Dr Catherine Nestor has completed 2 years in postgraduate training for root canal treatment and will answer any questions you may have about root canal treatment.

What is Root Canal Treatment?

Root canal treatment involves removing the nerve from your tooth. It is a common dental procedure that is used to save your painful or infected tooth. People often worry about this procedure but here at Merrion Road Dental we can assure you it is usually a straightforward painless procedure. The appointment is just a little longer than getting a filling. It is a safe and efficient procedure to help save your tooth for aesthetics and function.

Why Root canal treatment?

If the nerve is dead, then it must be removed as it can cause an infection and a swelling. This can happen due to decay, truama, general wear, fracture.


  • Local anaesthetic is given

  • We access the nerve through the core of the tooth.

  • We clean, shape and enlarge the roots. A filling material is placed into each root.

  • Usually, a crown is required following root canal treatment to strengthen the tooth and protect the tooth from fracture.


*We recommend placing a crown on all posterior teeth that have been root canal treated within 4 months to increase the long-term prognosis of the tooth.

How will you feel post root canal treatment?

Patients may feel some pain for short while post root canal treatment. A painkiller may be required as the tooth settles down. Paracetamol and ibuprofen are the most prescribed painkillers. A discomfort is normal but if this continues, please ensure to contact.


Usually, the time flies by during root canal treatment and we advise to bring your headphones and listen to a podcast or music.
