A root canal treatment is carried out when ‘the pulp’, the innermost part of the tooth becomes badly decayed or infected. The pulp is also known as the nerve of the tooth. If left untreated, the tooth will begin to die which could lead to infections, abscess and the loss of the tooth. To save the tooth, the infected pulp needs to be removed to prevent the formation of an abscess.
The tooth is made up of
- Enamel – The hard outer layer of the tooth. One of the hardest materials in your body!
- Dentine – This forms the core and gives the basic shape to the tooth which supports the enamel, it is softer than enamel but harder than bone.
- Pulp – Is the central part of the tooth which contains nerves and blood vessels and lies within the root canal.
The reason the pulp would die
- Caries aka Tooth Decay – If caries/tooth decay is left it will get bigger and bigger until it travels through the enamel and dentine down into the pulp chamber.
- Cracks – a Crack in an otherwise healthy tooth can travel into the pulp and disturb it.
- Trauma – A severe knock that affects the pulp of the tooth.
- Severe Gum Disease – The gum detaches itself from the tooth creating a gap between the tooth and the gum, bacteria then gets trapped causing an infection within the pulp chamber.
- Pain – This can be anything form a constant dull ache to severe pain or pain only when biting.
- Sensitivity to hot or cold food/drinks. Temperature changes until trigger the infected pulp to ache and cause pain.
- A spot sometimes appears on the gum in the area of the infected tooth. This is commonly an Abscess where the collection of pus from the root tip is draining which will leave a bad taste in your mouth.
- Swelling in the gum area surrounding your tooth.

On your initial appointment the dentist will locate the offending tooth and take an x-ray in order to examine the roots of the tooth, to see how far the decay has traveled and if there is an abscess present.
the first appointment
- The dentist will give you a local anaesthetic to numb the tooth and the area surrounding it.
- Your dentist has to gain access to the pulp chamber.
- Once access has been gained to the pulp chamber, the dead pulp is removed from the root canals are cleaned and washed. This is to remove all the infection present in the tooth and surrounding areas.
- Once the root canals are cleaned the dentist will place a medication inside the tooth to help clear any bacteria. The tooth will be filled with a temporary filling and another appointment required or if the infection was not too serious, the tooth can be filled permanently and your treatment complete.
- The tooth may feel tender for a few days and you may need to take pain killers
- A course of antibiotics may be given to clear the abscess if it is very serious. Commonly treatment alone is enough to sort it out however.
if a second appointment is necessary
- You will be given a local anaesthetic to numb the tooth and the surrounding tissue.
- Your temporary filling will be removed.
- The dentist will continue cleaning out the canals using the same process as before. Once the canals are clean and dry they will be filled with a material called ‘Gutta Percha’ which is placed into the root canal to ensure a perfect seal.
- An X-ray is then taken to check that the canals have been filled completely.
- A permanent filling will then be put in place.
- Your dentist may advise you to have a crown placed on the tooth to strengthen it.
