Most people think a dental check-up is the dentist looking at your teeth for two minutes and saying “see you in six months.” That’s the bit you remember. It’s about a tenth of what’s actually happening.
In a proper check-up your dentist is screening for tooth decay, gum disease, oral cancer, jaw issues, signs of grinding, signs of acid wear, signs that you’ve started biting your nails again, and a dozen other things you’d never spot in a mirror. The two minutes of poking is the easy part.
Here’s what’s actually going on, and why the half hour you put off matters more than you think.
Cavities are the smallest part of the appointment.
When the dentist runs a metal probe across your teeth, they’re not just looking for holes. They’re feeling for soft spots in the enamel: early decay, before it goes deep enough to show on an X-ray. A filling caught at this stage takes 20 minutes and lives in the tooth invisibly. The same cavity missed for a year becomes a root canal.
That’s the trade. A check-up is the early-warning system. Once you can feel a problem, you are past the cheap, quick, comfortable stage of fixing it.
Gum disease is the silent half.
Around half of UK adults have some degree of gum disease. Most don’t know: gums bleed a bit when you brush, and you assume that’s normal. It isn’t.
During a check-up your dentist measures the pocket depth between each tooth and the gum. Healthy pockets measure around 1–3mm. Anything over 4mm suggests active disease. Caught early it is a hygiene appointment and a change to how you brush. Left alone it is the most common reason adults lose teeth.
What we look for, in order.
Every check-up at Believe Dental follows the same six steps, in the same order, every time, so nothing gets missed.
- Soft-tissue screen: cheeks, tongue, palate, throat. Looking for ulcers that haven’t healed, white patches, lumps. This is the oral cancer check.
- Teeth: every surface of every tooth, with mirror and probe. Cavities, fractures, wear patterns from grinding.
- Gum pocket depths: measured with a small probe, tooth by tooth, alongside the bleeding-on-brushing picture you describe.
- Notes from last time: anything we said we would keep an eye on, and any new signs of clenching.
- Existing work: old fillings, crowns, bonding. Are they lifting, cracked or discoloured.
- Bite check: how your teeth meet, any jaw joint signs, any sign you grind at night. Your bite tells us where the pressure is going.
X-rays are taken when they are needed rather than routinely, and they look between the teeth and below the gum line. That is the territory a visual check cannot reach.
Why six months?
Because that is roughly how long it takes for decay to progress in someone with average habits. If your risk is higher — a lot of sugar in the diet, a history of gum problems, a dry mouth caused by medication — we shorten the interval. If your risk is low, we may lengthen it. The interval should be a clinical decision about you, not a default.
If the dentist itself is the barrier.
We see this every week. Someone knows they should book a check-up, but the idea of sitting in the chair is worse than the guilt of not going. If that is you, book a consultation instead. It is a chat first: no drill, no examination, no pressure.
Start with a chat. Not a chair.
Book a consultation. No exam, no pressure. Just an honest conversation about what you need and what you are worried about.
