Why the inside of a tooth needs treatment
The pulp inside a tooth contains nerves and blood vessels. When it is irreversibly inflamed or infected, treating the outside of the tooth alone is not enough. Deep decay, a crack or an injury can be involved, but your dentist must establish the diagnosis.
Describe when the pain occurs, how long it lasts and whether you notice swelling. Bring any recent X-rays or information from another dentist. The decision also depends on whether the tooth has enough structure and support to function after treatment.
What happens during a root canal
The area is numbed, the tooth is isolated and the affected tissue is removed from its internal spaces. The canals are cleaned, shaped, filled and sealed. Treatment may take more than one visit, depending on the tooth and the situation.
Ask who will carry out the procedure and whether referral to an endodontist is recommended. You should understand both the root canal stage and the restoration that follows it.
The final restoration is part of the plan
A root canal does not replace the missing or weakened outer tooth structure. A filling, crown or other restoration is needed afterward to protect the tooth and restore function. Until that work is complete, follow the instructions about chewing and caring for the temporary restoration.
When comparing estimates, check whether they include only the root canal or also the final repair. Ask how soon the restoration should be arranged and whom to contact if the temporary filling comes out.
Questions about comfort and alternatives
Tell the dentist about previous difficulty getting numb, medicines you take and any concerns about treatment. Local anesthetic is normally used, but no website can predict exactly how your tooth will feel during recovery.
If the tooth cannot be restored, extraction and possible replacement options need to be discussed. Ask about the likely outlook for saving the tooth as well as the consequences of removing it.
Questions patients ask
Will antibiotics replace a root canal?
Medication does not remove damaged tissue or repair the tooth. Your dentist determines whether medication is indicated and what treatment is needed for the underlying problem.
Does the tooth still need care afterward?
Yes. The restored tooth and the tissues around it need regular cleaning and follow-up. Complete the final restoration as advised.
How many visits will it take?
That depends on the tooth, its diagnosis and the treatment plan. Ask about both the root canal appointments and the later restorative visit.
