You may have type 2 diabetes
Red, swollen gums that may bleed are the hallmarks of periodontal disease—an incredibly common condition that affects more than 47 percent of Americans 30 and older and more than 70 percent of adults 65 and older, according to the CDC. Periodontal disease is brought on by bacteria in the mouth that infect the tissues and create plaque. "Diabetes makes periodontal disease worse," says Paulo Camargo, DDS, professor of periodontics and associate dean for clinical dental sciences at UCLA School of Dentistry. "Periodontal disease can also make the blood sugar more difficult to control." Research shows that diabetes is a major risk factor for periodontitis, a more serious form of periodontal disease that can damage soft tissues and destroy the bone that supports teeth. In fact, people with diabetes are three times more susceptible to developing periodontitis than those who aren't diabetic. "If gums bleed a lot and are swollen or the patient is having frequent abscesses or infections, the dentist might start to question if you have a family history of diabetes," says Sally Cram, DDS, a periodontist in Washington, DC, and a spokesperson for the American Dental Association. Diabetes isn't the only health problem associated with periodontal disease: The disease, which triggers a harmful, inflammatory response, is also linked to a higher risk of heart attack and stroke. These are other type 2 diabetes symptoms you shouldn’t ignore.
You have acid reflux
Eating garlic knots and forgetting to brush your tongue aren't the only causes of bad breath. In some cases, especially if you already have a solid brushing and flossing regimen in place, a lingering case of halitosis can signal a health problem, such as gastroesophageal reflux disease (GERD). You may not even know you have it since GERD is sometimes a silent condition and can occur during sleep. But over time, GERD can wear away your teeth. In fact, research shows that 24 percent of people with GERD have tooth erosion, which a dentist can easily spot. These are other silent signs of acid reflux you might overlook.
You're majorly stressed out
Grinding or clenching your teeth can be a sign that you're under pressure. These are other signs stress is making you sick. Over time, you can grind down and damage your teeth, causing sensitivity and pain. "You can eventually get to the dentin, under the enamel," says Dr. Camargo. "Your bite height can change and you can create TMJ problems. There's also a risk of fracture—you can break teeth." Another sign of stress? Having a painful canker sore or two. Although the jury is still out when it comes to the exact cause of canker sores, they occur more frequently in people who are stressed, notes Dr. Cram. Although the sores are painful, they're thankfully benign. Try one of these canker sore remedies to make them disappear. That said, if you have a white (or red) lesion in your mouth that doesn't clear up in two weeks, that can be a sign of oral cancer and warrants a doctor's visit and biopsy right away.
Your bone mineral density is low
Loose teeth, including dentures that have become loose, and receding gums can be signs of low bone mineral density, which can lead to osteoporosis. Women with osteoporosis are three times more likely to experience tooth loss than those who do not have the disease, according to the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS). NIAMS suggests that dental X-rays can be used as a screening tool for osteoporosis, noting that research shows dental X-rays are effective in identifying people with osteoporosis compared to those with normal bone density.

You may have an autoimmune disease
If your mouth feels as dry as a desert, certain medications may be to blame, but one possible cause is the autoimmune disease Sjogren's syndrome, which primarily affects women over 40. With the disease, the body attacks the glands that make saliva and tears, causing dryness in the mouth and eyes and increasing the risk of cavities. Although there's no cure for Sjogren's, the symptoms can be managed with treatments that help bring back some moisture. Try out these remedies for dry and irritated eyes.
You're dealing with an eating disorder
Dentists can spot the signs of anorexia and bulimia in their patients. With anorexia, nutritional deficiencies, including a lack of calcium, iron, and B vitamins, can cause tooth decay, gum disease, canker sores, and dry mouth, according to the National Eating Disorders Association (NEDA). With bulimia, stomach acid from vomiting can erode tooth enamel, causing sensitivity to hot and cold food and changing the color and shape of the teeth. In some cases, teeth can become weak enough that they actually break. NEDA notes that redness and cuts along the roof of the mouth brought on by purging is a big red flag for dentists since damage to the soft palate is rare in people who are healthy. Watch out for these silent signs you could have an eating disorder.
You may have celiac disease
According to the National Institutes of Health, dentists are in a unique position to identify celiac disease in patients if they know what to look for. Even though the condition—an autoimmune disease in which gluten damages the small intestine—is associated with gastrointestinal symptoms, celiac disease can also affect the teeth, leading to dental enamel defects. The disease can cause tooth discoloration: namely, white, yellow, or brown spots on the teeth. It can also cause teeth to appear pitted or banded, like a groove going across the teeth. These defects are symmetrical and typically crop up on the incisors and molars. Other oral symptoms of celiac disease include recurring canker sores; a smooth, red tongue (tongues are normally bumpy); and dry mouth. These are other symptoms of Celiac Disease.
