What is root canal work?

Updated May 12, 2026

Root canal work is a treatment for severely infected or decayed teeth where the cause originates in the nerve of the tooth. The treatment consists of repairing and saving the teeth by removing the dental pulp, before cleaning and sealing the inside of the tooth. The dental pulp is the soft tissue inside the tooth, made up of nerves and blood vessels.

Carrying out root canal work helps to repair and address the damage in infected and abscessed teeth. The causes can include decay, cracks or fractures, or repetitive dental procedures. Some common symptoms are: pain, prolonged sensitivity to heat or cold, sensitivity when chewing, swelling of the gums and discolouration. In some cases the patient may present no symptoms.

Step by step

Root canal work treatment phases

Root canal work consists of five phases that begin with an x-ray and diagnosis of the patient's condition, and end once the tooth has been restored.

X-ray and diagnosis

The first step is to take an x-ray that will help assess the possible involvement of the pulp or nerve of the tooth. This x-ray allows the dentist to make a diagnosis and decide which treatment is appropriate.

Local anaesthetic

The process begins with the application of local anaesthetic to numb the area. Additionally, a rubber dam is placed around the tooth to prevent saliva or blood from entering while the root canal is being carried out.

Pulp extraction

To access the nerve and pulp chamber, the tooth is drilled. The pulp, bacteria and decomposed nerve tissue are removed. Then the sides of the root canals are scraped and filed. The remnants are eliminated with chlorhexidine or sodium hypochlorite.

Root sealing

With the tooth completely clean and disinfected, the canals are sealed. A special sealing paste and gutta-percha, a rubber compound, are placed in the root canal of the tooth.

Restoration of the tooth

Usually, teeth that need root canal treatment also have a fracture or extensive decay. It is often necessary to place a crown, an internal reinforcement (post) or another restoration to fully protect and restore the tooth, both functionally and aesthetically.

Jasmin

Una clínica excelente y muy recomendable. Acaban de hacerme un tratamiento de endodoncia complicado, el endodoncista tiene mano de santo, estuvo trabajando durante una hora y media. Tenía una inflamación importante y me cuidaron durante las semanas previas con mucha paciencia. Tengo insuficiencia cardiaca y se lo tomaron muy en serio. Estoy agradecida a todo el personal de la clínica.

Nadia

He estado haciéndome una endodoncia (aclaro que me da pánico ir al dentista). Puedo asegurar que es la primera vez que no me ha dolido, no he tenido agobio de tragar saliva acumulada, ni nada de nada. Se han portado súper bien conmigo.

Sergio

Me hicieron una endodoncia y la experiencia ha sido muy positiva. Ningún dolor durante el procedimiento y el personal muy simpático.

FAQs about root canal work

Root canal work is a dental procedure that treats the inside of the tooth when the pulp is infected or damaged. It is necessary to save a tooth that would otherwise need to be extracted, eliminating pain and preventing the spread of infection.

Symptoms that may indicate the need for root canal work include intense tooth pain, prolonged sensitivity to heat or cold, swelling and redness in nearby gums. However, in some cases there are no visible symptoms, so an assessment by a dentist is essential.

Root canal work is generally carried out under local anaesthetic. The dentist accesses the tooth pulp, removes the damaged or infected tissue, cleans and disinfects the space, and then fills and seals it. A crown is often placed to strengthen the tooth.

Although it has a reputation for being painful, most patients find the procedure is not very uncomfortable. Local anaesthetic minimises pain during treatment, and any subsequent discomfort can generally be managed with pain medication.

Cost varies depending on the case and type of root canal work. You can consult the Adeslas price list in the prices section of this page.
