Diseases that a Good Dentist can Detect [List]

Since our mouth is the gateway to our health, it only stands to reason that our dentist may be the first to notice something’s wrong. In fact, a dentist can detect signs of more than 100 diseases during a routine oral exam. That’s one reason dental professionals and the American Dental Association encourages everyone to get them every six months.


It’s been suggested that over 90% of all systemic diseases have symptoms that appear in the mouth, such as ulcers, swollen and bleeding gingiva, dry mouth, discolored teeth, or bad breath. A couple examples include bone loss found during x-rays, sour jaw could hint at an oncoming heart attack, or crumbling teeth can be a sign of malnutrition or an eating disorder.

If you have any of these symptoms or are worried about your health, asking your dentist at the next exam is perfectly acceptable. Their professional opinion or recommendations can lead to catching diseases and disorders before they progress to destructive stages and treating them with less intrusion or pain.

As with all health issues, the best medicine is prevention. Keeping yourself in good overall health will not only prevent these diseases but keep your mouth in good standing as well. A regular oral care routine includes brushing for two minutes twice daily, flossing once daily, and seeing your dentist twice per year. In addition, rinsing with fluoride-based mouth rinse and chewing sugar-free gum can help keep your mouth clean between brushings and prevent the symptoms above.
