In modern science,
1. “All human indigenous bacteria cannot be classified as good or bad”
2. “There is no technology that can classify the same creatures as good or evil and control/reduce only one or raise/increase only one”
There is a thing.
It is said that about 500 kinds of bacteria, including those that have not yet been named, live in our oral cavity up to 1 trillion.
In modern modern science, identification of bacteria that cause tooth decay and periodontal disease among the indigenous bacteria in the oral cavity is progressing, but
all bacteria in the oral cavity including those that have no name The fact is that the separation of good bacteria and bad bacteria has not actually been done.
In the oral cavity, even indigenous bacteria, which are considered to be good, may have a bad effect depending on the situation (also called opportunistic bacteria), and on the contrary, it is described as a bad one that causes tooth decay and periodontal disease. It has not been scientifically ruled out that indigenous bacteria can also perform good functions such as suppressing bacterial invasion from the outside.
In other words, there are no evidences regarding the judgment of good or evil of indigenous bacteria・Because it has not been clarified.
Next, bacteria are classified as Gram-positive bacteria, Gram-negative bacteria, fungi, etc., and are not classified as good bacteria or bad bacteria.
The latest technology to sort the same organisms as good and bad There is no point.
Like humans, animals, insects, and living things, if you use “poisons”, “insecticides”, and “bactericides”, good and bad people, good animals and bad animals, beneficial insects and pests The indigenous bacteria that form, the bait bacteria and viruses, and the good bacteria and the bad bacteria “act on both at the same time and both.”
The opposite is the same, but since the recent boom in lactic acid bacteria has increased the focus on “bacteria” in the beauty industry, focusing on “beneficial bacteria” and “beautiful skin bacteria” that have a good effect on the human body, the “beneficial bacteria” Even if you want to grow or increase “Beautiful skin bacteria”, “all bacteria including bad bacteria” will increase at the same time.
The following are the current findings in the world’s most advanced lactic acid bacteria research, that is, research on probiotics and lactic acid bacteria antibacterial peptides (bacteriocins).
The antibacterial substances and antibacterial peptides (bacteriocins) produced by lactic acid bacteria vary depending on the type, but there are many antibacterial spectra (ranges) ranging from narrow to wide.
For example, “Nisin A”, which was discovered for the first time in the world and is most famous, has the broadest antibacterial spectrum among lactic acid bacteriocins and controls most Gram-positive bacteria.
On the other hand, bacteriocin, which has a narrow antibacterial spectrum, controls only certain Gram-positive bacteria (Gram-positive bacteria closely related to the production bacteria).
It can be said that this is “a certain bacterium or bacteriocin controls by selecting a specific bad bacterium”, but unfortunately it also works with closely related Gram-positive bacteria. I will.
Among the closely related bacteria of Gram-positive bacteria, Streptococcus mutans which is a bad bacterium that causes tooth decay and selects “only”, “single action” bacteria, substances, and bacteriocins are still found in the world. not.
It is impossible to get rid of only “bad bacteria” among all bacteria.
On the contrary, it is impossible to nourish “good bacteria”, “beautiful skin bacteria” and “only” to give them an advantage and increase “good bacteria”, “beautiful skin bacteria” and “only”.
Health and beauty/moisturizing effect in the oral cavity by growing and increasing “beneficial bacteria” and “beautiful skin bacteria” by paying attention to the existence and effects of “good bacteria” and “beautiful skin bacteria” in the oral cavity and skin I understand that you want to ask for, but unfortunately, you also increase “bad bacteria.”
As an example, if nutrients such as “oligosaccharides” that lactic acid bacteria prefer are given to “good bacteria” and “beautiful skin bacteria”, they will also be nutritious to “bad bacteria”, and at the same time as “good bacteria” and “beautiful skin bacteria” Will increase in the same way.
It is actually difficult to fix new bacteria such as “beneficial bacteria” and “skin-cleansing bacteria” to the human body, and it is not possible to nourish only the “beneficial bacteria” and “skin-cleansing bacteria” that are indigenous to each person. In the end, it means that the bacterial flora composed of “beneficial bacteria”, “beautiful skin bacteria”, “bad bacteria”, etc. will not change, and if you give nutrition, “bad bacteria”, which has a relatively strong power, will also become healthy, We may also expand our power.
In other words, it is impossible for the human body to “control only by selecting bad bacteria” and “increasing only good bacteria and beautiful skin bacteria” with the latest science and technology.
The human beings on earth are the same as we humans, but they support each other, complement each other, act and live together, and coexist in balance.
All of them do not exist insignificantly, and in the situation where their respective functions and interactions are not elucidated in science, it is impossible to distinguish everything from good and evil, and it is not possible to distinguish superiority and inferiority. is.
Even in the same human being, it has been reported that the composition of salivary bacteria varies depending on ethnicity, family, and each person depending on heredity and living environment. For each person, more than several hundred types of oral bacteria are good or bad. It cannot be said that it can be separated into fungi.
The bacteria and flora that we have in the oral cavity, skin, and intestines are not those that we have from birth, but the bacteria and flora that are inherited from parents such as cheek rubbing and saliva contact from an early childhood. It can be said that genetically optimal bacteria protect the body.
Like human beings, living things have good and bad sides for a specific person or society, but they are born and exist because they are necessary, and live and coexist with their individual characteristics.
Invisible to our eyes, it is the same organism, bacteria.
The oral cavity suffers from trouble because it is one of the Gram-positive bacteria, Cariestobacilli, that lives in the mouth as an indigenous bacterium and does not usually cause any problems (it does something useful). Produce acid from food waste and sugar as food to cause dental caries, periodontal disease bacteria that are one of the Gram-negative bacteria “excessively increase” between the teeth to form biofilms, and cause inflammation of the gums. The cause is that it becomes dirty and the total number of bacteria “excessively increases” and flows into the lungs.
Oral care with oral pieces helps to keep the oral health and peace of mind by approaching trouble-causing bacteria that are present as oral bacteria and cause “too many” problems.
