Today, we pay special attention to clean, whether it is their own or home. We often clean, wipe, purify every corner of the house. The benefit of doing so is to help prevent the spread of bacteria and viruses and keep us healthy. So we always consider how to wash your hands can reduce the spread of the disease, or brush your teeth to improve oral health.
Although these clean is so important, but we are not a bit too much? Some scientists think that we clean so clean, in fact, weakened the body's defense system. In fact, the presence of some bacteria just give us some of the immune system exercise opportunities, let it build its own powerful "fortress". Imagine your immune system is a guard of the castle, when the fallen guard faces a group of invaders, it will be unable to fight back. However, if the guards have the experience of counting countless enemies on a regular basis, then it will be better against these invaders. So, our immune system needs to keep training and prepare for combat.
We have other methods that may also hinder our immune system. For example, the use of certain antibiotics (antibacterial) products sometimes cause excessive performance of the immune response. Mouthwash in a component - triclosan, has been concerned by some medical experts, it is not only in the mouthwash, and sometimes appear ye toothpaste and soap. Researchers at Johns Hopkins University have found that long-term use of high levels of triclosan may lead to antibiotic resistance in the body.
Probably most people do not know what is triclosan? It is understood that triclosan is a broad-spectrum antimicrobial agent, generally added in toothpaste, soap, deodorant, mouthwash, shaving cream and other daily necessities. In 2009 published in the new national standard toothpaste, triclosan was included in the allowable addition of preservatives, but clearly not more than 0.3%. However, healthy people's mouth there are some normal flora, long-term use of sterilization effect of drug mouthwash, it will lead to a certain type of bacteria are over-suppressed, resulting in oral flora, but not conducive to oral health.
For the average person, if you get up every day and before going to bed with fluoride toothpaste to completely clean the teeth, you do not need to use fluoride or anti-tooth film mouthwash. Therefore, antibacterial mouthwash should be used with caution because they also eliminate "good" bacteria and use mouthwash at the same time to understand the possible negative effects they may bring. Mouthwash in addition to containing triclosan, some also contain alcohol, alcohol has a role in solubilization, can help dissolve the mouthwash used in the fat-soluble ingredients, and alcohol also has the ability to sterilize, it is widely used. It is certain that alcohol can lead to dry mouth, destruction of the oral mucus to protect the moisturizing layer, resulting in poor tone, and lead to tingling. A study shows that the use of mouthwash to eliminate healthy oral bacteria, but also make blood pressure. Mouthwash can not replace brushing. Also can not be used frequently, up to 3 times a day, otherwise it will inhibit the normal number of bacteria in the mouth, a serious cause of oral fungal lesions, leading to mouth sores.
If you really like to use mouthwash, then you need to make sure that triclosan does not exist when you buy it and other products. The Department of Health said that most people do not need to use commonly used mouthwash, as long as morning and evening brushing, and the use of floss cleaning is sufficient.
