In this Q&A, endodontic specialist Dr Afzal Haque explains when general dentists should refer root canal cases, key endodontic red flags to look for, and how training, mentorship, magnification, and the right endodontic tools can support more predictable treatment outcomes.
- Not every root canal case needs referral, but complex anatomy, poor canal visibility, large infections, proximity to nerves, previous failed treatment, or challenging patient factors may indicate the need for specialist support.
- Clear patient communication is essential. Dentists should be honest about their experience, explain the risks, and give patients an informed choice.
- Confidence in endodontics can grow through training, practice, mentorship, and observing more experienced clinicians.
- Predictable outcomes start with the basics: appropriate case selection, consistent technique, and a strong understanding of cleaning, shaping, and sealing.
- Investing in quality equipment, including magnification and a reliable file system, can help clinicians improve consistency and treatment outcomes.

How To Improve Endodontic Outcomes, According To A Specialist
Root canal treatment can be one of the most effective ways to preserve a natural tooth, relieve pain, and support long-term oral health. But for general dentists, knowing when to treat and when to refer can be just as important as the treatment itself.
Some endodontic cases are straightforward and well within the scope of a confident general practitioner, but others can quickly become more complex for a multitude of reasons.
Dr Afzal Haque is the Principal Dentist at Stretford Road Dental Practice, an accomplished endodontic specialist, and a Senior clinical lecturer tutor for post-graduate students at the University of Lancashire. With a background in general practice, a master’s degree in endodontology, specialist training at the University of Liverpool, and a Doctorate of Dental Science in endodontics, he brings both specialist expertise and first-hand understanding of the pressures general dentists face when assessing complex endodontic cases.
We spoke to Dr Haque to gain practical guidance and insights on endodontic referral decisions, patient communication, mentoring, and the tools that can help dentists grow their confidence and achieve more predictable clinical outcomes.

What ‘red flags’ should general dentists look out for that may indicate the need for an endodontic referral?
Afzal Haque: There are many different things to look out for that could be potential ‘red flags’ for dental professionals with less endodontic experience. Firstly, the patient themselves could present an issue: they could have high demands or unrealistic expectations, or they could be particularly difficult to anaesthetise.
Common endodontic issues that may indicate a need for referral tend to be things like curvy or hard-to-access roots, canals that are not easily visible on an X-ray, large infections, structures that are particularly close to nerves, or perhaps evidence of previous root canal treatment that has been unsuccessful and could therefore be difficult to redo.

How can dentists communicate referral decisions to patients confidently and informatively?
AH: It’s very important to be honest and upfront. Explain how much endodontic experience you have, and what your skillset is – if the treatment your patient requires isn’t within your skillset, tell them from the very beginning.
If you've done extra training, tell them about that too. Perhaps you have experience tackling more challenging cases even if you’re not an endodontic specialist, but don’t over-promise, and always make sure they are fully aware of the risks. Be open with your patient and give them the choice on how they’d like to proceed – if their expectations are well managed, you shouldn’t have any issues.

From your experience teaching post-graduate dentists, what are the most common challenges clinicians face with endodontic treatment?
AH: Post-graduate students can vary drastically when it comes to their endodontic abilities – some may have many years of experience already. I would say these students are probably harder to teach compared to newly qualified dentists as they may have already adopted hard-to-break habits, and they also may be keen to learn a lot in a very short amount of time.
However, when teaching any post-graduate students, I think the best approach is to go back to basics – whatever their current experience level. Teach them the easy stuff first: make sure they are completely comfortable with less-complex cases and achieving consistent, predictable treatment results before introducing them to more challenging ones.
How can general dentists grow their confidence when it comes to endodontics?
AH: Firstly, post-graduate training is a great way to grow your confidence. Secondly, lots of practice is a must. There's nothing better to practice on than extracted teeth, in my opinion.
If you can, get a mentor, whether that’s your local endodontist or someone within your team who's a bit more experienced than you are. Show them a case you need advice on, go and watch them work, and build strong relationships with them. You’ll learn lots from a textbook or a video, but believe me, you'll learn more by watching somebody doing it firsthand. Pay attention to what sort of methods they use, and ask them questions. If you’re lucky, they might allow you to treat a patient under their supervision.
Which products should all dentists invest in to improve endodontic outcomes?
AH: You’re only as good as your tools, and I believe this is especially true when it comes to endodontics. There are a lot of systems out there that range in cost, and you need to try them and understand the science behind them to really appreciate them. Don’t choose products just because they’re the cheapest.
Quality assurance and consistency are very important, so investing in good equipment can make a big difference to treatment outcomes. Proper magnification is essential: you cannot do endodontics without it. Start with dental loupes, and then work towards buying a microscope when you’re more experienced and ready.
When it comes to sealers, there are lots of newer products that have better properties and can optimise results, but only if you complete the earlier cleaning and shaping stages correctly. Investing in a good file system and practising with it will allow you to deliver successful treatments time and time again.
