Root canal treatments are one of the most dreaded of dental procedures. If the dental decay is left untreated, it progresses deep inside the tooth and reaches the pulp tissue. Root canal treatment is done to replace the infected pulp with a filling.
The treatment is used to save the teeth which would otherwise need to be removed. Let us understand the procedure in detail. Click here to get more information regarding root canal treatment.
How does a tooth get infected?
The root canals of teeth consist of nerves and blood vessels, which nourish the teeth providing oxygen and nutrients. When the dental decay in the outer layers of the teeth is neglected, it progresses to the root canals, where the nerves and blood vessels get infected and inflamed. The inflamed pulp tissue dies and is replaced by infected material and pus.
This causes pain and swelling, and if left untreated may cause damage to the surrounding bone structure resulting in a tooth abscess. Hence root canal treatment is done to remove the infected pulp and replace it with a filling.
Once the infected pulp is removed, the nutrition for the tooth comes from the tissues surrounding the tooth. Other reasons that may damage the teeth and cause infection are accidental cracks, leakage from the fillings and infection from the gums reaching to the base of the roots.
