With the advancement of economic and health protection awareness, more and more people are paying attention to oral health. The oral cavity plays various important roles such as chewing and swallowing, so oral hygiene is also of utmost importance. When it comes to oral hygiene, the first thing that comes to mind is toothpaste, which can be used for various purposes: whitening, refreshing breath, and so on.

However, selecting the right toothpaste is also an important step in protecting the oral cavity. There are two types of toothpaste that not only do not have a cleaning effect, but may also pose a risk of cancer and harm human health. Today, we will learn about toothpaste and oral hygiene through this article.

Every time we eat,There is always food residue in the gaps between the teeth that we cannot see. These food residues provide abundant food for the bacteria in the mouth to grow. If we don't clean our mouth on time,A large number of bacteria will attach and grow on the tooth surface, gradually developing into plaque. The acid containing metabolites produced by plaque will gradually erode Tooth enamel, thus forming caries, which is also called tooth decay. Therefore, it is necessary to do a good job of personal oral hygiene.

Oral cleaning can remove residual food residue from the mouthThis causes the microorganisms in the oral cavity to lose food and inhibits the growth of microorganisms in the oral cavity. At the same time, oral hygiene can alsoRemove some plaque and soft dirt attached to teeth and gapsFundamentally reduce harmful microorganisms in the oral cavity, thereby protecting our teeth and periodontium. This dual pronged approach canEffectively prevent caries and Periodontal diseaseThe occurrence of.

Meanwhile,Oral hygiene can also effectively alleviate bad breath. The production of bad breath is related to delayed saliva secretion and bacteria in the oral cavity. Anaerobic bacteria in the oral cavity can decompose protein from food residue and necrotic tissue. During the decomposition process,Bacteria produce various unpleasant gasesAmong them, the odor of hydrogen sulfide is the strongest.

The oxygen contained in saliva can inhibit the growth and reproduction of anaerobic bacteria in the oral cavity. WhenWhen saliva secretion is delayed, bacteria will multiply in large numbersProduce many unpleasant gases, which also cause bad breath. Oral cleaning can completely eliminate bad breath caused by delayed saliva secretion, which is due toOral cleaning will remove anaerobic bacteria from the mouthReduce the generation of unpleasant gases.

From the previous text, it can be seen that oral hygiene is very important for maintaining oral health. In the methods of oral cleaningBrushing teeth is a common cleaning method in daily lifeIt is also the simplest and most effective method for controlling plaque. Brushing teeth naturally requires toothpaste, which is a preparation used to assist in cleaning teeth,Mainly plays a role in enhancing the decontamination effect of brushing teeth and eliminating bad breath. The choice of toothpaste can be described as diverse, which can be roughly divided into ordinary toothpaste, medicated toothpaste with special drugs, and fluoride containing toothpaste.

Some toothpastes containing drugs or fluoride can also have a preventive effect on dental caries, but this is only an auxiliary method with limited functionality. becauseToothpaste stays in the mouth for a short period of time and is diluted by saliva, which can cause the concentration of drugs in the mouth to not reach the ideal value for sterilization and cannot effectively prevent caries. And long-term abuse of medicated toothpaste may lead toDestroy the original normal physiological environment and flora colonization in the oral cavity, and interfere with the oral Balance of nature.
