A root canal is a treatment that removes infected or inflamed nerve tissue from inside a tooth, then cleans, disinfects and seals it. It saves a tooth that would otherwise need to be extracted. With modern local anaesthetic, most patients say it feels similar to having a filling, and it relieves the pain the infection was causing.
Signs you may need a root canal
- Severe toothache, especially when chewing
- Sensitivity to hot or cold that lingers after the trigger is gone
- A tooth that has darkened
- Swollen or tender gums near one tooth
- A pimple-like bump on the gum
Sometimes there are no symptoms, and the problem is found on an X-ray.
The root canal procedure, step by step
- Numbing. The area is fully anaesthetised.
- Access. A small opening is made in the top of the tooth.
- Cleaning. The infected pulp is removed and the canals are cleaned and shaped.
- Disinfecting. The canals are rinsed to kill bacteria.
- Sealing. The canals are filled with a rubber-like material and the tooth is sealed.
- Restoration. Back teeth usually need a crown afterwards to protect them from cracking.
Treatment takes between one and three appointments of about 60 to 90 minutes each.
Recovery after a root canal
Expect some tenderness for a few days, which over-the-counter painkillers usually manage. Avoid chewing hard food on the tooth until it has its final restoration. Contact us if you have swelling or pain that worsens after three days.
Root canal vs extraction
Pulling the tooth may seem simpler, but a gap leads to neighbouring teeth shifting and bone loss, and replacing it with an implant or bridge usually costs more. Keeping your natural tooth is almost always the better option when it can be saved.
Frequently asked questions
How long does a root-canal-treated tooth last? With a good crown and care, many last a lifetime.
Can I drive home after a root canal? Yes, in most cases, as only local anaesthetic is used.
Will I need antibiotics? Not usually. Removing the infected tissue treats the problem directly.
