Root canal therapy is a very involved procedure completed only by skilled and competent dentists and specialists. It is important to know that root canal therapy is an excellent choice to save your own tooth, with a success rate between 86%-93%. If by chance a root canal therapy fails and you are a good candidate for re-treatment, you will be referred to an Endodontist for retreatment. A root canal therapy retreatment has an excellent success rate of around 73%.
For the best chance of success after a root canal, the tooth must be crowned. Crowns typically last 7-10 years. However, poor oral health habits can cause failure much earlier. Alternatively, excellent oral health habits have seen these procedures outlast the recommended times by years. Some root canal treatments and crowned teeth have lasted people 30+ years.
