Root Canal Fillings
What is a root canal filling?
What is a root canal filling?
In the centre of the healthy tooth is where the tooth’s nerve and pulp lives. When a tooth's nerve and pulp are affected by decay or trauma, bacteria from the mouth can get into this normally sterile area. This then leads to infection and inflammation which can cause pain, and bone loss around the roots of the tooth.
​
The dentist removes the infected tissue in the centre of the tooth, they shape and clean the cavity that is left behind and finally fill the empty space with a special material called gutta percha. This is inert, which means it does not react to the body. This material helps seal the tooth and protect it from future infection. The body’s immune system can then clear up any remaining infection and inflammation so healing can take place.
How would I know if I need a root canal filling?
The common symptoms that the British Endodontic Society advise to watch out for include:
• Intense and enduring pain with hot or cold food
• Spontaneous pain for no reason
• A tooth that is sore to bite on
• The presence of a ‘gum boil’
• Facial swelling
• Tooth discolouration
Sometimes you may have no symptoms, but your dentist finds an area on an X-ray which shows you need a root canal filling.
​
Is having a root canal filling painful?
No. Dentistry should not be painful, and that includes root canal fillings. For a root canal filling treatment your dentist will numb the tooth with a local anaesthetic injection. This makes sure the root canal filling is pain free. Any pain after the treatment can be managed with normal painkillers such as paracetamol.
​
​Why should I have a root canal filling?
A root canal filling doesn’t just preserve the tooth for chewing and smiling, it keeps the bone around the tooth strong, and the neighbouring teeth healthy. If a root canal filling is not possible the only other treatment is for the tooth to be removed.
​
How long do root-filled teeth last?
Studies have shown that approximately 90% of root-filled teeth remain in place for at least 10 years. This is a testament to the effectiveness of modern dental techniques and materials, however it’s important to note that individual results may vary.
​
Factors such as the severity of the tooth decay, the quality of the root canal filling procedure, and proper aftercare can all influence the lifespan of a root-filled tooth.
​
Can all dentists do a root filling?
Root canal filling can be done by any dentist, but back teeth or teeth with complex anatomy may require a dentist with additional training and equipment, or a specialist in endodontics.
The aim is to prevent further damage and pain, so that the tooth can be saved. Keeping your tooth, keeping it strong and healthy along with the neighbouring teeth and bone is well worth it in the long run.
