“Doctor, will the root canal hurt?”
This is probably one of the first questions I hear when I tell a patient that they need a root canal treatment.
And honestly, I understand why.
Somewhere along the way, root canal treatment has developed a reputation for being one of the most painful dental procedures.
But is that really true?
In most cases, no.
In fact, many patients tell us after their treatment, “That was it? I was so scared for nothing!”
So let us talk about what actually happens during an RCT and why it may hurt less than you expect.
Why does a tooth need a root canal?
Inside every tooth is a soft tissue called the pulp. It contains nerves and blood vessels.
When decay becomes deep, or when a tooth has been injured or fractured, the pulp can become inflamed or infected.
This can cause symptoms such as severe toothache, sensitivity to hot and cold, pain while biting, swelling, or sometimes even a bad taste in the mouth.
Once the pulp is irreversibly damaged or infected, simply putting a filling on the tooth will not solve the problem.
That is when a root canal may be recommended.
But will the procedure hurt?
The short answer is that modern root canal treatment is usually performed under local anaesthesia.
The aim is to make the tooth numb before we start treatment.
And if you do feel uncomfortable at any point, you should tell your dentist.
We can pause, reassess the anaesthesia and make you comfortable.
For me, this is an important part of dentistry.
A patient should not have to silently tolerate pain because they think, “Maybe this is normal.”
Tell us.
We would rather know.
Then why do some people say their RCT was painful?
There can be several reasons.
Sometimes the tooth is already severely inflamed or infected before treatment. Such teeth can be more difficult to numb completely.
Sometimes the infection has spread beyond the tooth.
Sometimes the treatment itself is not the reason for the pain. The patient may already have been in significant pain before the appointment.
And occasionally, discomfort can occur after the procedure.
Mild soreness or tenderness for a few days can happen, especially if the tooth was already infected.
That is different from the severe toothache that brought you to the dentist in the first place.
Does an RCT always need to be done in one sitting?
Not necessarily.
Some teeth can be treated in a single visit, while others may need more than one appointment.
It depends on the tooth, the infection, the anatomy of the roots and how the tooth responds to treatment.
What happens if you keep delaying an RCT?
This is something I would not recommend.
If the nerve of the tooth is infected or irreversibly damaged, the problem usually does not simply disappear.
The pain may temporarily reduce because the nerve dies, but that does not necessarily mean the tooth has healed.
The infection can continue and may eventually cause swelling or an abscess.
So if your dentist has advised a root canal, it is better to understand why it is needed rather than simply waiting for the pain to go away.
And one more important thing
Not every toothache means you need an RCT.
Sometimes a tooth hurts because of decay that can still be treated with a filling.
Sometimes the problem is gum related.
Sometimes it is a cracked tooth.
Sometimes the pain is coming from another tooth altogether.
That is why diagnosis matters.
At Feather Touch Dentistry, we prefer to understand the problem first, explain what we see and then discuss the treatment options with you.
Because being told “You need an RCT” is not enough.
You should also know why you need it.
And most importantly, you should be comfortable asking questions.
So, will a root canal really hurt?
So the next time someone tells you, “Root canal means terrible pain,” remember that dentistry has changed a lot.
If you have a painful tooth or have been advised to undergo an RCT, do not let fear alone make the decision for you.
Get it checked. Understand the problem. Then decide how you want to proceed.
