What are Endodontics?

Also known as 'root canal treatment' or devitalisation, it is a specialty of dentistry that deals with diseases of the inside of the tooth, such as the nerve and root. The purpose of this treatment is to eliminate the pain caused by inflammation inside teeth to save the tooth and prevent its extraction.

Causes Associated with Endodontics

The most common causes that require endodontic treatment of a tooth are trauma, fractures and deep cavities. This is why delaying a check-up may increase the risk of dental inflammation.

When Is Endodontic Treatment Necessary?

Patients are required to undergo Endodontic treatment when the tooth is already so damaged due to cavities, fractures or wear and tear that the nerve structure tissue is already compromised.

Symptoms Linked To Dental Inflammation

Difficulty chewing

Jaw pain

Nerve Exposure



If you have these symptoms frequently, you should consult your dentist to determine their cause.

Consequences of Leaving Untreated

Endodontic treatment aims primarily to prevent infections that can be very dangerous to oral health. However, if you do not see your dentist in time to resolve your dental problem, you may suffer from severe pain and may not be able to avoid having teeth removed. Endodontic treatment is necessary to prevent tooth extraction and to prevent infections that are potentially dangerous.

How Does The Treatment Work?

The treatment consists in removing the part of the tooth that is infected and replacing or filling the space. This procedure is performed under the effect of local anaesthesia, so the patient does not feel any pain or discomfort.

Tissue Removal

The dentist removes the infected tissue from the inside (the canal) of the tooth.

Step by step



After, the root canals are cleaned and widened so that they can be filled in.

Step by step
