Root canal treatments are one of the most dreaded of dental procedures. Dental decay will progress deep inside the tooth and will reach the pulp tissue if you leave it untreated. With the help of root canal treatment for example with a filling, it is possible to replace the infected pulp.
How does a tooth get infected?
The root canal of teeth includes nerves and blood vessels, which nourishes the teeth by providing nutrients and oxygen. In the outer layers of the teeth when the dental decay is neglected, it progresses to the root canals, where the blood vessels and nerves get inflamed and infected. The inflamed pulp tissue dies and by infected material and pus, it is replaced.
This causes swelling and pain, and it may cause damage to the surrounding bone structure resulting in tooth abscess if you leave it untreated. Hence the treatment of root canal is done to remove the infected pulp and to replace it with a filling.
Root canal procedure:
It is also known as endodontic treatment; cleaning and sterilizing the root canal and removing the infected tissue is involved under the root canal treatment. Depending on the situation this procedure is carried out by your dentist over two or more visits. If the tooth has an active infection, to reduce the pain and infection antibiotics are prescribed for 3-5 days.
Prior to treatment local anaesthesia is given so that the patient is comfortable. First of all, during the treatment, a rubber dam is placed around the infected tooth to ensure the tooth is dry and to prevent contamination of the canals
