The causes of tooth infection are varied – deep decay due to cavities or gum disease, cracked fillings or crowns, and damage as a result of trauma, or even teeth grinding. Whatever the reason, a root canal treatment will prevent the need for tooth extraction and future costly treatments.
Root canal symptoms often come in two waves. When the pulp becomes infected, early signs that you might need root canal treatment include toothache, sensitive teeth to hot and cold foods, and pain when eating and drinking. When the infected pulp dies, these symptoms may temporarily subside – but don’t be tempted to put off seeing your dentist! When the infection spreads to the root canal, those early symptoms come back – this time accompanied by pain and swelling to the face and gums, and pus around the infected tooth, which will often appear dark in colour. In this scenario, contact us immediately for an emergency dentist appointment.
Root canal treatment is carried out under local anaesthetic and is usually a straightforward procedure, rather like getting a filling. Once the tooth is completely numb, the dentist will use a series of tiny instruments to open up the tooth and extract the infected pulp. The remaining space is cleaned and shaped, ready for filling with a rubbery substance called gutta-percha. A temporary filling is usually placed on top – the definitive restoration would be carried out in a separate appointment.
You can carry on as normal once the anaesthetic has worn off, though the full healing period will take around a week – just be careful eating and chewing, and maintain an excellent oral hygiene routine.
