In a healthy tooth, the roots are surrounded by strong gums and other supporting tissues. Periodontal disease is a disease of the tissues surrounding the teeth, and the soft tartar and tartar on the surface of the teeth are the main places for bacteria to live. Periodontal disease begins with bacterial infection of the gums, after which the bacteria further invade the deeper supporting tissues. As these tissues weaken, become infected and destroyed, healthy teeth become loose and fall out. Progression of periodontal disease: Periodontal disease may not have any symptoms, so it is not easy to alert you. It asymptomatically destroys the supporting tissues of the teeth. Gingivitis can progress to periodontitis or advanced periodontitis if left untreated. Early treatment makes it easy to manage periodontal disease, while also helping to restore oral health and protect teeth. Clinical signs of gingivitis: Red, swollen, sore or bleeding gums or bad breath, plaque and tartar on the gums and teeth. Gaps will appear between the gums and teeth. Gingivitis is recoverable and the alveolar bone will not be damaged. Clinical manifestations of periodontitis: When gingivitis spreads to the alveolar bone, it will develop into periodontitis. Plaque and tartar appear under the gums. They irritate the gums, which appear red and congested, bleeding gums, and receding gums. The periodontal ligament breaks down and the gums and teeth separate. Periodontal pockets deepen and become filled with more bacteria. The alveolar bone begins to break down and the teeth become loose. Lifelong maintenance of periodontal disease: Periodontal disease is usually in a progressive state, so a lifelong treatment plan is needed to control it. After a thorough evaluation, your doctor will recommend the best treatment option for you. Whether this approach is non-surgical or surgical, it includes home health care. There are many types of bacteria that exist and grow in a healthy mouth. Some bacteria cause decay, others form a colorless sticky film on top of the teeth and gums that can be removed by proper flossing and brushing. If plaque is not removed regularly, it will calcify and become tartar. This yellow or brown rough deposit is more difficult to remove than plaque, and the bacteria attached to plaque and tartar cause periodontal disease, and only by removing them can periodontal disease be prevented from worsening or recurring. You should visit a professional hospital in time and have your teeth scaled regularly to remove tartar. This way you will have a healthy mouth.
