Saliva has many functions, so it is an extremely useful substance In addition to playing a role in the digestive process, it is also important for oral health Some animals use their saliva for other purposes For example, swifts use their thick saliva to glue nests together One of the important roles of saliva is lubricant It keeps the oral mucosa moist and comfortable This liquid also lubricates the food in the mouth, making it easier to chew and swallow We've all had dry mouth experiences Without saliva in the mouth, we immediately feel extremely uncomfortable, especially when eating Saliva is composed of many enzymes that perform different functions Lysozyme is an antibacterial agent, so it helps keep oral bacteria at an appropriate level Digestive enzymes such as amylase are responsible for breaking down food before it reaches the stomach and intestines, which helps better digestion and absorption When the enzyme balance is broken, it will lead to health problems, especially the oral bacteria are most common The substance also has a variety of minerals that are usually deposited on teeth, which, in addition to helping keep teeth healthy, can also isolate oral bacteria But in some cases, minerals may accumulate too much and form so-called tartar Digestive enzymes in saliva can help dissolve food residues in the gaps between teeth, ensuring that they do not decay and damage oral health Although saliva has many benefits, it is limited to the mouth Although it has antibacterial properties, it can not be used as an antibacterial agent, because the oral nature is not disinfected Applying it to a wound can cause bacteria in the mouth to enter the bloodstream, which is not what you want Saliva also contains some viruses, which is why kissing patients is not recommended.
