7 Things You Didn’t Know Your Dentist Does at Your Checkup

When you go in for your routine dental checkup, you probably expect the usual—some scraping, polishing, and maybe a reminder to floss more often. But your dentist is doing a lot more than just cleaning your teeth. Behind the scenes, each checkup is packed with small but important steps that help protect your oral and overall health. Here are 7 things you may not realize your dentist is doing during your visit.

1. Checking for Oral Cancer

One of the most important (and often unnoticed) parts of your exam is an oral cancer screening. Your dentist looks for any unusual lumps, bumps, or discolored patches inside your mouth, on your tongue, and along your cheeks and gums. They may also feel your neck and jawline for swollen lymph nodes. Catching oral cancer early greatly increases treatment success.

2. Examining Your Jaw and Bite

Dentists don’t just focus on teeth—they also evaluate how your upper and lower jaws come together. Subtle misalignments in your bite can lead to headaches, tooth wear, and even TMJ (temporomandibular joint) problems. Your dentist may ask you to open and close your mouth, listening and feeling for signs of joint stress.

3. Looking for Early Signs of Gum Disease

Even if your gums don’t hurt, your dentist checks for inflammation, redness, and recession. They may use a small probe to measure the depth of the spaces between your teeth and gums. Early gum disease can be reversed with better home care and professional cleanings before it turns into more serious periodontitis.

4. Tracking Tooth Wear and Cracks

Your dentist keeps an eye out for signs of teeth grinding (bruxism) or enamel erosion from acidic foods and drinks. They may notice small cracks, chips, or thinning enamel that you haven’t felt yet. Addressing these early can prevent more serious problems like tooth fractures or sensitivity.

5. Checking Old Dental Work

Fillings, crowns, and bridges don’t last forever. Your dentist examines your past dental work to make sure it’s still secure, functional, and free from decay underneath. This step can save you from sudden pain or unexpected repair costs later.

6. Evaluating Your Tongue and Soft Tissues

Your dentist inspects your tongue, the roof of your mouth, the insides of your cheeks, and even your lips for sores, infections, or other issues. Many systemic health problems can show early signs in the mouth, including vitamin deficiencies, autoimmune conditions, and diabetes.

7. Checking Your Breathing

You may not notice it, but your dentist can sometimes detect signs of sleep apnea or chronic mouth breathing during an exam. This is often based on wear patterns on your teeth, dry mouth symptoms, or the shape of your airway.


A dental checkup is much more than a quick clean. It’s a full-mouth health screening, early warning system, and preventive care session rolled into one. Knowing what your dentist is looking for can make you appreciate just how much they’re doing to protect not only your smile but also your overall well-being.
