Root canal treatment in Barcelona

Root canal treatment aims to preserve a tooth that might otherwise need to be removed. At CHC Clínica Dental, we use local anaesthetic, specialised instruments and a conservative approach: we try to preserve the natural tooth whenever it is viable.

What is root canal treatment and what does it do?

Root canal treatment, also called endodontic treatment, removes inflamed or infected pulp from inside the tooth. The canals are cleaned, disinfected and sealed to reduce the risk of reinfection. The final restoration and follow-up also affect the outlook for the tooth.

The aim is to keep your natural tooth and restore its chewing function. Although the pulp is removed, the tissues around the root remain sensitive, so some discomfort can occur afterwards.

If the tooth cannot be saved, we assess extraction and whether replacement is appropriate. Options may include an implant, a bridge or a removable denture, depending on the case. An implant is not an inevitable consequence of every extraction.

When might it be needed?

Root canal treatment may be indicated when the dental pulp—the tissue inside the tooth containing nerves and blood vessels—is irreversibly inflamed or infected. Common causes include:

  • Deep decay reaching the pulp.
  • Dental trauma.
  • A fracture exposing the inside of the tooth.
  • Chronic infection, with or without visible swelling.

Not every toothache needs root canal treatment. Infection can also be present without symptoms. A clinical examination and X-rays help establish the diagnosis.

Root canal treatment, step by step

1. Diagnosis and X-ray

We examine the tooth and take a periapical X-ray to assess the canals, root length and signs of infection. This guides the plan and the number of appointments, which may change with progress.

2. Local anaesthetic

This is given before treatment. Inflammation can make effective anaesthesia more difficult in some cases. We check that it is working and adjust it if you feel pain.

3. Isolation

A rubber dam is placed around the tooth to separate it from the rest of the mouth, keep the working area clean, limit bacterial contamination and protect you during the procedure.

4. Access and canal cleaning

A small opening is made in the crown to reach the canals. Endodontic files remove the affected tissue and clean the canals towards the root tip.

5. Disinfection

Disinfectant solutions are used to reach bacteria that the instruments cannot. This is an essential part of treatment.

6. Filling the canals

Once cleaned and disinfected, the canals are filled with a biocompatible material called gutta-percha. Sealing, restoration and check-ups reduce the risk of reinfection but do not eliminate it completely.

7. Final restoration

The tooth needs a restoration. A filling may be sufficient, or a ceramic or zirconia crown may be needed to protect a structure weakened by decay, fractures or canal access. This is assessed individually.

How long can a root-treated tooth last?

The aim is to preserve it for many years, but no fixed lifespan can be guaranteed. The remaining healthy tooth structure, root condition, canal cleaning and sealing, restoration, oral hygiene and follow-up all matter. Inadequate protection when the tooth needs coverage can increase the risk of fracture.

Frequently asked questions

Is root canal treatment the same as removing the nerve?

That is a common way of describing it. The pulp, containing nerves and blood vessels, is removed while the tooth structure is retained. The tissues around the root remain sensitive.

Can I eat afterwards?

Wait until the anaesthetic has worn off to avoid biting yourself accidentally. Chewing on the other side may help during the first few days. Follow the advice for your temporary and final restoration.

Will I need antibiotics?

Not routinely. Your dentist considers them in selected circumstances based on the extent of infection, systemic signs and individual risk factors. They do not replace dental treatment.

What happens if I do not have the recommended treatment?

An infection can progress, form an abscess, affect surrounding bone and eventually require tooth removal. Severe cases can cause systemic complications, particularly in people with a weakened immune system.

Can root canal treatment fail?

Yes. Infection can persist or return, for example where the canal anatomy is complex. Retreatment or root-end surgery may be considered, depending on the diagnosis.

Can the tooth become darker?

This can happen over time. For a visible tooth, options such as internal bleaching or a veneer may be assessed during a review.
