Is the “carcinogenic” charge of mouthwash possible?

Some people say that a kiss is a big exchange of 80 million bacteria in the mouth, and it is like a crowd of people during the Spring Festival….

Some people say that a sneeze shoots nearly 1 million droplets. And the speed of droplet spraying is very fast. It can fly out of 4.6 meters in less than 1 second, and the number of bacteria that can be sprayed by a sneeze can reach 85 million.

You think that your mouth is very clean. Actually, it is not.

According to the British “Daily Mail” report, through the microscope observation of the teeth, you will find numerous bacteria and more dirty substances on it.

(PS: Is it OK to be a tooth surface? It’s so colorful~)

In the past, people thought that brushing their teeth sooner or later could meet the hygiene standards, but it was not enough for the new concept of oral hygiene. Experts suggest that cleaning the mouth is as necessary as washing hands. However, it is unrealistic to take out toothpaste and toothbrush anytime and anywhere. At any time , it is possible to include a toothpaste and then vomit it. The mouthwash can then come forward and bear heavy burdens.

Mouthwash is peppermint, ice blue, orange, cherry blossom… It sounds like someone looking for Kiss. But as much as the taste of mouthwash is its “rumor.” For example, long-term use of mouthwash can cause cancer. Mouthwash can cause dysbacteriosis. In one word, do not use it often. However, is this true?

1. First, let’s take a look. With mouthwash and no mouthwash, where is the difference?

Before discussing this issue formally, we first clarify the concept of “mouthwash”. Mouthwash can be divided into two types. One is prescription mouthwash. This type of mouthwash can prevent and control periodontal tissue inflammation. It is mainly used for periodontal disease and oral mucosal disease. It is generally not used at will. Since it is for the dentist to prescribe, it will not be counted as the scope of today’s discussion. The other is over-the-counter mouthwash, which is what people often see in advertisements, the kind that is bought in supermarkets, and today we mainly discuss this kind of “over-the-counter mouthwash”.

Why use mouthwash? The steps for perfect oral care should be: brush your teeth, use dental floss (dental retraction should also use an interdental brush), and then use a mouthwash.Conventional brushing only removes 40% to 50% of the plaque on the tooth surface. Using dental floss to clean the adjacent surface can only remove 30% of the plaque. However, these are basically ineffective for removing plaque on the oral soft tissue surface. The function of the mouthwash is just to further remove the plaque on the surface of the tooth and soft tissue.

In some occasions eating, some “heavy taste” foods such as onion, garlic, etc. (not to say “I eat garlic is the predestination of the northerners”), making people “to stop.” At this time, there is a small bottle of mouthwash in the bag, so you can refresh your breath. Mouthwash can also take care of elderly people who have lost their teeth, children who do not brush their teeth, and those who cannot tolerate dental problems.

However, mouthwash can not be used as a substitute for brushing. A simple mouthwash can’t clean teeth like a mechanical physical way of brushing teeth, which is also a need to be clear.

To sum up, mouthwash can not only help you resolve blemishes in key situations, but also refresh your breath, prevent and control rickets, reduce plaque, slow down the rate of tartar formation, and prevent and reduce gingivitis. However, mouthwash can not replace brushing.

2. Are all the legendary mouthwash hazards “convicted”?

After clarifying that you are going to use mouthwash, and that mouthwash can’t replace toothbrushing, let’s take a look at the dangers of mouthwash if it’s a crime!

Conviction 1: Long-term use of mouthwash can cause oral cancer.

“Some studies have found that using a mouthwash more than three times a day has a cancer risk. Because mouthwash contains a lot of alcohol, staying in the mouth for a long time will make alcohol become acetaldehyde and threaten oral health.”

First of all, let’s look at the most horrible crimes and cause cancer. This is mainly due to the fact that the mouthwash contains some alcohol. Some mouthwashes contain 20-25% alcohol and taste very spicy. Together with the alcohol will have some “dehydration” effect, for a long time will make the mouth feel dry. However, it is attributed to cancer, we will discuss and discuss.

The authors of Pandanet.com have stated that this problem has been debated for many years in the academic community. Alcoholism has been proved to be one of the risk factors for the development of oral cancer, and because mouthwash contains alcohol, it is further used as a mouthwash. Will be “carcinogenic.” There were also studies that determined the acetaldehyde content in saliva after using alcohol-containing mouthwashes and found that acetaldehyde did increase. But so far, no study has really confirmed the link between mouthwash and oral cancer risk.

Most users of mouthwash do not reach the high frequency of using more than three times a day. It will not let the mouthwash “stay in the mouth for a long time” because no one will have mouthwash every day. In other words, instead of worrying about mouthwash, it is better to be more vigilant about the exact risk factors for oral cancer such as smoking, drinking alcohol, and chewing betel nuts.

Therefore, there is insufficient evidence that “the use of mouthwash for a long time will lead to oral cancer” and the charge is not established. Of course, just in case, Dr. Xu Tongyi of the Peking University Stomatological Hospital recommends that high-risk groups avoid the use of alcohol-based mouthwashes, including children, drunkards, and poorly conceived alcohols. The next).

The second charge: the use of mouthwash can cause oral flora imbalance.

“Pharmaceutical mouthwashes should not be used arbitrarily. Long-term use of such mouthwashes can cause imbalances in the normal flora of the oral cavity and drug resistance, and can even cause allergic reactions, which can reduce taste buds and suppress the secretion of saliva.”

First of all, this refers to “pharmaceutical mouthwash,” which is not part of our discussion of “non-prescription mouthwash.” The therapeutic mouthwash contains anti-inflammatory and bactericidal drug ingredients such as chlorhexidine and compound iodine, and long-term use of the mouthwash can actually cause dysbacteriosis. However, ordinary mouthwashes do not have too many pharmaceutical ingredients. The basic ingredients include water, alcohol, detergents, flavoring agents, and pigments.

Complaint 3: Use of mouthwash will make the teeth black.

“I used my mouthwash and found that my teeth were darkened.”

This situation is common in “therapeutic mouthwash.” Chlorhexidine gluconate (chlorhexidine) proved effective in inhibiting the growth of dental plaque and preventing periodontal disease, but at the same time it was found that if used for a long time, dental stains will deposit on the surface of the teeth and affect the taste. However, mouthwash, which contains chlorhexidine gluconate, is usually given to patients with periodontal disease, oral ulcers, or who have undergone oral surgery. For “over-the-counter mouthwash”, although looking at the colorful, just adding some pigment, it will not stain on the teeth.

Therefore, the charge was only established for mouthwash containing ingredients such as “chlorhexidine,” and it was not established for most over-the-counter mouthwashes.

For those “hazards” of mouthwash, “prescription mouthwash” and “over-the-counter mouthwash” also need to be distinguished.

3, how to use mouthwash in the end?

The use of medical mouthwash should follow the doctor’s advice. Daily use of mouthwash packaging also generally has instructions for use. It is recommended that when you rinse your mouth, you can include mouthwash in your mouth and encourage your mouth to make effective contact with all parts of your mouth. This helps flush out small pits that remain in your teeth as much as possible. The food debris and soft dirt in the small furrows, tooth gaps, gums, lips and cheek furrows, etc., reduce the number of bacteria in the oral cavity, thereby achieving the purpose of cleaning the oral cavity. Daily mouthwash is recommended to be used twice a day. After brushing your teeth, use 20ml each time and rinse for 30 seconds. Do not rinse your mouth with clean water after you rinse.

Doctors recommend using mouthwash before brushing to ensure cleanliness. Of course, if you don’t brush your teeth at noon during work, it’s okay to use mouthwash only after meals.

So oh, kissing and exchanging 80 million oral bacteria can be fun, but you told me I can’t use mouthwash?
