Saliva — colorless liquid, which consists of salivary gland secretion, released into the oral cavity. Saliva moistens the mouth, allowing articulation does taste brighter, softens chewed food. In addition, saliva also has other properties: it cleans the mouth from germs, food debris and prevents the teeth from damage.
It should also be noted that under the action of salivary enzymes begin to digest carbohydrates cavity.
What saliva consists of
It is known that saliva 98.5% is water and also includes various acid salts, and cations of certain elements of alkali metals, lysozyme, vitamins and so forth. «PRIZMA» Aesthetic Dentistry Clinic specialists argue that the composition of saliva may influence the state and dental health. Saliva proteins have (salivoprotein) that contribute to the deposition of fosforokaltsievyh compounds on the teeth, and calcium-binding protein (phosphoprotein), because of which is formed tartar and plaque.
Quantity and chemical composition of the saliva depend on the type of food consumed, and on its release rate (e.g., if you eat candy, the saliva is increased glucose levels that are harmful to the tooth enamel). Do not forget that in the composition of saliva affects the age — the older the person, the greater the calcium that promotes the formation of tartar.
When such disease is periodontitis, comprising saliva decreases the amount of certain substances needed by the human body. This reinforces the pathological phenomena occurring in the teeth.
Ultimately, changes in the composition of saliva and a decrease in the number of its results in digestive disorders and poor dental health.
As saliva influences on the health ofteeth
Saliva facilitates entry of calcium, phosphorus and other minerals in the tooth enamel, so has a great influence on the state of tooth enamel, including on its resistance to the development of caries.
Reducing the amount of saliva (xerostomia) leads to dryness of the mouth, difficulty in speaking and swallowing food, contributes to damage tooth tissues and so forth. Xerostomia reduces defenses saliva. Reducing the amount of saliva may also occur in consequence of the reception of certain drugs (allergies, colds, depression, and drugs for the regulation of blood pressure and so forth.).
To avoid damage to the teeth, which is applied during sleep due to a decrease of saliva, specialists clinic of aesthetic dentistry «PRIZMA» is recommended before going to sleep necessarily brushing and special thread to reduce the amount of plaque. You should also drink plenty of fluids.
Saliva — excellent protection of teeth from decay. It contains antibacterial substances that prevent the multiplication of microorganisms, and neutralizes acid. With age, the solubility of enamel is reduced, since it is constantly fed with saliva, and this in turn reduces the risk of developing caries. Treat carefully to their health, take care of it!
