what is root canal treatment? 

 

Teeth are held in the jaws by their roots. Front teeth normally have one root, but teeth further back in the mouth can have more.

 

At the core of each tooth is a soft mass of tissue called the pulp. In a healthy tooth the pulp contains living fibres, cells, nerves and a blood supply, extending into the root through the root canal.Decay or injury can destroy the living pulp. Because dead pulps lack a blood supply, it is more prone to infection leading to an abcess and pain. Root canal treatment involves removing the damaged or dead pulp and filling the space left in the canal. The remaining tooth can then be repaired. 

 

how long will it take?

 

Depending on the complexity of the root canals it can range from one visit to multiple visits. 

 

is it painful?

 

You will be numb during the procedure therefore usually nothing will be felt. However it is common to experience discomfort for a few days post operatively of which can be resolved by over the counter painkillers. 

 

when can’t root fillings be done?

 

    • If the decay is too extensive.
    • If there is not enough natural tooth left to support a restoration once all the decay is removed.
    • When the old root filling cannot be removed

 

after a root filling:

 

Root filled teeth are often extensively weakened due to the previous dental treatment and routinely require strengthening with a crown.
