At this time, even if you brush your teeth carefully, it may not be clean. Over time, it will pile up with each other and form so-called calculus and tartar. Once dental calculus is formed, it is difficult to remove it. Dental calculus always stimulates oral tissue and leads to inflammation.
Extended data:
The main purpose of brushing teeth is to remove dental plaque, because only dental plaque can form a stable attachment on the tooth surface. Impure substances such as dental calculus and tartar can only stay on the tooth surface through dental plaque, which can cause tooth inflammation, bleeding and even loosening and falling off.
After a meal, about 30 minutes to 60 minutes, dental plaque can form a stable attachment on the tooth surface. Therefore, it is recommended to brush your teeth within 0/5 minutes to 30 minutes after meals, which can effectively prevent the formation of dental plaque without dental calculus and tartar. Most people have only one pair of permanent teeth in their life, and dental caries occur slowly, but they can't repair and regenerate themselves after tooth injury.
Therefore, it is necessary to develop a correct and good habit of brushing and protecting teeth from childhood, and always observe whether the teeth (especially the big teeth at the back are prone to dental caries) are black. If so, it is necessary to deal with them in time, otherwise the dental caries will become more and more serious, and even the teeth need to be filled and extracted.
