The short version
- UK private root canal: roughly £250–£700 (front tooth) to £500–£1,000+ (molar) — before the crown.
- Bulgaria: typically ~£100–£250 per tooth, with a zirconia crown around £410.
- On the NHS, root canal treatment is Band 2 — £76.60 — if you can get an appointment. Honest answer: that's the cheapest route if it's available to you.
- Travelling makes sense for root canal + crown, multiple teeth, or as part of a bigger plan — rarely for one root canal alone.
Few phrases empty a wallet faster than "you need a root canal" at a private UK practice — especially when it's a molar, and especially when the quote arrives with a crown attached. A single back tooth can reach £1,000–£1,500 all-in privately. Here's what the same treatment costs in Bulgaria, and an honest look at when travelling for it adds up.
What a root canal actually is
Root canal treatment (endodontics) rescues a tooth whose nerve has become infected or died — usually from deep decay or trauma. The dentist removes the infected pulp, cleans and disinfects the canals inside the root, and seals them. Because a root-treated tooth becomes more brittle, back teeth almost always need a crown afterwards to protect them. That crown is often the biggest line on the bill — and the part people forget to compare.
Root canal cost: NHS vs UK private vs Bulgaria
| Treatment | NHS (England) | UK private | Bulgaria |
|---|---|---|---|
| Root canal — front tooth | £76.60 (Band 2) | £250–£700 | ~£100–£180 |
| Root canal — premolar | £350–£800 | ~£130–£220 | |
| Root canal — molar | £500–£1,000+ | ~£150–£250 | |
| Zirconia crown (usually needed after) | £332.10 (Band 3) | £600–£1,200 | ~£410 |
| Molar root canal + crown, total | £332.10* | £1,100–£2,200 | ~£560–£660 |
*On the NHS the crown moves the whole course into Band 3, one combined charge. NHS molar root canals are frequently referred or unavailable in practice — availability is the honest catch.
The honest comparison
If you have an NHS dentist who will do the work, use the NHS. £332.10 for a root canal and crown together is a price no amount of travel can beat, and we'll never pretend otherwise. The problem — as anyone who's tried recently knows — is that NHS appointments for complex molar endodontics are hard to find, and many practices refer these cases privately.
If you're facing private UK quotes, the picture changes. A molar root canal plus crown at £1,100–£2,200 in the UK costs roughly £560–£660 in Bulgaria — a saving of £500–£1,500 on one tooth. If two or more teeth need treating, or the root canal sits inside a larger plan of crowns or implants, the saving typically covers the whole trip several times over.
Rule of thumb: one root canal alone — stay home. Root canal plus crown at private UK prices — the maths starts working. Multiple teeth or a bigger plan — the maths works comfortably. Send us your UK quote and we'll show you the comparison line by line.
What treatment looks like in Bulgaria
A straightforward root canal takes one or two visits of about an hour, under local anaesthetic — modern rotary instruments and digital imaging have made the procedure far quicker and more comfortable than its reputation suggests. If a crown is needed, the tooth is prepared and scanned, and the final crown is usually fitted within the same 5–7 day stay.
One honest caveat: if there's a significant active infection, a good dentist may want it settled with antibiotics before completing treatment, or may stage the work across two visits. The right clinic plans around your tooth, not your return flight — and that's precisely the kind of clinical judgement we look for in the clinics we recommend.
Frequently asked questions
Why are root canals so expensive privately in the UK?
Molar root canals are genuinely time-consuming — often 1–2 hours across one or two visits, frequently referred to a specialist endodontist, and usually followed by a crown to protect the tooth. Specialist time plus a crown is how a single back tooth reaches £1,000–£1,500 privately in the UK.
Is a root canal done abroad safe?
The procedure is the same everywhere: remove the infected pulp, disinfect the canals, seal them. Bulgarian dentists train to EU standards and good clinics use the same rotary instruments and imaging you'd see in a UK practice. As with anywhere, the skill of the individual dentist matters most — which is why clinic vetting matters more than the country.
Can a root canal and crown be done in one trip?
Often yes. A straightforward root canal can be completed in one or two visits, and many clinics then prepare and fit the crown within the same stay of roughly 5–7 days. If there's an active infection that needs to settle first, an honest dentist may stage it differently — the timeline should follow your case, not the flight schedule.
Is it worth travelling for just one root canal?
On its own, usually not — an NHS Band 2 root canal at £76.60 is far cheaper than any trip, if you can get an NHS appointment. Travel starts making sense when you're quoted privately for a root canal plus crown, or when the root canal is one item on a longer treatment plan. We'll do the maths with you honestly before you book anything.
