It is normal that you will need up to three appointments to complete this treatment.
Your doctor will examine your full x-rays - they will assess how far the infection has spread, whether you have an abscess and also how many root canals your tooth has (front teeth nomally have one root canal but back teeth can have three).

After giving you a local anesthetic, your dentist will place a thin sheet of rubber (called a dam) to separate the tooth from the rest of your mouth. This prevents any spread of infection as well as protecting you from swallowing any small instruments or liquid during the procedure.

An opening will be made in the surface of the tooth and your doctor will gently remove the pulp.

The space in your tooth will be cleaned and sealed - if the treatment is completed then a permanent restoration or crown will be fitted. If more work is required then a temporary filling will be placed to keep it sealed until you go back for the next stage of treatment.
At the next appointment, usually a week later, your dentist will remove the temporary filling and will fill the roots and inside cavity of the tooth with special material called gutta-percha.
Following this, a permanent crown will be fitted.

Post Treatment Care

As the anesthetic wears off, you will regain feeling in your mouth.
It is normal to take painkillers (paracetamol) if you feel any discomfort.
Your dentist will be happy to answer any questions you may have.

You should continue to take care of your teeth by brushing, flossing, healthy diet and of course regular check ups at US Dental Care.


Very occasionally, root canal therapy doesn’t work as expected due to one of the following reasons:

Cracked crown leaking filling material

Curved or narrow canals not treated during the original procedure

Decay in the tooth

Fracture in the tooth

Delay in treating the tooth

Saliva entering the restorative structure

Undetected complex canal structures

If this is the case, the previous crown and packing material must be removed. Your dentist will then clean the root canals and re-pack and re-crown the tooth.

This is generally a better option than extracting the tooth. If the tooth has good bone support, a solid surface and healthy gums beneath it then it stands a good chance of being saved.
