Internal resorption punishes complacency. How to catch it on a routine periapical before the crown turns pink.

By Dr John Barclay | GDC No. 210844 | DRJB Smile Clinic, Ruabon, North Wales Non-surgical root canal retreatment resolves the majority of failed endodontic cases. But there is a subset of cases where it either cannot be attempted, has already been attempted and failed, or is unlikely to succeed — and where the choice becomes apical surgery or extraction. Understanding which cases fall into this category, and what apical surgery actually involves, is worth knowing before you r

By Dr John Barclay | GDC No. 210844 | DRJB Smile Clinic, Ruabon, North Wales Root canal treatment saves teeth. The restoration placed afterwards determines whether those teeth stay saved. This is one of the most under-discussed aspects of endodontic outcomes in general practice — and one of the most significant predictors of long-term success. The Evidence Is Unambiguous Studies consistently show that the restoration placed after root canal treatment has a greater influence o

By Dr John Barclay | GDC No. 210844 | DRJB Smile Clinic, Ruabon, North Wales Dental anxiety and endodontic treatment is a combination that warrants specific attention. Root canal treatment carries a disproportionate share of the cultural fear around dentistry, which means anxious patients often arrive for endo appointments in a heightened state — sometimes despite having had straightforward, comfortable treatment before. Managing this well is a clinical skill as much as a com

By Dr John Barclay | GDC No. 210844 | DRJB Smile Clinic, Ruabon, North Wales Complex endodontic cases carry a higher risk of procedural complications than straightforward primary treatment. They also carry a higher medicolegal risk when things go wrong and the documentation doesn't support the clinical decisions that were made. Getting consent and records right in these cases isn't bureaucracy — it's protection for the patient and for you. Here's the framework I use. Why Comp

By Dr John Barclay | GDC No. 210844 | DRJB Smile Clinic, Ruabon, North Wales The endo-perio lesion is one of the most diagnostically challenging presentations in general dental practice. The clinical picture is often ambiguous, the treatment sequence is counterintuitive to GDPs who haven't seen many of them, and the prognosis depends almost entirely on getting the diagnosis right before any treatment begins. Here's the framework I use. The Classification That Matters The trad

By Dr John Barclay | GDC No. 210844 | DRJB Smile Clinic, Ruabon, North Wales The dental operating microscope is not a better way of doing the same thing. It is a different clinical experience entirely — one that changes what you can see, what you can do, and what you can confidently leave alone. Here's what it actually changes, and why it matters for the cases you refer. It Starts With Light, Not Magnification The instinct is to think of the microscope purely in terms of magn

By Dr John Barclay | GDC No. 210844 | DRJB Smile Clinic, Ruabon, North Wales The referral letter is one half of the handover. The conversation you have with your patient before they leave your surgery is the other — and it's the half that determines whether they actually attend, whether they're anxious when they get there, and whether they come back to you afterwards with a good experience or a bad one. Here's exactly what I'd want you to tell them. Why They're Being Referred

By Dr John Barclay | GDC No. 210844 | DRJB Smile Clinic, Ruabon, North Wales A patient asked me recently why I'd suggested emax for her centrals when the composite I'd placed five years earlier still looked, in her words, "perfectly fine." It was a fair question. Here's the answer I gave her, and the framework behind it. Composite and Emax Aren't Competing for the Same Job The mistake — made by patients and, occasionally, by dentists under pressure to close a treatment plan —

By Dr John Barclay | GDC No. 210844 | DRJB Smile Clinic, Ruabon, North Wales There has been no hospital restorative consultant covering this region since 2013. That gap doesn't disappear. It relocates — into general practice, into private referral clinics, and into the hands of clinicians who've had to develop the skills to fill it. Over the last decade, that's what I've done. What follows is an honest account of the case types I accept that often come back to me after being

By Dr John Barclay | GDC No. 210844 | DRJB Smile Clinic, Ruabon, North Wales The terminology is used interchangeably in general practice, and it shouldn't be. Retreatment and re-root canal describe overlapping but distinct clinical situations, and conflating them leads to muddled treatment planning — and occasionally to the wrong decision entirely. Here's how I think about it. The Terminology Problem Root canal retreatment, strictly defined, means the removal of existing root

By Dr John Barclay | GDC No. 210844 | DRJB Smile Clinic, Ruabon, North Wales Referral decisions are rarely black and white. Most GDPs are capable of straightforward root canal treatment. The question isn't whether you can start — it's whether you should finish, and what happens to your patient if it goes wrong. This is the framework I use. It won't suit every clinician, but it might sharpen your own thinking. The Cases You Should Keep If the anatomy is predictable, the access
