What is a root canal treatment?

Severe tooth decay can reach the nerves inside the tooth, which can lead to the inflammation of the pulp. The circulation of the tooth stops, and bacteria start to spread in the gum and the jawbone surrounding the teeth and cause an abscess.

Root canal treatment can be used in case of severe tooth decay, in order to save a tooth with infected pulp. This can be caused by inflammation of the tooth or physical trauma. The pulp is the soft tissue at the center of the tooth that contains the nerves and is surrounded by dentine.

Dentine is the hard tissue of the tooth. It surrounds the pulp and from the outside it is covered by enamel on the crown and cementum on the root.

First, a small opening is made on the crown to remove the infected pulp. Since this is done under local anesthesia, the treatment is completely painless. After cleaning the root canal the dentist enlarges it with special files, so it can be easily filled.

In case the root canal treatment is carried out over multiple sessions, the dentist may place medication in the cleaned canal to kill any remaining bacteria and seals the tooth with a temporary filling.

During the following visit, the medication and the temporary filling is removed, and the root canal filling is placed. Finally, the dentist seals the tooth with a filling or a crown, depending on the extent of the damage.

Devitalized tooth can decay too, therefore practicing good oral hygiene is very important. Brushing your teeth regularly, with a good technique as well as using mouthwash and flossing can go a long way in preserving your oral health. Dental check-ups are recommended at least twice a year, to avoid problems going unnoticed.
