth is the dental pulp, soft tissue containing nerves, blood vessels, and connective tissue. When this pulp becomes infected or irreversibly damaged, it cannot heal on its own. Endodontic treatment removes the source of infection, clears the tooth's canal system, and seals it against reinfection, preserving a tooth that would otherwise need to be extracted.

The most common endodontic procedure is root canal treatment. But the specialty also covers retreatment of previously treated teeth that have failed or become reinfected, surgical procedures at the root tip, and the management of dental trauma affecting the pulp.

¿Qué Es la Endodoncia?

Each tooth has a hollow space inside called the pulp chamber, which extends down into the roots through narrow channels called root canals. The pulp inside contains the nerves and blood supply that the tooth needed during development. Once a tooth is fully formed, it can survive without its pulp, but the pulp's nerves still respond to temperature, pressure, and bacterial invasion.

When bacteria reach the pulp, either through deep decay, a crack, or trauma, the pulp becomes inflamed and eventually infected. This infection cannot clear itself, and without treatment it spreads: first through the root tip into the surrounding bone, then potentially to adjacent structures. Endodontic treatment interrupts this process by removing the infected tissue, eliminating the bacteria from the canal system, and sealing the tooth against re-entry.

Why Preserving the Natural Tooth Matters

No dental restoration fully replicates the function of a natural tooth. Natural teeth transmit chewing forces into the jawbone, maintaining bone density in a way that implants approximate but do not fully match. They are anchored by the periodontal ligament, a complex shock-absorbing structure that no artificial restoration includes. And they do not require the healing period that implant placement involves.

Extraction creates a gap that requires a replacement, whether an implant, bridge, or denture, each of which involves additional cost, time, and its own maintenance requirements. When a tooth can be saved through endodontic treatment and properly restored, it is almost always the better long-term outcome. A successfully treated and crowned tooth can last for decades.

¿Cuándo Se Necesita Tratamiento Endodóntico?

Endodontic treatment is needed when the pulp has become infected, irreversibly inflamed, or has died. The most important thing to understand is that the early and middle stages of this process are often painless. A tooth can have a dying or dead pulp with no significant symptoms until an abscess forms. Professional assessment is more reliable than waiting for pain to indicate a problem.

Symptoms that suggest pulp involvement

• Persistent or spontaneous tooth pain, particularly throbbing or waking at night
• Sensitivity to heat or cold that lingers for more than a few seconds after the stimulus is removed
• Pain when biting or chewing on a specific tooth
• Tooth darkening or discolouration, suggesting the pulp tissue has died
• Swelling of the gum near a tooth, or a visible bump resembling a pimple on the gum
• A tooth that has been cracked, fractured, or subjected to trauma, even without obvious symptoms

Common causes of pulp damage

Deep decay that has reached the pulp chamber allows bacteria direct access to the nerve tissue. A crack or fracture in the tooth provides a pathway for bacteria to enter even when the outer surface looks intact. Physical trauma, a blow to the mouth or a fall, can disrupt the blood supply to the pulp without any visible fracture. Teeth that have had repeated dental procedures over the years can develop pulp inflammation from the cumulative stress. And in some cases, severe gum disease can affect the root and surrounding bone in a way that involves the pulp tissue.

Procedures in Endodontics

Tratamiento de conducto (Endodoncia)

Root canal treatment removes the infected or inflamed pulp from inside the tooth, cleans and disinfects the entire root canal system, and seals it with a biocompatible material called gutta-percha. The procedure is performed under local anaesthesia. Most straightforward cases are completed in a single appointment of 60 to 90 minutes. Back teeth with multiple canals, or teeth with complex anatomy, may require two appointments. A permanent restoration, typically a crown for back teeth, is placed after treatment is confirmed to be healing well.

Root canal retreatment

When a tooth that has previously had root canal treatment does not heal as expected, or when a new infection develops years later, retreatment is often possible. The existing filling material is removed from the canals, the canals are re-examined and re-cleaned, any new areas of infection are addressed, and the tooth is resealed. Retreatment is more complex than initial root canal treatment, but it offers the opportunity to keep a tooth that might otherwise need to be extracted. CBCT imaging is used before retreatment to map the canal anatomy and assess the extent of any periapical changes.

Apicoectomy (root-end surgery)

In cases where root canal treatment or retreatment cannot fully resolve an infection at the root tip, an apicoectomy provides a surgical alternative to extraction. The tip of the root is accessed through a small incision in the gum, the infected tissue at the root apex is removed, the root end is resected and cleaned, and the root tip is sealed from the surgical side. Apicoectomy is performed under local anaesthesia and is typically reserved for cases where the canal cannot be adequately accessed from the crown of the tooth.

Vital pulp therapy

When decay has reached the pulp but the pulp is still partially vital and has not progressed to full infection, vital pulp therapy aims to preserve the living pulp tissue. Pulp capping involves placing a biocompatible material directly over an exposed pulp to encourage healing and the formation of a natural barrier. Partial pulpotomy removes only the most superficially affected pulp tissue. These procedures are more commonly used in children and young adults where the tooth's root has not yet fully formed, but can also be appropriate in certain adult cases where the pulp exposure is small and the surrounding tissue is healthy.

What to Expect Before, During, and After Treatment

Antes del tratamiento

The initial appointment involves a clinical examination and diagnostic X-rays to assess the extent of infection, the root canal anatomy, and the condition of the surrounding bone. For complex cases, a CBCT (3D cone beam CT) scan may be taken to provide a three-dimensional view of the root system. If an acute abscess is present, antibiotics may be prescribed before treatment begins to reduce the acute inflammation, though antibiotics alone cannot resolve a pulp infection.

During treatment

Local anaesthesia is administered and the area is confirmed to be fully numb before treatment begins. A rubber dam is placed around the tooth to keep the working area clean and prevent saliva from contaminating the canals. The procedure involves no sharp pain for the vast majority of patients. If you feel more than pressure or mild discomfort at any point, tell your dentist immediately. Additional anaesthesia can be given.

Después del tratamiento

Some soreness around the treated tooth in the first 48 to 72 hours is normal and expected. It is the tissue's response to the procedure, not ongoing infection, and typically resolves without prescription medication. Avoid chewing on the treated side until the permanent restoration is placed. A tooth with only a temporary filling is vulnerable and should not be used for hard foods. Contact your dentist if you experience severe or increasing pain, significant swelling, or the temporary filling coming out.

Endodontic Treatment for International Patients

Straightforward root canal treatment can be completed in a single appointment of one to two hours, making it manageable within a short Istanbul visit. Complex cases, retreatment, and apicectomy may require two appointments over two to three days. For patients combining endodontic work with crown placement or other restorative treatment, the timeline is planned around the full treatment sequence.

Resumen

Endodontics preserves teeth that would otherwise need to be extracted. Root canal treatment, retreatment, apicoectomy, and vital pulp therapy each address different stages and presentations of pulp disease, all with the goal of keeping the natural tooth in place and functional.

The most important misconception to address is that root canal treatment is painful. It is not. The infection that makes treatment necessary is painful; the treatment removes it. Delaying because of fear of the procedure typically means the infection worsens, the treatment becomes more complex, and the risk of losing the tooth increases.

The most important clinical fact to remember is that the crown placed after root canal treatment is not a separate cosmetic addition. It is the primary factor determining whether the tooth survives long-term. A root canal without a crown on a back tooth is a tooth waiting to fracture.
