When you think of a dental exam, you probably think of a quick check for cavities and a professional cleaning. While these are a crucial part of every appointment, a comprehensive dental exam is actually a window into your overall health. Therefore, your dentist is a detective, using the clues in your mouth to spot potential issues that extend far beyond your teeth and gums. Consequently, the list of what dentists can detect is truly surprising.

Here are seven surprising facts about what dentists can detect during a routine exam:
1. Signs of Stress and Anxiety
Do you find yourself clenching your jaw during the day or grinding your teeth at night? This condition, known as bruxism, can be a symptom of stress and anxiety. For instance, your dentist can spot the tell-tale signs of bruxism, such as worn-down teeth and jaw pain, and may recommend solutions like a custom night guard to protect your smile.
2. Vitamin and Nutritional Deficiencies
Your diet has a direct impact on your oral health. In fact, a lack of certain vitamins and minerals can manifest in your mouth in surprising ways. For example, bleeding gums could signal a vitamin C deficiency, while a smooth or burning tongue might be a sign of iron deficiency. Ultimately, your dentist can identify these subtle clues and recommend that you consult with your primary care physician. What dentists can detect extends to nutritional clues.
3. Osteoporosis
This condition, which causes bones to become weak and brittle, often goes unnoticed in its early stages. However, a dental X-ray can provide a crucial early warning. As a result, the X-rays may reveal a loss of bone density in the jaw, which can be an early indicator of osteoporosis.
4. Diabetes
The link between oral health and diabetes is well-documented. For this reason, people with diabetes are more susceptible to gum disease, and in turn, severe gum disease can make it harder to control blood sugar levels. Your dentist can, therefore, look for signs like swollen, bleeding gums, dry mouth, or a “fruity” breath odor, which may indicate uncontrolled blood sugar.
5. Gastrointestinal Issues, like GERD
Gastroesophageal Reflux Disease (GERD) is a condition where stomach acid flows back into the esophagus. Furthermore, this acid can also make its way into the mouth, eroding tooth enamel. A dentist is consequently trained to recognize the specific pattern of tooth erosion caused by acid reflux, which is often on the back surfaces of the teeth.
6. Oral Cancer
Early detection is key to successfully treating oral cancer. Accordingly, during a dental exam, your dentist will perform a thorough screening, checking your lips, tongue, cheeks, and other oral tissues for any unusual growths, lumps, or sores. As a result, this routine screening is a simple yet life-saving part of your regular check-up. What dentists can detect through this screening is vital.
7. Inconsistent Oral Hygiene Habits
Your dentist can tell if you’ve been flossing daily or just for the week leading up to your appointment. In fact, signs like plaque buildup and inflamed gums are clear indicators of your at-home oral care routine. Moreover, a dental professional can also offer personalized tips and techniques to help you improve your daily habits and maintain a healthy smile. The full scope of what dentists can detect is quite remarkable.
