Do you have periodontal disease? Periodontal disease is one of the oldest and most prevalent diseases in humans. Currently, the prevalence of periodontal disease among adults in China is as high as 70%, in other words, 7 out of 10 people suffer from periodontal disease, and most of them are unaware of it, and when the symptoms are obvious, the periodontal disease may be in an advanced stage. In the early stages of periodontal disease, there are no obvious conscious symptoms. Occasionally, when brushing the teeth, you may find red and swollen gums or bleeding, but they are often dismissed as “fire”. As the disease worsens, the abnormalities of the gums become more obvious, and patients begin to experience severe bleeding from brushing, receding gums, pus, bad breath, shaky teeth, and other problems.
