Root canal therapy is required when an infected tooth needs treatment to restore its original health and strength. An infected, decayed, traumatized tooth and gum diseases influence the condition of the teeth, leaving them accessible to attack from germs and bacteria. This bacteria can damage the roots of the teeth, and if left untreated, will eventually damage the tooth’s pulp (the soft tissue inside the tooth made up of blood vessels, nerves and lymph vessels). Root canal treatments becomes a necessity when the pulp of the tooth is infected.
An infected pulp causes pain and infection but there may be various symptoms that may indicate a need for root canal therapy. These symptoms can include but are not limited to intense sensitivity to hot and cold temperatures, swelling of gums, darkening colour of the tooth or severe and painful headaches.
Root canal therapy involves the removal of the infected pulp and placement of a restoration to fill the void, thus helping to protect from further infections. If the infected pulp remains untreated the bacteria will gradually spread to the adjoining gums, bone and teeth complicating and worsening the condition of your oral health.
