Root Canal Treatment

Every tooth contains a soft interior of nerve tissue and blood vessels. When bacteria reach that space through deep decay, a fracture, or a failing restoration, the tissue becomes inflamed and eventually infected. Root canal treatment — also called endodontic treatment — cleans that internal space, shapes and disinfects the canals, and seals them so the tooth can be restored on the outside.

Symptoms that often lead to this treatment

• Spontaneous, throbbing, or lingering toothache, sometimes worse at night
• Prolonged sensitivity to heat or cold that continues after the stimulus is removed
• Pain on biting, or tenderness in the gum near a specific tooth
• A gum bump, drainage, or a bad taste near the tooth
• Darkening of a single tooth, particularly after an old injury
• No symptoms at all — some infections are found only on a radiograph

If pain is severe right now, read the toothache guidance and treat it as an urgent dental concern.

How the appointment sequence usually works

1. Examination, testing of the tooth, and radiographs to confirm the diagnosis
2. Discussion of options, including treatment, extraction, or referral to a specialist for complex cases
3. Local anesthetic and isolation of the tooth
4. Access, cleaning, shaping, and disinfection of the canal system
5. Sealing the canals, then a temporary or definitive filling
6. Final restoration — commonly a dental crown on back teeth
7. A follow-up review of comfort and healing

Honest limitations

Root canal treatment has a good long-term record, but it is not guaranteed. Complex canal anatomy, a vertical root fracture, extensive loss of tooth structure, or advanced gum disease can make a tooth a poor candidate, and some teeth need retreatment or eventual removal. Those possibilities should be discussed before treatment starts rather than afterward.

What affects cost

The tooth involved and the number of canals, whether a specialist is needed, imaging, the final restoration, and dental benefit coverage all influence the total. General drivers are outlined in the dental care cost factors guide. An exact figure requires an examination of the specific tooth.

Frequently asked questions about root canal treatment

Why would a tooth need root canal treatment?

When the nerve and blood supply inside a tooth become inflamed or infected — usually from deep decay, a crack, repeated restorations, or trauma — the tissue cannot heal on its own. Root canal treatment removes that tissue, disinfects the internal canals, and seals them so the outer tooth can be restored and kept in function.

Is a root canal painful?

The procedure is normally performed under local anesthetic, and most people find it comparable to having a filling placed. Discomfort more often comes from the infection beforehand. Mild tenderness for a few days afterward is common; increasing pain or swelling should be reported promptly.

Does a tooth always need a crown after a root canal?

Not always, but back teeth carry heavy chewing loads and are frequently protected with a crown because the remaining structure is weakened. Front teeth with minimal structural loss can sometimes be restored with a filling. The decision depends on how much sound tooth remains.

What is the alternative to root canal treatment?

The main alternative is extraction, followed by a decision about whether and how to replace the tooth. Leaving an infected tooth untreated is not a safe option, because infection can spread and cause worsening pain and swelling.
