Frequently Asked Questions About Root Canal Treatment

1. How do I know if I need a root canal?

Persistent toothache, prolonged sensitivity to hot or cold, pain while chewing, deep decay, gum swelling, or tooth discolouration can indicate pulp damage. However, these symptoms do not confirm that an RCT is necessary. A dentist must examine the tooth and assess the findings before recommending treatment.

2. Can a tooth need a root canal without severe pain?

Yes. Some teeth with pulp damage or infection may produce mild symptoms or no noticeable pain in the early stages. This is why dental examinations are important, especially if you have deep decay, a cracked tooth, or a history of dental trauma.

3. Is root canal treatment better than tooth extraction?

When a tooth can be restored, root canal treatment may help preserve the natural tooth and its chewing function. Extraction may be necessary if the tooth is too damaged to repair. Your dentist can explain the benefits, limitations, and alternatives based on the condition of your tooth.

4. Can root canal treatment be completed in one sitting?

In suitable cases, root canal treatment can be completed in a single appointment. However, some teeth require multiple visits depending on the extent of infection, the complexity of the root canals, and the treatment response. Your dentist will advise you on the appropriate schedule.
