Endodontics deals with the inside of the tooth. Root canal treatment may be proposed after an exam when the pulp is affected; the diagnosis decides whether it's needed.
When is a root canal needed?
Root canal treatment means cleaning, disinfecting and then filling the canals inside the root. It may be indicated for deep decay, severe or lasting pain, an abscess or trauma. The aim is to keep the tooth rather than extract it.
Using a microscope
An operating microscope gives magnification and light that improve visibility inside the tooth. It helps locate canals, check the cleaning and retreat a tooth that has already had a root canal. It's used when the case calls for it and doesn't replace the clinical and X-ray examination done first.
After treatment
A root-treated tooth is more fragile, so a solid restoration, sometimes a crown, is often recommended. X-rays are used to monitor healing. Come to the follow-up visits and contact the clinic if symptoms persist or get worse.
Frequently asked questions
Does a root canal hurt? It's done under local anaesthetic. Some sensitivity can last a few days afterwards.
How many sessions does it take? One or several, depending on the infection, the shape of the canals and the tooth.
Can a root canal be redone? Yes. Retreatment can be offered if a treated tooth becomes painful again or shows infection. The assessment decides whether it's feasible.
