Few words in dentistry make people wince quite like “root canal”. Say it at a dinner party and someone will clutch their jaw and tell you a story about their uncle in 1987.

Here’s the thing, though. The pain everyone remembers is almost always the toothache that came before the treatment. The root canal is the bit that made it stop.

Modern root canal treatment has very little in common with its old reputation. For most people, it feels much like having a filling, just a little longer. Plenty of patients are genuinely surprised by how relaxed they feel in the chair.

So let’s lift the lid. Below, we’ll walk you through exactly what happens, step by step, with no jargon and no scary surprises. By the end, we think you’ll see root canal treatment for what it really is: a clever way to save your own tooth.

What is a root canal, in plain English?

Every tooth has a hard outer shell and a soft centre called the pulp. The pulp holds the tooth’s nerves and blood supply, and it runs down through thin channels in the roots. Those channels are the “root canals”.

If bacteria reach the pulp, it can become inflamed or infected. That might happen through deep decay, a crack, an old filling that’s leaking or a knock to the tooth. Once that happens, the pulp can’t heal on its own.

Root canal treatment simply removes the troubled pulp, cleans the canals and seals them up. Your tooth stays exactly where it is. It just no longer has a sore, infected centre, so it can carry on doing its job for years to come.

Could you need one? Common signs

Your tooth will usually drop a few hints. Look out for:

  • A throbbing or lingering toothache, especially one that wakes you at night
  • Sensitivity to hot or cold that hangs around for a while after the drink has gone
  • Pain when you bite or chew on one particular tooth
  • Swollen or tender gums near a tooth, sometimes with a small pimple-like bump
  • A tooth that has turned darker than its neighbours, often after an old knock

Sometimes an infected tooth causes no symptoms at all, and we only spot it on an X-ray at a routine check-up. That’s one of the quiet benefits of regular visits. If any of these sound familiar, there’s no need to worry. Just book in so we can take a look and tell you exactly what’s going on.

What Happens During Root Canal Treatment in Folkestone, Step by Step

Most root canal treatments are completed over one or two visits, though a more complex tooth may need an extra appointment. Here’s the journey from start to finish.

Step 1: A proper look first

We start with a chat about your symptoms, then examine the tooth and take an X-ray. This shows us the shape of the roots and how far any infection has spread. We’ll explain what we’ve found, talk through your options and answer every question before anything begins.

Step 2: Getting you comfortable and numb

Next comes a local anaesthetic, exactly like the one used for a filling. We wait until the area is completely numb before going any further. If you’re feeling anxious, just say so. We can take things at your pace, agree on a “stop” signal, and for very nervous patients we also offer IV sedation.

Step 3: Protecting the tooth

We place a small rubber sheet, called a dental dam, around the tooth. It keeps the area clean and dry, and stops any water or solution running into your mouth. Most patients find it makes the whole experience feel tidier and calmer.

Step 4: Clearing out the infection

We make a small opening in the top of the tooth to reach the pulp. Using very fine instruments, we gently remove the inflamed or infected tissue from inside. You’ll feel some pressure and hear a bit of activity, but you shouldn’t feel pain.

Step 5: Cleaning and shaping the canals

This is the careful, detailed part. Each canal is cleaned, shaped and rinsed with disinfecting solutions to flush out bacteria. If the tooth needs more time to settle, we may place a soothing medicine inside and a temporary filling on top until your next visit.

Step 6: Filling and sealing

Once the canals are clean, we fill them with a rubber-like material and seal them, so bacteria can’t get back in. The opening at the top is then closed with a filling.

Step 7: Restoring strength with a crown

A tooth that has had root canal treatment can be more brittle, especially a back tooth that does heavy chewing. In many cases we’ll recommend a crown, a custom-made cap that protects the tooth and restores its natural look. We’ll always explain why before we suggest one.

Does it hurt? Three myths, busted

Myth: “Root canals are agony.” The truth is the opposite. Thanks to modern anaesthetics, the treatment itself should feel no worse than a filling. It’s the infection that hurts, and the treatment is what takes that pain away.

Myth: “It’s better to just pull the tooth.” Your own tooth is almost always worth keeping if it can be saved. A gap can let neighbouring teeth drift, and replacing a missing tooth later usually means more treatment, more time and more cost.

Myth: “Once it stops hurting, I don’t need treatment.” Sadly, a toothache that suddenly disappears can mean the nerve has died, not that the problem has gone. The infection can still be quietly spreading, so it’s always worth getting checked.

After your treatment: an easy recovery

Most people head back to work or carry on with their day straight afterwards. Your lip and cheek may stay numb for a few hours, so wait until the feeling returns before eating or having hot drinks.

It’s normal for the tooth to feel a little tender for a few days. The NHS notes any soreness should settle within a couple of weeks. A few simple tips help:

  • Take paracetamol or ibuprofen if needed, following the packet instructions
  • Chew on the other side until your permanent filling or crown is in place
  • Keep brushing and cleaning between your teeth as normal
  • Come back for any follow-up appointments

If you notice swelling that gets worse, or pain that increases rather than eases, give us a call and we’ll see you.

Root canal or extraction: which is better?

When a tooth is infected, there are really only two options: save it with root canal treatment, or remove it. Root canal treatment is usually successful, and with good care a treated tooth can last for many years, often for life.

That said, not every tooth can be saved. If a tooth is badly cracked or there isn’t enough healthy structure left, removing it may be kinder. In that case, we’ll talk you through replacement options such as a dental implant or bridge. Either way, you’ll get an honest recommendation, never a hard sell.

Frequently asked questions

How long does a root canal appointment take?

Each appointment usually lasts between one and two hours, depending on the tooth. Front teeth tend to be quicker, as they have fewer roots than back teeth.

Can I drive home afterwards?

Yes, after a local anaesthetic you can drive as normal. If you choose IV sedation, you’ll need someone to take you home.

Will I need a crown after root canal treatment?

Often, yes, particularly for back teeth. A crown protects the tooth from cracking and helps it last longer.

Can I go to work the same day?

Most people do. You might just want a quiet lunch while the numbness wears off.
