The root canal is the central cavity that every tooth houses. It contains dental pulp that comprises blood vessels and nerves that are responsible for the nourishment and sensation of the tooth. Sometimes, the root canal can get severely infected when a cavity grows deeper and reaches the inner layers of the tooth. This leads to a condition called root canal infection, which can put the tooth at risk of being extracted.

What causes a root canal infection?

The plaque and tartar that accumulate on the surface of the teeth are known to be the primary cause of a root canal infection. The microbes in the tartar deposits release harmful acids when they feed on the food debris in the mouth. This can erode the enamel and cause harm to the inner layers of the teeth. When the microbes gain access to the root canal cavity, they can cause serious infection.
External trauma to the teeth can damage them and cause chipping, cracks, or even tooth fracture. This exposes the root canal to the microbes in the mouth and potentially leads to severe infection when left untreated.
Gum diseases are also known to cause a root canal infection. The microbes in the infected gum tissues can progress on to the teeth and the jawbone as well.

What are the symptoms of root canal infection?

  • Severe pain in the teeth and gums whenever you bite or chew food
  • Persistent irritation in the gum tissues
  • Bleeding and release of pus near the infected tooth
  • The decay of nearby gum tissues
  • Loosening of the tooth from its socket
  • Jawbone deterioration
  • The infected tooth would experience elevated levels of sensitivity
  • Discoloration of the infected tooth

How is root canal therapy performed?

A root canal therapy is widely known as the last resort method of saving a severely infected tooth. The dentist will thoroughly screen your teeth to determine the extent of infection. After this, the teeth will be cleaned to prevent the microbes from entering the infected region. The dentist will create a tiny hole on the infected tooth to extract the decayed pulp from within.
With the help of dental files, the infected pulp is removed. The dentist will then scrub the walls of the cavity to get rid of the microbes. A jet of water will rinse away the debris. Before the hole is sealed off with a filling, a small amount of medication will be placed inside the tooth to prevent reinfection.
