Persistent, sharp tooth pain is one of those things that’s hard to ignore, and when decay has reached deep into a tooth, root canal treatment is often the option your dentist will recommend to resolve it and save the natural tooth.
What a root canal actually involves
Inside every tooth is a soft core called the pulp, made up of nerves and tissue. When decay or damage reaches the pulp, it can become inflamed or infected, which is usually what causes that deep, persistent pain. Root canal treatment removes the affected pulp and replaces it with a filling material, allowing the tooth to be kept rather than extracted.
Signs it might be needed
A few symptoms can point towards needing a root canal, including:
- Ongoing pain, or pain that flares up when eating
- Swelling in the gums or nearby cheek
- Noticeable sensitivity to hot or cold
- Discolouration of the affected tooth
- A tooth that feels slightly loose
Your dentist will usually confirm what’s going on with an examination and X-rays, since some of these signs can point to a few different issues, and imaging helps pinpoint exactly what’s happening beneath the surface.
What happens during treatment
The procedure is done under local anaesthetic, so discomfort during the appointment is generally well managed. Your dentist creates a small opening in the tooth to access the pulp, removes it, then cleans and shapes the canals underneath. These are filled to seal the space, and a temporary filling is placed while things settle. Many teeth are then finished with a crown to restore strength and protect the tooth long term. Depending on the complexity, this can take place over one or more visits.
Recovery afterwards
Some tenderness or mild discomfort in the days following treatment is common, and your dentist will usually suggest sticking to softer foods for a short while as the area settles. Most people find eating feels close to normal again fairly quickly, though it’s worth contacting your dentist if discomfort continues or your bite feels uneven. With good ongoing care, a treated tooth can continue functioning well for many years.
If you’re experiencing tooth pain
Tooth pain that keeps coming back is worth having looked at rather than managed with painkillers alone.
