The doctor introduced as follows:
The establishment and maturation of dental plaque, that is, "bacterial community", need to go through three stages:
First of all, the nutrients in saliva are adsorbed on the tooth surface, which constitutes the fertile "soil" of the "community", that is, the formation of the acquired membrane. This process can be formed in a few minutes on the freshly cleaned tooth surface, and it becomes thicker rapidly in 1-2 hours.
After the formation of "soil", it can attract bacteria to settle down and provide nutrition for bacteria, that is, bacteria adhere and gather. First, pioneer bacteria will settle down, reclaim the soil and establish the infrastructure of the community, and then more other bacteria will be attracted to settle down, and a "new community" will be born.
If there is no man-made destruction, the "emerging community" will soon develop into a "mature community", that is, the patch is mature. Many bacteria gather together to provide nutrients to each other and absorb nutrients from saliva at the same time. Bacteria multiply in large numbers, and the structure of the "community" is more compact, which can resist external interference and can not be removed by gargling. Generally, it can develop into a complex and mature "community" with various bacteria in 9 days.
