How Terrible is Plaque?
If the oral cleaning work is not done well, plaque will be formed, and plaque is a comfortable nest of bacteria, which will not only lead to tooth decay and gingivitis, but also may cause myocardial infarction, stroke and other diseases if suffering from periodontal disease.
We use our mouth to taste delicious food, communicate with people and express happiness, anger and sorrow. Our mouth is wonderful and indispensable! But many people may never pay attention. Three meals a day plus snacks, drinks and air in and out just provide enough nutrients for bacteria in the mouth, and in this warm and humid environment, it is conducive to the growth of bacteria. But if you despise oral cleaning and let bacteria grow in your mouth, what terrible sight will it form?
How does plaque form?
According to the research of scientists, there are about 500-700 kinds of common bacteria in the human mouth. Although some of them can coexist peacefully with the human body, some of them will damage the health of teeth and periodontal tissues once they are large. The nest of these bacteria is the notorious “plaque”.
Imagine that when the utensils are left in the sewage for a period of time, a layer of sticky film will form on the surface of the utensils. Similarly, in the poorly cleaned oral cavity, the bacteria take the food residue, the peeling oral cells and the glycoprotein in the saliva as the nutrients, adhere to the surface of the teeth and the gaps and thrive into the pale yellow membrane like colonies, which also forms the so-called dental plaque.
The plaque in different parts of the mouth has different colonies. The plaque in the enamel caries is mainly composed of Streptococcus mutans. In addition to Streptococcus mutans, lactobacillus is also common in the dentin caries, while the plaque in the root caries is mainly composed of radioactive bacteria, and the plaque in the gingival groove is more common, including Clostridium, Gram-negative bacteria, Helicobacter and actinomycete And so on.
Plaque is found in the acidified mouth of food fermentation. There are about 100 million bacteria in a milligram of plaque. If we use such amazing data to estimate, there are about 200-1 billion bacteria in the mouth waiting for opportunities in people with poor oral hygiene habits.
Plaque stacks on the tooth surface and between the teeth. Toxins Secreted by bacteria can also cause a series of immune reactions in the gingival tissue, resulting in gingival, periodontal and dental lesions, and even cause lesions in the oral mucosa and other organs of the body.
- dental calculus
The plaque that has not been removed for a long time will combine with the calcium and other substances in saliva, accumulate at the same time and become hard from the inside. Soon after that, it will become a stone like rough calculus, and after forming, it can not be removed by toothbrush. Dental calculus deposited under the gum is easy to cause more plaque accumulation, which is the main cause of periodontal disease deterioration, and also can cause bad breath.
The food residue is easy to be stuck in the root and seam of teeth, which is often the place where the plaque groups gather and grow. When the power of plaque becomes huge, it will invade the adjacent gingival tissue, resulting in gingival redness and hypertrophy, but the pain is not obvious, so the patients are more unconscious in the early stage, some patients found gingival bleeding when brushing, and they knew they had gingivitis after consulting the dentist. At this time, if we can treat it early and improve oral hygiene thoroughly, gingivitis will have a chance to reverse.
- periodontal disease
Periodontal disease is the pathological change of periodontal tissue (including gingival soft tissue, alveolar bone and periodontal ligament). It will cause gingival atrophy, swelling, bleeding, gaping, teething and so on. In addition to the tooth dropping crisis caused by the foundation shaking of teeth, another problem for patients is that the patients with periodontal disease often have bags formed by the separation of gums and teeth, and the food residues are easy to fall into the bags after eating, in which fermentation and bacteria are encouraged to grow, which makes patients develop a strong halitosis, sometimes even causes bag abscess, inflammation and other situations.
- tooth decay
The bacteria in the plaque and the carbohydrate food attached to the teeth produce a lot of organic acids, destroy the enamel on the surface of the teeth, cause the decalcification of the teeth, and cause cavities. Children’s tooth decay often occurs on the chewing surface of teeth, because they fail to brush away the dental plaque on the groove. The two sides of the crevices are also the places where the common people are prone to tooth decay, because the teeth can not be brushed to these places, so it is necessary to assist with the use of floss or interdental brush to really clear them. As for root cavities, they often occur in the middle-aged and elderly people with periodontal disease, especially in the areas where gingival atrophy causes root exposure. If there is a growth of dental plaque and less saliva, caries cavities will appear rapidly.
- Other diseases
Poor oral health can also affect overall health. In recent years, medical studies have shown that the incidence of myocardial infarction and stroke in patients with periodontal disease is three times higher than that in the general population. If pregnant women have serious periodontal disease, the incidence of premature delivery or low birth weight is 7-10 times higher than that in normal pregnant women. The elderly with poor oral health or periodontal disease are more likely to suffer from aspiration pneumonia. Although the mechanism of action is not clear, the confirmation of correlation has reminded us to keep away from these risks and never neglect oral health.
