If your dentist just told you that you need a root canal, you probably felt your stomach drop a little. Root canals have a reputation problem — they’re the punchline for “worst thing ever,” even though most patients who’ve actually had one say it felt about the same as getting a filling. Here are honest answers to the questions we hear most often, from people sitting in that exact chair.
Root Canal FAQs
What is a root canal, exactly?
It’s a procedure that removes infected or inflamed tissue (called pulp) from inside a tooth, cleans out the empty space, and seals it back up. The goal is simple: save a tooth that would otherwise need to come out because the infection has reached its nerve.
How do I know if I need a root canal?
The most common signs are a lingering toothache (especially one that throbs or keeps you up at night), sharp pain when you bite down, sensitivity to hot or cold that hangs around after the trigger is gone, and swelling or a pimple-like bump on the gum near the tooth. Sometimes there’s no pain at all and it only shows up on an X-ray — that’s why regular checkups matter.
Does a root canal actually hurt?
This is the big myth. The infection is what hurts — the root canal is what relieves it. You’re numbed the same way you would be for a filling, and most patients describe the appointment as no worse than getting a cavity filled. Any soreness afterward is usually mild and manageable with over-the-counter pain relievers for a day or two.
What actually happens during the appointment?
After numbing the area, your dentist creates a small opening in the top of the tooth, removes the infected pulp with fine instruments, cleans and disinfects the empty canals, then fills and seals them. A temporary or permanent filling closes the access hole. Most root canals take one to two visits depending on the tooth and how complex the canals are.
How long does the procedure take?
Usually somewhere between 60 and 90 minutes for a single visit, though molars with multiple canals can take a bit longer or need a second appointment.
What’s recovery like afterward?
Most people are back to normal activities the same day. It’s common to have some tenderness or mild soreness for a few days, especially when chewing near that tooth — that’s just the area healing, not a sign anything went wrong. Avoid chewing on that side until any temporary filling is replaced with a permanent restoration.
Do I need a crown after a root canal?
Often, yes — especially on back teeth that do a lot of chewing work. A root-canaled tooth can become more brittle over time since it no longer has a live blood supply, and a crown protects it from cracking. Your dentist will tell you whether your specific tooth needs one.
What happens if I just skip it?
The infection doesn’t go away on its own. It can spread to the bone around the tooth, cause a painful abscess, and eventually the tooth may need to be extracted instead — which usually costs more in the long run and means replacing the tooth with an implant or bridge. Treating it early is almost always the simpler, less expensive path.
How much does a root canal cost?
It varies quite a bit depending on which tooth is involved (front teeth have fewer canals than molars) and whether a crown is needed afterward. The most reliable way to get a real number is a quick exam and X-ray — we’re happy to walk you through the cost before any work starts, and we accept most PPO insurance plans.
Is a root canal better than just pulling the tooth?
In most cases, yes. Saving your natural tooth keeps your bite, jawbone, and the alignment of neighboring teeth intact. Replacing a pulled tooth with an implant or bridge is typically a longer, more involved, and more expensive process than a root canal plus a crown.
