With the vigorous development of the mouthwash market, many citizens who have been plagued by periodontitis and bad breath for a long time began to pay attention to the mouthwash vigorously promoted by bloggers on major live broadcasting platforms, and often asked the doctor: can the mouthwash be used for a long time? Can mouthwash replace brushing your teeth? In this regard, the answer of stomatologists of Guangzhou 12th people's hospital is: it is not recommended to use it for a long time, and it can not replace mechanical cleaning methods such as brushing and flossing. Zhang GeChang, chief physician of Stomatology Department of Guangzhou 12th people's Hospital, introduced that at present, there are roughly two kinds of mouthwashes sold on major platforms and supermarkets—— Pharmaceutical mouthwash Marked by "Xiao", it has medicinal and bacteriostatic properties and needs to be used under the guidance of doctors. If a mouthwash claims to be able to eliminate 99.99% of the bacteria in the mouth, it must be used with caution - the mouth is a mixed environment of various bacteria, and it is impossible to eliminate 99.99% of the bacteria. Even if there is a mouthwash that can eliminate 99.99% of the bacteria, it will also cause the imbalance of the flora in the mouth. Health mouthwash With aromatic agent as the main component, its purpose is to eliminate oral odor. Although this kind of health care mouthwash eliminates the bad breath in a short time, it covers up the truth of the disease - the real causes of bad breath include digestive tract and dental caries. The use of mouthwash is tantamount to treating the symptoms rather than the root cause without going deep into the cause and then carrying out treatment. Moreover, the effect of long-term use of health care mouthwash is not clear, and there is no clinical study to prove that long-term use of health care mouthwash has no side effects. Zhang GeChang said that it is possible to use mouthwash properly, but it should not be abused. Studies have proved that the use of bacteriostatic mouthwash in patients with periodontitis under the guidance of doctors can effectively control subgingival plaque and improve their condition. The use of bacteriostatic mouthwash after mechanical cleaning in patients prone to dental caries can effectively improve the plaque clearance rate. Fluoride mouthwash can not only prevent dental caries, but also resist sensitivity. If you do have bad breath caused by eating heavy smelling food, fragrant non-alcoholic mouthwash can also be used.
