Root canal treatment

About the treatment

Root canal treatment addresses infected or damaged tissue inside a tooth. The aim is to clean and seal the canal system when the tooth can be retained.

When might it be considered?

Persistent pain or sensitivity warrants assessment, but symptoms alone do not establish a diagnosis. Examination, imaging and whether the tooth can be restored are considered.

How is treatment planned?

Following diagnosis and anaesthesia, the tooth is isolated with a rubber dam. The dentist accesses the canals, removes damaged tissue and cleans them using instruments and disinfecting solutions. The canals are filled and sealed; if several appointments are needed, a temporary filling protects the tooth between visits. A final filling or crown restores function and protects the remaining structure.

Aftercare and limitations

Some sensitivity may follow treatment. Retreatment or extraction is necessary in some cases. Check-ups and the final restoration are important for assessing progress.

Timing and costs

Your plan and quotation are determined after examination. Complexity, materials, preliminary treatment and follow-up visits affect timing and cost. Ask for a written plan explaining what is included.

Questions about this treatment

Is treatment complete once the canals are sealed?

The tooth also needs a suitable external restoration. Your dentist explains whether a filling, crown or another option is needed.

Why might retreatment be needed?

A problem may persist or arise after earlier treatment. The canals, restoration and whether the tooth can be preserved are assessed.

Extraction or root canal treatment?

The cause and remaining structure guide the decision. Discuss both the prognosis for preservation and replacement options if extraction is needed.
