Commonly known as root canal treatment, endodontic therapy is concerned with treating the soft tissue inside the tooth.

This area – which is the dental pulp or nerve – can become infected or injured which can result in the natural tooth being lost, sensitivity or discolouration.

You may require root canal treatment to clean or remove the soft tissue to save the tooth and prevent any further problems from occurring.

At Windsor Smiles, we are experienced and advanced practitioners in endodontics and can improve the health of your teeth, bringing an end to the pain and discomfort caused by internal dental infections.

Why you might need root canal treatment

There are a number of reasons that can lead to dental pulp becoming infected or injured, including:

  • Tooth decay requiring deep fillings or restoration work
  • Failure of previous restorative treatments such as crowns, bridges or veneers
  • Trauma to teeth such as cracks or breakage

Treatment is required when bacteria invades and attacks the dental nerve causing infection such as an abscess. If it is left untreated patients can experience swelling, pain and ultimately the nerve of the tooth could die.

Without treatment, there is real risk of losing the tooth and deterioration of the bone.


This delicate procedure helps to eliminate the risk of an infection spreading and functions to remove harmful bacteria which could cause an abscess, tooth discolouration or the loss of a tooth.

If you require root canal therapy, the dentist will ensure the affected area is anesthetised to prevent any discomfort or pain during the procedure.

The treatment entails removing the top of the natural tooth to gain access to the infected dental pulp. This is then cleaned or removed with tiny files and medication is applied to the area to stop any infection spreading. The dentist will end the procedure by placing a root filling in the root and a temporary seal on the tooth. A permanent crown or other form of restorative treatment will be created and fitted once the infection has totally cleared.

Many people feel nervous or anxious about root canal treatment, but at Windsor Smiles, we can assure you that the procedure can be carried out quickly and efficiently to minimise infection and deterioration of the teeth.


An endodontist specialises in advanced forms of root canal disease. At Windsor Smiles we believe in offering the most advanced level of care to all our patients and as such have an in house endodontist. Root canal treatment can fail leading to tooth loss and thus having the most qualified dentist to treat root canal problems is crucial to maximise the success of the treatment and the life of your teeth.

You may also need to see an endodontist if you require advanced endodontic therapy. For example, if there is a problem accessing your tooth’s root, the root canal structure is overly complex, there is excessive root curvature or for various other reasons. Sometime old root canal treatments done years before can fail and get re-infected and an endodontist may be the only kind of dentist that can save your tooth from being lost

Once you have had root canal treatment, there is occasionally a risk of the infection reoccurring. In such cases, a surgical procedure may be required to correct the issue. Where infection is severe, it may be more practical to remove the tooth and replace it with a dental implant.

Very often if back teeth have a root canal therapy they need to be crowned to reinforce and support them and sometimes the teeth go a very dark colour and a veneers or crown is required to hide the darkness. A method called Internal Bleaching is also sometimes performed to help improve a dark tooth.

At Windsor Smile, we will always explain what type of treatment is required and make sure you understand the process ahead.
