If you've been told you need a root canal, you're probably feeling a little nervous and have a hundred questions. Don’t worry—we’re here to explain everything in plain English. Root canals are more common (and far less scary) than most people think.
Here are the top questions people search about root canal treatment—with answers to help you feel informed and confident.
🦷 What is a root canal?
A root canal is a dental procedure that removes infected or inflamed tissue (called pulp) from inside your tooth. The area is cleaned, sealed, and restored—usually with a crown—to save the tooth and stop the pain.
How do I know if I need one?
You might need a root canal if you have:
Persistent toothache, especially when chewing
Sensitivity to hot or cold that lingers
Swelling or tenderness in the gums
A darkened or discoloured tooth
A pimple-like bump on the gum
If you're experiencing any of these, it's worth getting checked by your dentist.
Does it hurt?
This is the #1 fear—but the truth is, a root canal doesn't hurt. With modern anaesthesia, the procedure feels similar to getting a filling. Most patients are relieved that the pain stops after treatment.
How long does it take?
Most root canal treatments take 1 to 2 visits. Each session can last 30 minutes to 2 hours depending on the tooth and how complex the root system is.
Is it better than just pulling the tooth out?
Yes! Whenever possible, saving your natural tooth is the best option. Extracting a tooth can lead to other issues—like shifting teeth, bite changes, and needing implants or bridges, which can be more costly and time-consuming.
Will my tooth be weak afterwards?
Once the pulp is removed, the tooth can become more brittle. That’s why most root canals are followed by a crown to protect and strengthen the tooth for long-term use.
Is a root canal permanent?
When done properly and followed by a good restoration, root canals are highly successful and can last a lifetime. Proper oral care and regular checkups are key.
Can a root canal fail?
It’s rare, but yes—it can happen. If bacteria remain or re-enter the canal, a retreatment or minor surgery (called an apicoectomy) may be needed. This is usually successful.
What can I eat after the treatment?
Stick to soft foods for the first few days—think mashed potatoes, soups, yoghurt, scrambled eggs. Avoid chewing on the treated side until your crown or final restoration is in place.
Can I have a root canal while pregnant?
Yes! Root canals are considered safe during pregnancy. Your dentist will use pregnancy-safe medications and take precautions with X-rays. Always let your dental team know if you’re expecting.
When should I call my dentist?
If you have tooth pain that won’t go away, swelling in the gums or face, or signs of infection, don’t delay. Early treatment means less pain, fewer complications, and better outcomes.
Final Word
Root canal therapy might sound intimidating, but it’s a straightforward, pain-relieving procedure that saves your natural tooth and prevents bigger problems down the track. Don’t put off treatment—let’s get you smiling again.
