The quality and quantity of saliva will affect oral health. Toothache is not a disease, but it hurts like hell. As the saying goes, oral health is related to the quality of life. In fact, in addition to cleaning care, the quality and quantity of saliva will also affect oral health.
The quality and quantity of saliva will affect oral health. 1 "Non-self-cleaning area" is cleaned with saliva.
When it comes to oral health, many people first think of dental health and tooth care actions such as brushing. However, oral health not only includes dental health, but also can not be maintained entirely by brushing teeth and gargling. Saliva plays an important role in oral health.
Experts point out that oral health is related to general health, and oral hygiene is an indispensable part of daily health care.
In order to ensure oral health, it is not entirely possible to brush your teeth and rinse your mouth. Because of gargling and brushing teeth, it is difficult to effectively clean the maxillofacial fossa, adjacent surfaces and the edge of the tooth neck. For example, the pit and fissure of occlusal surface, the gap between teeth and the non-self-cleaning area of gingival margin will accumulate a lot of dental plaque, food residue and soft scale under natural conditions, which will become the most common parts of dental caries and gingivitis, and it is difficult to effectively clean these parts by gargling and brushing.
Saliva can protect teeth.
Brushing your teeth and gargling can't solve the problem, all by saliva. A study shows that speeding up saliva flow can clean up food residues in the mouth more cleanly, and its effect is no less than brushing teeth.
Experts say that saliva often flows in the mouth, which can play the role of mechanical cleaning, enough to reduce dirt and pathogenic factors in the mouth and keep teeth and mouth clean. The increase of saliva secretion can neutralize the acid produced by bacterial decomposition of dental plaque, promote the remineralization of enamel and prevent the occurrence of early dental caries. According to scholars' observation, people with large saliva secretion have lower caries rate.
Besides cleaning and washing, the changes of pH value and calcium content in saliva will also affect the defense against periodontal disease and dental caries.
Chewing massage can promote secretion.
What factors affect saliva secretion?
The quality and quantity of saliva are both important factors affecting oral health, and usually there must be enough quantity to ensure the quality of saliva.
Experts say that there are very few cases of excessive saliva secretion, and it is often insufficient saliva secretion, which is often called "dry mouth". The causes of dry mouth are head and neck radiotherapy, dry mouth syndrome, drugs and diabetes. With the increase of age, salivary glands will degenerate and saliva will decrease. In addition, eating habits will affect the secretion of saliva more or less, and eating hot and sour food will secrete more saliva.
Yu pointed out that there is no harm in stimulating saliva secretion, and some methods to increase saliva secretion can be chosen to maintain oral health, such as increasing chewing and massaging glands. Chewing can stimulate the continuous secretion of saliva and speed up the flow rate, so as to clean up the food residues stranded in the maxillofacial fossa, adjacent surfaces and the edge of the tooth neck, and eliminate the potential threat of risk factors to oral health. You can also massage parotid gland and submandibular gland. Usually massaging these two glands can promote saliva secretion.
The quality and quantity of saliva will affect oral health. The origin of pharynx and body fluid therapy.
The method of swallowing body fluid was first seen in Huangdi Neijing, and it was mentioned in Su Wen's Theory of Acupuncture: "Patients with chronic kidney disease can face south, calm their heart and hold their breath for seven times, so as to lead their throats to be smooth, such as swallowing hard objects. After seven times, the bait will make countless orders to swallow body fluid under the tongue. " People secrete 1~ 1.5 liters of saliva every day. Body fluid, like spring water, is inexhaustible. Therefore, body fluid has many beautiful names, such as Golden Cream and Jade Liquid, Tianchi Water, Golden Jade Liquid and Shenshui.
Why can saliva stay healthy?
Chinese medicine believes that "five fluids are transformed into five internal organs, the heart is sweat, the lungs are tears, the liver is tears, the spleen is saliva, and the kidney is saliva, which is five fluids." It means that saliva is transformed from spleen and kidney, kidney is the innate foundation of human body, spleen is the acquired foundation of human body, and spleen and stomach are rich in essence of five internal organs and flowers of qi and blood, so saliva contains many substances beneficial to human health and longevity, which has special health care function. Ancient doctors used to think that people with full saliva must be strong, and diseases were judged according to the rise and fall of saliva.
Others believe that saliva is a kind of qigong, which contains many profound principles of health preservation. In any case, various practices of ancient health care experts have proved that saliva health care really has a good effect of getting rid of diseases, strengthening the body, prolonging life and beauty beauty.
Modern medicine also shows that saliva contains various components in plasma, as well as more than ten kinds of enzymes and nearly ten kinds of vitamins, minerals, organic acids and hormones. There is also a salivary gland hormone in saliva, which can stimulate human hematopoietic function, delay the aging of various tissues and organs of the body, prevent senile diseases, and benefit people's health and longevity. There is also a peroxidase in saliva, which can inhibit the toxicity of carcinogens. Saliva also has many functions, such as anti-inflammation, detoxification, helping digestion, moistening muscles and losing weight.
According to the research results of the University of Georgia, carcinogenic aflatoxin and nitrite will be diluted and inhibited after 30 seconds of contact with saliva. In other words, saliva has a strong anti-cancer effect and is also a natural anti-cancer agent. In addition, saliva is not only a self-made health weapon, but also a good product for skin care and weight loss because it can remove free radicals harmful to human body from oxygen and food, and contains bacteria that can kill viruses and bacteria. A mouthful of saliva is only 3 ml, but it is often swallowed consciously, which has a good nourishing effect on trachea, esophagus and stomach.
