Toothache ends here — root canal treatment in Rugby

A root canal takes a tooth that's infected, throbbing and keeping you up at night — and saves it. Done under proper anaesthetic, it feels far more like a long filling than the horror stories suggest.

  • £450–£550 depending on the tooth — exact price in writing before we start
  • Your own tooth saved — not a gap, not an extraction you'll regret
  • In pain now? £50 emergency appointments, usually same-day

Sound familiar?

The ache that paracetamol has stopped touching

It started as a twinge with cold drinks. Now it's a deep throb that wakes you at 3am, you're chewing on one side, and you've caught yourself googling whether teeth can just be pulled out. That pain is usually the nerve inside the tooth — inflamed or infected — and it does not settle on its own.

Left alone, the infection spreads to the bone around the root: an abscess, a swollen face, an emergency. Treated now, the tooth is cleaned out, sealed and kept — and the pain stops.

What actually happens

Three stages — none of them the horror story

1

Numb it — properly

The tooth is fully anaesthetised before anything starts. Most patients say the injection is the only thing they feel all appointment — the relief afterwards is what they remember.

2

Clean out the infection

The inflamed nerve and infection are carefully removed from inside the root, and the canals are cleaned and disinfected — the source of the pain, gone.

3

Seal and protect

The cleaned canals are sealed so nothing gets back in, and the tooth is rebuilt. Back teeth usually need a crown afterwards to protect them long-term — we'll tell you up front if yours will.

Worth understanding

Why we'll usually advise a crown afterwards

A root-treated tooth is out of pain — but it's also more fragile than it was, for three reasons worth knowing before you decide anything:

There's less tooth left

Between the original decay and the access needed to clean the canals, a root-treated tooth has lost a lot of its structure. What remains is a thinner shell — strong enough to work, but with less in reserve.

The warning system is gone

The nerve wasn't just there to hurt — it told you when you were biting too hard. Without it, people unknowingly load these teeth harder than before, and back teeth take serious chewing forces every day.

Cracks, not decay, are the risk

The usual way a root-filled back tooth is lost isn't infection — it's a cusp cracking off, sometimes below the gum where nothing can rebuild it. A fracture like that can undo the treatment you've already paid for.

A crown (£700) cups the whole tooth and holds it together, spreading every bite across the full surface instead of letting forces wedge the weakened walls apart. That's why root-treated back teeth with crowns reliably outlast those without — the crown is what protects the investment you've just made in saving the tooth. Front teeth take much lighter forces, so they can often manage with just a filling — we'll tell you honestly which yours needs, in the written plan, before treatment starts.

The honest bit

Is the tooth worth saving? Sometimes the answer is no.

A root canal only makes sense when the tooth has a future. If a tooth is too broken-down or cracked to last, we'll tell you plainly — because £450 saving a tooth that fails in a year is worse than no treatment at all. Then your options are laid out honestly:

Save it (usually best)

Keeping your own tooth is almost always the cheapest, strongest long-term option — nothing we can make beats a working natural root.

Replace it

If the tooth can't be saved: extraction, then an implant (from £3,000), a bridge or a denture. Dearer — which is exactly why we try to save teeth first.

Complex case?

Some root canals — unusual anatomy, re-treatments — genuinely need a specialist. If yours does, we'll say so and point you to the right person rather than have a go anyway.

Before you book

Root canal questions, answered honestly

Does a root canal hurt?
With modern anaesthetic, no — the tooth is completely numbed and most patients feel pressure, not pain. It's longer than a filling (usually 60–90 minutes) but not more painful. Remember: the agony people associate with "root canal" is the toothache before treatment. The root canal is what ends it.
How much does root canal treatment cost in Rugby?
£450 for front and premolar teeth, £550 for molars (Dental Plan members: £405 / £495). If the tooth needs a crown afterwards that's £700, listed in your written plan up front. 0% finance is available to spread the cost.
Wouldn't it be cheaper to just pull the tooth out?
On the day, yes. Long-term, usually not — a gap lets neighbouring teeth drift and makes chewing harder, and replacing the tooth properly costs far more than saving it: implants from £3,000, bridges from several hundred pounds. Nothing we can make is as good as your own tooth on its own root. That said, if your tooth genuinely isn't worth saving, we'll tell you — not talk you into treatment.
How many appointments will I need?
Usually one or two, depending on the tooth and the infection. Molars have more canals and sometimes need a second visit. You'll know the plan — and the full cost — before we start.
What happens if I just leave it?
The honest answer: it doesn't get better. The nerve dies, the infection spreads into the bone and can form an abscess — facial swelling, antibiotics, emergency appointments — and the tooth usually becomes unsaveable. Toothache that's settled down hasn't healed; it's usually the nerve dying quietly. Sooner is cheaper, in every sense.
Will I need a crown afterwards?
For back teeth, usually yes — and it's worth knowing why. A root-treated tooth has lost structure to decay and treatment, and without its nerve you no longer feel when you're biting too hard — so the most common way these teeth fail isn't re-infection, it's a cusp cracking under chewing forces, sometimes beyond repair. A crown cups the tooth and spreads the load, which is why crowned root-treated back teeth reliably last longer than uncrowned ones. Front teeth take lighter forces and often manage with a filling. We'll tell you which applies to you — with the full cost — before treatment starts.
How long does a root-treated tooth last?
With a good seal and the right restoration on top, many last decades — well-done root treatments have excellent long-term success rates. Normal brushing, hygiene visits and check-ups protect it like any other tooth.
I'm in pain right now — what do I do?
Call us on 01788 579 577 — before 10am gives you the best chance of a same-day emergency slot (£50). We hold emergency appointments every day, and getting you out of pain comes first; the root canal itself can then be planned calmly. More on emergency appointments →

Two ways this goes

You get it treated

One or two calm appointments. The pain stops, the tooth stays, and in a month you've forgotten which tooth it even was. The written plan means no surprises — just an end to it.

You wait it out

The ache fades sometimes — that's the nerve dying, not healing. Then the abscess, the swollen face, the emergency slot, and often a tooth that can no longer be saved. If money's the worry, talk to us about 0% finance — waiting is the expensive option.

No judgement — however long it's been
