root canal issues

Root canal therapy aims to remove bacteria from the infected root canal, avoid reinfection, and save the original tooth.

Common causes of root Canal issues are leftover infections or bacteria entering the tooth’s pulp.

what causes root canal

Causes of root canal infections are uncommon, but a tooth can get infected even after a root canal has been performed. A root canal is a procedure done to save a tooth that has been extensively decaying or infected. A root canal infection, like any other infection, a root canal infection can spread to surrounding tissue in the mouth, including additional teeth, gums, and cheek and facial tissue.

The infection will not go away until you treat it, and the longer you wait, the worse it will become. The extent to which the illness spreads is determined by how quickly you seek treatment after experiencing symptoms. If you seek treatment within hours or days of the illness beginning, the infection’s spread to the tooth and neighboring teeth and tissues can be limited.

An untreated root canal infection can extend far beyond the tooth. The infection can spread to the jaw, cheek, and even the circulation in some cases.

A tooth might become infected for various reasons, even after a root canal treatment. The common causes of root canal issues are:

  • The form of your root canals can be complex, and infection regions may go undetected during the initial operation.
  • Your tooth may have narrow or curved canals that were not thoroughly cleaned and disinfected during the root canal procedure.
  • Your tooth could potentially have extra canals home to bacteria that can reinfect a tooth.
  • If the crown or permanent repair is not placed immediately after treatment, dangerous bacteria may re-infect your tooth.
  • After treatment, your tooth may develop a new cavity or become cracked or damaged, resulting in a new root canal infection.
