What happens during a dental checkup

The examination

Your dentist will look closely at each tooth, your gums, your tongue and the soft tissues of your mouth. A typical exam includes:

1. Checking each tooth for decay, cracks and worn or loose fillings.
2. Measuring the small gaps between your gums and teeth to look for signs of gum disease.
3. Looking at your bite and how your jaw opens and closes.
4. Screening the lips, tongue, cheeks and throat for anything unusual, including early signs of oral cancer.

X-rays and when you need them

X-rays show what cannot be seen by eye: decay between teeth, problems below the gum line and the health of the bone. You will not need them at every visit. Many adults with healthy teeth have them every one to two years, while people with a history of decay may need them more often. Modern digital X-rays use a very low dose of radiation.

The cleaning

A hygienist or dentist removes plaque and tartar with small hand tools or an ultrasonic scaler, then polishes your teeth to remove surface stains. It may feel a little scratchy, but it should not hurt. If your gums are sensitive, tell them and they can slow down or use a numbing gel.

After your checkup

Before you leave, your dentist will explain what they found and whether you need any treatment. Ask them to show you on the X-ray or a mirror if anything is unclear. You should also leave with a clear plan for when to come back.

Key takeaways

• Checkups find problems early, often before they cause pain.
• A visit usually includes a health chat, an exam, a cleaning and sometimes X-rays.
• Most people need a checkup every six to twelve months; your dentist will advise what suits you.
• Tell your dentist about your medicines, habits and any worries before treatment starts.
