The root is cleaned and disinfected and then filled with gutta percha to prevent any further infection occurring. All root canal procedures are carried out using single use instruments, the most up to date technology and the latest materials. Root treatments on back teeth can be more complicated because they have a more nerve canals, typically up to three or four.
Once filled it is usually advised that the back teeth are crowned to prevent tooth fracture in the future. Root filled teeth are more prone to fracture than teeth with intact nerves. Occasionally there is often post-operative discomfort which is short-lived and usually contained with analgesics.
