Dental cavities, also known as dental caries in medicine, are a common disease in dentistry. However, dentists often find that some patients, although they brush their teeth carefully and attach great importance to oral hygiene, still have more and more "cavities", and even rampant dental caries. At this time, dentists often recommend patients to go to the rheumatology department for examination, and patients cannot help but ask: Isn't rheumatology department for joint pain? Do you also care about teeth? As everyone has said, joint pain symptoms are indeed common in rheumatic diseases, but rheumatology is actually a general term for a group of rheumatic immune diseases, which often involve multiple organs and present various complex symptoms, even accumulating teeth, eyes, nose, hair, oral mucosa, nails, etc. And the cause of dental caries is due to a disease in rheumatism, which is Sjogren's syndrome. Sjogren's syndrome is a group of diseases mainly characterized by dry mouth, dry eyes, and other symptoms of damage to exocrine glands. Some patients may also experience involvement of multiple systems and organs such as the blood system, lungs, and kidneys, and in severe cases, even threaten their lives. When the glands in the mouth are damaged and unable to secrete saliva normally, the amount of lysozyme present in saliva decreases, allowing bacteria to multiply and causing teeth to be damaged, resulting in the growth of "cavities". This is why dental caries patients need to see a rheumatologist. (New Society)
