By Dr John Barclay | DRJB Smile Clinic, Ruabon, North Wales The surgery has been here a long time. Long enough that some of the patients who sit in the chair remember my dad sitting in it first — on the other side of it, looking at their teeth, knowing their names, knowing their children's names, knowing who'd had a hard year and who hadn't.

At some point — the details are hazy, possibly suppressed — she caught my ear with the scissors. I have blanked out the specifics.

I avoid the hairdresser to this day.

By Dr John Barclay | DRJB Smile Clinic, Ruabon, North Wales The root canal has a reputation problem. Ask most people what they dread most at the dentist and they'll say it before they've finished the sentence. The thing is, they're describing something that hasn't been true for decades — and possibly never was. Here's what a root canal actually is. What's Actually Happening Inside a Tooth Every tooth has a soft inner core — the pulp — that contains nerves, blood vessels and c

Understanding the Referral Dilemma Referral decisions are rarely black and white. Most General Dental Practitioners (GDPs) can handle straightforward root canal treatments. But here’s the kicker: 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 might not suit every clinician, but it could sharpen your own thinking. So, let’s dive in! The Cases You Should Keep If the an

By Dr John Barclay | DRJB Smile Clinic, Ruabon, North Wales Most people choose a dentist the same way they choose a takeaway. They search, they scroll, they pick whoever's closest with a reasonable number of stars. Nobody reads the reviews properly. Nobody checks the credentials. And then they wonder why they don't feel heard, why they leave confused, or why they eventually stop going at all. Here's what you should actually be looking for. GDC Registration. Non-Negotiable.

By Dr John Barclay | DRJB Smile Clinic, Ruabon, North Wales “It’s not magic — it’s physics, chemistry, and a bit of common sense.” You’ve had your bonding done, you’re grinning at every reflection, and then the question hits: “How long will this last?” The short answer? Usually five years or more — sometimes up to 10 years with care. But longevity depends on you , your bite, and a few everyday habits. 🧠 The Science (Simplified) Composite bonding isn’t a glued-on shell; it’

Small Changes, Big Confidence Miss L, in her early 20s, came to us feeling tired of hiding her smile. She was self-conscious about the small gaps between her teeth. Nothing major, but enough to make her cringe every time a camera appeared. With gentle additive composite bonding , we worked our magic. We closed those pesky spaces and softened the edges.
