What to Expect at a Routine Dental Check-Up

Why routine check-ups are worth the diary entry

A check-up is not simply a quick look at your teeth. It is a chance to catch small problems while they are still small — and cheap and simple to fix. Decay caught early might mean a small filling, or even just a fluoride varnish and some careful monitoring. Left alone, the same spot can grow into something needing a root canal or an extraction.

How often you need to be seen depends on your mouth, not on a fixed rule for everyone. Most adults are placed on a recall of six or twelve months. If your gums are healthy, your diet is kind to your teeth and you have no history of decay, your dentist may suggest a longer gap of up to two years. If you smoke, have gum disease, wear braces or have a dry mouth from medication, expect to be seen more often — sometimes every three months.

Before your appointment: a little preparation goes a long way

There is no need to do anything dramatic, but a few small steps make the visit more useful for both of you:

• Brush and floss as normal before you arrive. There is no need to scrub your mouth into a pristine state — your dentist would rather see it as it usually is.
• Write down anything that has changed. Sensitivity to cold, a twinge when you bite down, bleeding when you brush, a lingering ulcer, a clicking jaw — all of it is useful information.
• Bring a list of your medications, including anything bought over the counter, plus inhalers or supplements. Some medicines cause dry mouth or bleeding gums, and others interact with anaesthetics.
• Know your medical history. Recent surgery, pregnancy, heart conditions, diabetes and allergies all affect what treatment is safe and appropriate.
• Be honest about habits. Smoking, vaping, alcohol, sugary drinks and teeth grinding are not there to be judged — they simply change what your dentist needs to look at more closely.
• Arrive a few minutes early so you can fill in any forms and settle, rather than rushing in flustered.

If you are entitled to free or reduced-cost NHS treatment, bring your exemption certificate or proof of entitlement. If you have dental insurance, check whether you need to do anything before the appointment.

What actually happens in the chair

A typical check-up takes fifteen to twenty minutes. Your dentist will start by asking how you have been and whether anything is troubling you. Then comes the examination itself, usually with a small mirror and a fine probe.

They will look at every tooth in turn, checking the biting surfaces, the edges, the spaces between teeth and any existing fillings, crowns or veneers. You may be offered a scale and polish to remove plaque and hardened tartar, particularly around the gum line. Many practices now use a disclosing solution or a camera so you can see what they see on a screen.

X-rays are not routine at every visit. Bitewing radiographs are usually taken every six to twenty-four months, depending on your risk of decay, and they are the only reliable way to spot decay between teeth or bone loss around the roots. A panoramic X-ray may be taken less often.

Your dentist will also examine your gums gently, measuring the depth of the pockets between your teeth and gums with a probe and noting any that bleed. Healthy pockets measure one to three millimetres. Four millimetres or more suggests gum disease that needs treating.

What your dentist is looking for

• Tooth decay, including early white-spot lesions that can still be reversed with fluoride.
• Wear and erosion, often caused by acidic drinks, reflux or grinding.
• Gum health, checking for redness, swelling, bleeding and receding gums.
• Existing work, such as loose fillings, cracked crowns or a denture that no longer fits well.
• Your bite and jaw joint, looking for uneven wear or tenderness.
• Soft tissues — the tongue, cheeks, lips, palate, floor of the mouth and the lymph nodes under the jaw. This is a mouth cancer screening, and it takes under a minute. A sore or lump that has not healed in three weeks should always be checked.
• Your risk factors, so a sensible recall interval and prevention plan can be agreed.

After the examination: what happens next

Once the examination is finished, your dentist will talk you through what they found. Sometimes the answer is simply "all fine, see you in six months". Sometimes they will suggest a filling, a referral to a hygienist, or a course of treatment for gum disease.

You should leave knowing what is being recommended, why, how much it will cost and what happens if you choose to wait. Ask questions — there is no such thing as a silly one. If a treatment is complex, you are entitled to a written treatment plan and estimate. You can also ask for a moment to think it over; nothing should be done without your agreement.

Keeping your mouth healthy between visits

The best check-up is a boring one. Brush twice daily for two minutes with a fluoride toothpaste, and clean between your teeth once a day with floss or interdental brushes. Cut down on how often you have sugar, rather than just how much — it is the frequency of acid attacks that does the damage. Drink water rather than fizzy or sugary drinks, chew sugar-free gum after meals if you cannot brush, and avoid smoking. If you play contact sports, wear a mouthguard. Do all that, and your next check-up should be quick, comfortable and reassuring.
