Endodontics – root canal treatment

Dental Practice at 40 Harley Street

Tooth loss can have an adverse effect on a person’s quality of life. It can make it difficult to chew food properly and also impacts on their confidence and self-esteem. Many teeth can be saved and returned to normal function with a procedure called endodontic treatment or root canal therapy.

Inside the tooth there is a soft tissue, called the dental pulp, which contains blood vessels, nerves and connective tissues. This pulp is connected to the tissues surrounding the root. Endodontics treats disease and problems related to this pulp tissue such as abscesses and acute pain. There are various causes of these symptoms including deep decay, faulty fillings or crowns, cracks in the tooth or dental trauma. Benefits of treatment include:

  • Helping to preserve teeth which may otherwise be lost.
  • Treatment seals the tooth to prevent re-infection.
  • Pain-free procedure carried out by our experienced endodontist, Dr Vittorio Franco.

Endodontic treatment consists of cleaning the root canal and then filling the inside of the tooth with biocompatible material to seal the root. Occasionally, secondary treatment is necessary. You can read more about this in the frequently asked questions below.

Frequently asked questions

About root canal treatment (endodontics) at 40 Harley Street

  1. Who can perform endodontic treatments?

    Every dentist can perform endodontic procedures, but often they refer patients needing endodontic treatment to a specialist endodontist. An endodontist is particularly skilled at performing root canal treatment, re-treatment and endodontic microsurgery. Specialists usually use an operative microscope to carry out a range of procedures from simple cases to very complex procedures efficiently, painlessly and usually in a single visit.

    Dr Vittorio Franco is our highly-experienced endodontist at 40 Harley Street, London.

  2. When and why is it sometimes necessary to have secondary treatment (re-treatment or endodontic microsurgery)?

    Sometimes re-treatment of a previously endodontically treated tooth is necessary. This happens when bacteria are present inside the tooth and affect surrounding root tissues. These bacteria could have survived the first treatment or penetrated afterwards through new decay or a loose, cracked or broken crown or filling.

  3. What happens during root canal treatment?

    The inside of the tooth is cleaned both mechanically and chemically. It is then filled with biocompatible material to seal the root.

  4. What happens after root canal treatment?

    After the endodontic treatment, a temporary filling will be placed into the access cavity. The treated tooth could be moderately sensitive for a few days when chewing, but this usually resolves quite quickly. Very occasionally a course of antibiotics might be required. Endodontic treatment is only the first step in returning your tooth to its full function.

    If you have been referred by another practice, the tooth needs to be treated by your own dentist as soon as possible after endodontic treatment in order to restore its function and protect it from bacterial re-contamination. Our endodontist will communicate with your dentist about your case and the recommended final restoration.

    In cases where there was infection, follow up x-rays will be needed until healing is complete. Teeth that have undergone endodontic treatment and have been properly restored should in the majority of cases last as long as your natural teeth.

  5. How can I prevent further problems?

    After root canal treatment, it’s even more important to maintain excellent oral hygiene with regular and thorough brushing and flossing. It is also essential to attend all recommended dental health checks and hygiene therapy appointments.
