alcohol in mouthwash increases the risk of cancer
According to a recent report by the daily mail of the UK, Seymour, a professor of Dentistry at the University of Newcastle, said that many mouthwashes contain alcohol, some as high as 25%. This is mainly to let the menthol, Eucalyptus essence and other ingredients in the mouthwash play a role, and penetrate and decompose dental plaque. However, at the same time, alcohol can also lead to dry mouth, destroy the mucus protective layer that keeps the mouth moist, lead to poor breath, and cause tingling. Some mouthwash can also cause teeth to turn yellow.
In addition, the research report published in the Australian Dental Journal in 2009 shows that alcohol in mouthwash can make carcinogens such as nicotine more easily penetrate the protective layer of the mouth, raising the risk of cancer.
Professor Seymour suggested that doctors should be consulted on which mouthwash to use. For example, doctors may suggest that patients with gingivitis use high fluoride mouthwash. If you don’t have any dental problems, you can use non-alcoholic mouthwash. In addition, it should be noted that the plaque removing ingredients contained in the mouthwash can work within 10 days, and it is not recommended to use them for a long time.
“ glucose chlorhexidine acidate” affects taste
There are many formulations of mouthwash on the market, such as thymol, triclosan, chlorhexidine gluconate, etc. Among them, chlorhexidine gluconate has been proven to effectively inhibit the growth of dental plaque and prevent periodontal disease, but it has also been found that if used for a long time, tooth stains will deposit on the surface of teeth and affect taste. Generally, mouthwash containing chlorhexidine gluconate formula should be used for patients with periodontal disease, oral ulcers or those who have completed oral surgery, but should not be used for a long time to avoid the deposition of tooth stains.
According to the Hong Kong Department of health, most people do not need to use mouthwash, as long as they brush their teeth in the morning and evening and floss. When some people use mouthwash containing alcohol, they may feel dry and uncomfortable in their mouth and lips, or even temporarily lose taste. People who often feel dry in their mouth are advised not to use it.
blindly using mouthwash is not good for oral health.
Mouthwash can freshen the mouth, remove food residues and part of soft dirt in the mouth to a certain extent, and temporarily reduce the number of bacteria in the mouth. The main ingredient of mouthwash is oral freshener, and mouthwash sold in shopping malls or supermarkets is such a product. The main function of this kind of mouthwash is to remove the bad breath of the mouth. It can’t brush away the plaque on the teeth. Food will remain in some small gaps, and it can’t treat periodontal disease and dental caries. In addition, there are also some normal flora in the mouth of healthy people, and many mouthwashes contain anti-inflammatory ingredients to inhibit the continued development of certain oral flora. In this case, the rest of the bacteria in the mouth may continue to increase, resulting in the imbalance of the proportion of human oral bacteria in the natural environment, which is not conducive to oral health.
