Root Canal Treatment

Root canal treatment, also known as endodontic therapy, is a dental procedure used to treat infection at the center of a tooth (the root canal system). It's a vital procedure that can save teeth that might otherwise have to be removed. This blog post will explain what root canal treatment is, why it's needed, and what you can expect during the procedure.

Cos'è il trattamento canalare?

Root canal treatment is performed to remove infected material and relieve pain from a tooth that has been severely affected by decay, disease, or injury. The treatment involves removing the damaged area of the tooth (the pulp), cleaning and disinfecting it, and then filling and sealing it to prevent further infection.

Why is Root Canal Treatment Needed?

The need for a root canal usually arises from a bacterial infection that has penetrated through the tooth's enamel and dentin into the pulp, where nerves and blood vessels are located. Causes of root canal infection include:

  • Deep decay: caused by untreated cavities.
  • Repeated dental procedures: on the same tooth that can cause wear and infection.
  • Crack or chip in the tooth: which can expose the pulp to bacteria.
  • Trauma: such as a physical blow to a tooth, which can cause pulp damage even if the tooth has no visible chips or cracks.

Symptoms Indicating a Root Canal is Needed

  • Severe toothache pain upon chewing or application of pressure
  • Prolonged sensitivity or pain in response to hot and cold temperatures
  • Discoloration (darkening) of the tooth
  • Swelling and tenderness in the nearby gums
  • A persistent or recurring pimple on the gums

The Procedure for Root Canal Treatment

1. Diagnosis and X-ray: The dentist will take X-rays to see the shape of the root canals and determine whether there are any signs of infection in the surrounding bone.

2. Anesthesia: The area around the tooth is numbed with local anesthesia to ensure comfort during the procedure.

3. Pulpectomy: An opening is made through the crown of the tooth to the pulp chamber. Diseased pulp is removed, and the root canals are cleaned and shaped for filling.

4. Filling: The cleaned and shaped canals are filled with a biocompatible material, usually a rubber-like material called gutta-percha, and sealed with an adhesive cement.

5. Restoration: After the root canal therapy, the tooth is restored with a crown or filling for protection and will continue to function like any other tooth.

Dopo cura

After treatment, your tooth may be sensitive for a few days due to natural tissue inflammation, especially if there was pain or infection before the procedure. This discomfort is usually manageable with over-the-counter pain medications. It’s important to follow your dentist's instructions and avoid chewing on the treated tooth until it's fully restored to minimize further damage.


Root canal treatment is a highly effective procedure with a success rate of over 95%. It's one of the best methods to save a tooth that might otherwise need to be extracted. By treating and saving a natural tooth, a root canal can help maintain your oral health and prevent the need for more invasive dental procedures in the future. If you're experiencing symptoms of a root canal infection, consult your dentist promptly for evaluation and treatment.
