If you’ve just been told by your dentist that you need a root canal, your first reaction is probably relief that your tooth can be saved — quickly followed by the question everyone asks next: how much is this actually going to cost? It’s a fair question, and one that’s surprisingly hard to get a straight answer to. Prices vary a lot between practices, and very few dental websites actually tell you what to expect before you’ve already booked a consultation.
If you’re based in East London, this guide breaks down exactly what affects the price of a root canal, what you should expect to pay, and what questions to ask before you commit to treatment.
What Is a Root Canal, Exactly?
A root canal is a procedure that removes infected or inflamed pulp from inside a tooth — the soft tissue containing nerves and blood vessels — and then cleans, shapes, and seals the empty space to stop the infection from coming back. It’s typically needed when decay has gone deep enough to reach the nerve, when a tooth has been cracked or injured, or when a previous filling has failed and allowed bacteria back in. Left untreated, this kind of infection doesn’t resolve on its own; it tends to get more painful and can eventually lead to an abscess.
The good news is that root canal treatment has a very high success rate and, done properly, allows you to keep your natural tooth for years, sometimes decades, rather than losing it altogether.
What Actually Determines the Price
There isn’t a single flat fee for “a root canal” because not all teeth are the same. Front teeth, known as incisors, generally have a single root canal and are the most straightforward and least expensive to treat. Premolars, just behind them, often have two canals. Molars — the larger teeth at the back of your mouth used for chewing — can have three or even four canals, which takes considerably longer in the chair and involves more precision, and is priced accordingly.
There’s also a difference between a first-time root canal and a retreatment. If a tooth has already had root canal treatment in the past and the infection has returned, retreatment is more technically demanding — the dentist has to carefully remove old filling material before addressing the new infection — and this is typically priced higher than a first-time procedure.
In and around the E16 area, root canal treatment generally starts from the mid-£300s for a straightforward single-canal front tooth, rising toward £700–£900 or more for complex molars or retreatments. Getting a clear quote after an initial examination, rather than a vague estimate over the phone, is the best way to know exactly where your case falls.
Is a Root Canal Worth the Cost Compared to Extraction?
It’s tempting to think extraction is the cheaper option, since it can sometimes cost less upfront than saving the tooth. But that comparison rarely holds up once you look further down the road. A missing tooth needs to be replaced to keep your bite functional and stop your other teeth from shifting out of position — and replacing it with a dental implant, bridge, or denture typically costs significantly more than the root canal would have in the first place. Keeping your natural tooth also preserves your natural bite force and appearance far better than any replacement can.
What Actually Happens During Treatment
Root canal treatment has a reputation for being painful, which is largely outdated. Modern local anaesthetic numbs the area completely before any work begins, and most patients say the experience feels very similar to having a large filling done — some discomfort in the days afterward as the area settles, but not the ordeal it’s often made out to be.
During the appointment, the dentist removes the infected pulp, then carefully cleans and shapes the inside of the root canal to remove all traces of bacteria. Once it’s fully disinfected, the canal is filled and sealed, and in many cases the tooth is then protected with a crown to restore its strength, particularly for back teeth that take the most chewing pressure.
Do You Need an Emergency Appointment?
If you’re in genuine pain — throbbing, swelling, or sensitivity that’s getting worse rather than better — this isn’t something to sit on. Same-day emergency root canal appointments are available at practices equipped to prioritise urgent cases, and getting seen quickly not only relieves pain sooner but often prevents the infection from progressing to the point where the tooth becomes harder to save.
Questions Worth Asking Before You Book
- What’s the exact price for my specific tooth, not just a general range?
- Is a crown included in the quote, or is that billed separately afterward?
- What happens if the treatment needs a second visit?
- Is there a payment plan available if I’d rather spread the cost?
A practice that answers these clearly, before you’ve committed to anything, is generally a good sign of how transparently they’ll handle the rest of your treatment.
