Root canal treatment

We are here for you at every step


Root canal treatment is used to treat infection at the centre of a tooth. The treatment is not painful and can save a tooth that might otherwise have to be removed completely.

Before appointment:

  • We will assess your tooth in detail to see if a root canal treatment is appropriate. An X-ray will be useful to aid assessment
  • We will discuss alternatives to root canal treatment and their merits and drawbacks with you. The alternatives are extraction and replacement or root canal treatment with a specialist [endodontist]. While no treatment is an alternative, it will not be advisable
  • We will also advise you of risks, complications and success rates so that you are completely informed before going for treatment. We will provide you a consent form which will have the list of all the possible complication that could happen. You can read it and ask questions and we will ask you to sign it before we proceed with the treatment.

During appointment:

  • Your tooth will be numbed using local anaesthetic injection so that it is a pain-free procedure for you.
  • Once the area is numb, we will drill the tooth, remove the infected nerve, clean the nerve space and prepare it for filling
  • Next, we will place the root filling and then fill the tooth on top.
  • Throughout the treatment, we will need to place a rubber sheet around tooth to help make the treatment comfortable for you and easy for the dentist as well.

After treatment:

  • The treated area will be numb for several hours after the procedure. After the numbness wears off, you may feel pain or soreness in the treated area. Please take paracetamol if needed, the pain or soreness should gradually go down after 24 hours.
  • You may experience some swelling or bruising, which can take a couple of weeks to heal completely. If you are at all concerned, please call us and we can give you appropriate advise and see you soon if necessary.
  • If needed, we will book a follow up appointment for you to fit a Crown or cap to help strengthen your teeth.


It is a common misconception that root canal filling hurts. Your dentist will make your tooth completely numb before starting the procedure. If you are experiencing any discomfort during the procedure, please report to your dentist, it should be dealt with before continuing the procedure.

Root canal treatments are done to save the teeth. If that’s not possible or it is something that you do not want, the other option can be extraction (taking the tooth out under a local anaesthetic).

Teeth can take few days to few weeks to start feeling comfortable again. Although you would not feel it but the healing at the end of root can take up to a couple years. Your dentist might take X-rays during your routine check-ups to monitor the healing.

You tooth can sometimes discolour over time. If this becomes a concern, please make an appointment and we will discuss the options to treat that.
