Treatment Process

The dentist will initially numb the tooth to be treated using local anaesthetic and isolate the treatment area using a rubber dam. The rubber dam prevents saliva contamination and accidental ingestion of root canal instruments and materials used during the procedure.

The infected nerve of the tooth will first be removed and any abscesses (pockets of pus), if present, will also be drained at this time. The root canal of the tooth is then cleaned and shaped, ready for a temporary filling. During the next visit, the tooth will be permanently filled if there is no signs of infection.

FAQs on Root Canal Treatment

1. How long will it take?
Root canal visits takes about 60 minutes on average and may require multiple visits, depending on the shape and number of canals present as well as the nature of your condition. Front teeth have the advantage of being in a more convenient location and usually have a single large ovoid canal whereas back teeth usually have multiple fine canals which are harder to access. Patients who present with chronic infection, resulting in damage to the surrounding tissues (e.g. sinus tract, cystic changes etc.) should expect a longer follow-up period with their attending dentist. Usually, root canal treatment can be completed in one or two sessions. However, more visits may be required depending on the complexity and severity of the disease.

2. How long will the tooth last after root canal treatment?
With proper restoration, stringent dental care and regular dental checkup, a root canal treatment can last a lifetime. After the completion of a root canal treatment, the dentist will usually advise the patient to go for crowning that can protect the tooth from future fracture.

3. Is the procedure painful?
Root canal treatment does not cause pain and instead relieves pain. When you suffer from a severe toothache, it is likely due to damaged tissues in the tooth. This procedure removes the damaged tissue from the tooth, thereby relieving the toothache. Before treatment, local anaesthetics will be administered to ensure no pain during the procedure.

4. Will there be pain after the root canal treatment?
Patients may feel tenderness after the procedure due to inflammation. Painkillers will be given to the patient to relieve the discomfort the treatment.

5. What is the success rate of root canal treatment?

– The affected tooth develops decay again under the crown due to ineffective oral hygiene
– The tooth cracks due to failure to install a crown
– Severe gum disease develops
