Root Canal Treatment: Common Questions Answered

Root canal treatment, also called endodontic treatment, is used to treat the inside of a tooth when the pulp has become inflamed or infected. This article answers common questions in general terms. An examination and, where appropriate, X-rays are needed before a dentist can confirm the cause of symptoms or recommend treatment.

For information about assessment and treatment at our private Worthing practice, see our root canal treatment service page.

What symptoms should be assessed?

Persistent toothache, pain when biting, prolonged sensitivity to hot or cold, swelling, tenderness, or a tooth that has become darker can have several causes. A cracked or heavily filled tooth can also need assessment. These signs do not by themselves confirm that root canal treatment is required.

How is the need for root canal treatment assessed?

A dentist will ask about symptoms, examine the tooth and surrounding tissues, and may use tests and X-rays. The findings help identify whether the pulp is inflamed or infected, whether the tooth is restorable and what options are reasonable. Suitability can only be confirmed after examination.

What happens during root canal treatment?

Root canal treatment removes inflamed or infected tissue from inside the tooth. The canals are cleaned, shaped and disinfected before being filled and sealed. A temporary or permanent restoration may be placed as part of the plan. The exact approach depends on the tooth and its condition.

Will root canal treatment hurt?

Local anaesthetic is normally used to make treatment more comfortable. Sensations vary, and the tooth may feel tender afterwards. Tell the clinician if you feel uncomfortable. The practice will explain what to expect and provide aftercare advice for your situation.

How many appointments will be needed?

The number and length of appointments depend on the tooth, its anatomy, the extent of infection, whether it has been treated before and the restoration required. One or more appointments may be needed. Timing is confirmed after examination and may be reviewed as treatment progresses.

Can root canal treatment always save the tooth?

No. Treatment aims to retain the tooth where this is clinically appropriate, but not every tooth can be treated or restored. Cracks, remaining tooth structure, gum and bone support, canal anatomy and response to treatment can affect the outlook. Further treatment, referral or extraction may sometimes be needed, and success cannot be guaranteed.

What happens after root canal treatment?

The tooth may need a filling or crown to restore it and reduce the risk of fracture. Follow the personalised aftercare advice provided and attend any planned review. Contact the practice if symptoms worsen or you are concerned after treatment.

How much does root canal treatment cost?

Our Fees page lists the current fee for root canal treatment. A filling or crown may be needed afterwards and is usually priced separately. The final treatment plan and cost depend on examination, X-rays where appropriate, complexity and the restoration required. Costs will be explained before treatment is agreed.

What alternatives might be discussed?

The options depend on the diagnosis and condition of the tooth. They may include monitoring, a different restoration, root canal treatment, referral, or extraction with or without a later tooth-replacement discussion. A dentist will explain the relevant benefits, limitations and costs before you decide.
