18년차 치과의사가 깨달은 것. 양치할 때 제 아이들에겐 '이것부터' 알려줄 겁니다. (최세경 원장 1부)

50% of tooth decay is from brushing your teeth. Many people brush their teeth like this. This is the most wrong thing. No matter how much you brush your teeth, it doesn't work. There are people who come to our hospital often, but those who have been healthy for the rest of their lives have a really rapid tooth decay. It's really good if you invest just 5 minutes. If you didn't do it during the day, it's okay. If you didn't do it in the morning, it's okay. The important thing is I'm Dr. Choi Se-kyung, an orthopedic surgeon. I've been a dentist for 18 years now, and it's been over 10 years since I opened it. What is the most important thing in dentistry? It's brushing your teeth. I'll give you all the knowledge I have today about brushing your teeth. I think Koreans judge whether their teeth are well-brushed by two things. First of all, when you brush your teeth, you look in the mirror and see if it's shiny. And when you brush your teeth with your tongue, you can see if it's smooth. If these two things go well, you think, Oh, I brushed my teeth well. The most important thing is not the part where the tongue touches, but the part where the tongue doesn't touch. It's very important to wipe it well. You have to keep that in mind. In my opinion, 50% of tooth decay is caused by brushing your teeth. If you brush your teeth well, it's not 100%, but 90% of tooth decay can be prevented. First of all, when choosing a toothbrush, there are two things to consider. The type of toothbrush, and the size of the toothbrush head. When you get older, when you're in your 30s, you feel the gap between your teeth and your gums, and your gums get swollen. But if you scratch it with a hard one, it'll come off easily, but your gums will get hurt, and your gums can go down again. At that time, it's better to use soft toothbrushes like fine hair. Next, the size. There are big and small toothbrush heads. If it's big, it's easy to use. You have to wipe it several times at once. You have to wipe it and go out. The best thing is, the smaller it is, the better. The smaller it is, you can wipe every corner. The problem is, if it's small, what's uncomfortable? You have to go out quickly, but if you wipe it for 10 minutes, you'll get upset, and Koreans like to do it quickly. If it doesn't work, it's important to wipe every corner with a small toothbrush before going to bed. I need to tell you about the ingredients that make up the toothpaste first. There are more abrasives than you think. You have to choose the right combination according to your gum disease, tartar, and syringe symptoms. Actually, it's really hard to figure it out. So what we think is the most important thing is that there aren't too many artificial ingredients, and that the amount of abrasives is just right. It's more important to adjust the concentration of abrasives to suit your taste than to make it too chemical or to make it too sticky because there are too many surfactants. If you flip the toothpaste over, there's an abrasive on the label. If you don't have a big problem, and you go to the dentist and there's a little bit of abrasive, but it's okay. Then you can use a normal abrasive concentration of 1,000ppm. If you have a lot of abrasives, I recommend using 1,500ppm. When you're young and you swallow a little toothpaste, it's better to use about 500ppm. You know the chewing side? The chewing side doesn't really matter. What you're wiping wrong is the side that meets the teeth and gums on the outside or inside. How do you usually wipe these sides? There are a lot of people who wipe it like this. This is the worst. If you wipe it sideways like this, the things in the gap don't come out at all. Secondly, there are a lot of people who know that it's wrong to wipe sideways. Those people just sweep up and down and wipe it. That's when the outside side is wiped well, but the side between the teeth and gums is not wiped. But the most important thing for us is that the outside side is wiped roughly. The most important thing is the gap between the teeth and gums. If you want to wipe this gap properly, you don't just use it, but you put it between the teeth and gums at 45 degrees and sweep it up. It's very important to wipe it like this. It's the same inside. Sweep up the inside at 45 degrees. The most difficult thing for me when I use a regular toothbrush is this back part. Can't I just wipe it like this? Because of the shape of the mouth, I have to put it in like this and wipe it, but this part was a little difficult. If this part can be erected like this, sweep up this side at 45 degrees. It's not easy. That's right. If we live busy, we have no choice but to follow this principle. But there's one thing you can't compromise on. That's brushing your teeth before you go to bed. While you're sleeping, your ID card gets smaller, and your tongue gets weaker, so the bacteria in your oral cavity suddenly reproduce. So I think most oral cavity diseases occur while you're sleeping. Especially, if you sleep with your nose and mouth wide open, your saliva is very dry. There are people who come to our hospital often, but when they get older, they get dry mouth syndrome. Those who have been healthy for the rest of their lives really quickly ruin their teeth. Those people, especially if they don't brush their teeth well, bad bacteria reproduce and break down. So it's really good to invest just 5 minutes before going to bed. If you didn't do it during the day, it's okay. If you didn't do it in the morning, it's okay. 5 minutes before going to bed. It takes 2-3 minutes to brush your teeth properly. What do the other 2-3 minutes do? Young people use dental floss. People who are a little older use dental floss. What's the difference between dental floss and dental floss? It's a big difference. People with lower gums and more space can use dental floss, but it's too inefficient. That's when you use dental floss. Young people usually have more space. That's when you use dental floss. I've been using electric toothbrushes for almost 10 years. When many people brush their teeth with an electric toothbrush, they think it will ruin their gums. They think they can't do it better than their hands because they're so nervous. If you know how to use it properly and use it, it's more effective than a regular toothbrush. And there are a lot of cases where you can't focus when you brush your teeth. You're watching Knowledge Insider while brushing your teeth, right? If you just hold it like this, you can't brush your teeth. Electric toothbrushes are much better because you can just hold it like this. Especially if you're not used to it, There's a study that says it's much more effective to get rid of plaque. A lot of patients ask me, How about using an electric toothbrush? Then I tell them it's good. Instead, I tell them to choose the mode well. The biggest thing about electric toothbrushes is that if you put it in a certain area, it automatically cleans it. When we go to the car wash and go into the car wash, the car doesn't wipe while moving. Like that, you have to put it in one by one. For the sake of understanding of Knowledge Insider subscribers, there's a very famous company in Oral-B. There's a new electric toothbrush called IOTEN. I'm going to use that toothbrush to demonstrate. The biggest mistake when using an electric toothbrush is to turn it on. Wiping like this, rubbing like this, You can't see the effect at all. It can only hurt your gums. Just like a regular toothbrush, you can put it at 45 degrees. All you have to do is stay there. If you leave it at a 45-degree angle for 3 to 5 seconds, This part will clean itself. Then you don't move right next to it. Take it off a little bit, move it again, and leave it at a 45-degree angle. It takes about 40 seconds from here to the side. Wipe the outside for about 40 seconds. When patients come to the dentist, they brush their teeth three times a day. They say, Why is it rotting? Why is this body broken? The important thing is that the part where the tongue doesn't reach. I told you it's an invisible part. But there are a lot of cases where you miss it. I don't think it matters if I move a little bit faster. It's wiping a little faster, so I'll move it and wipe it. You know the back side? The part that doesn't wipe well. This circular head is very adhesive. If it's been three seconds, it'll be wiped very well. I'm done scanning at the dentist. At the end of the day, I'm going to clean it up. I know it's made by looking at the shape. And the toothbrush doesn't just vibrate together. It's a magnetic system. It vibrates differently one by one. So what I feel is that it's not just a little ignorant. Each one of them vibrates differently. It's a little more adhesive. I think the plug removal is going well. The most important thing is not to play too much. At first, I did it too hard, and it hurt a little. I'm getting a little bit of a good feeling. The electric toothbrushes that come out these days. He calculated the appropriate pressure and told me. If you turn on the electric toothbrush, you'll get this basic light. If we give it the right amount of force, You'll get a green light. This is the right amount of force. The thing you have to avoid the most. The red light comes out like this. I can see that you're putting a lot of effort into it. If you give it a lot of force like this, It could taste refreshing. You can get gum removal. Personally, I think this is a good job. In the past, I only charged the charger. If you put a lot of effort into it, the color of the charger. It's okay when it's appropriate. If you put a lot of effort into it, it turns red. Another important thing is that time comes out like this. And the person who's doing it in a strange way recognizes it. That part is shiny. When you're done with that part, the color is like this. What part did you finish? That's how it comes out. So there are three places on the lower jaw and three places on the upper jaw. 20 seconds, 20 seconds, 20 seconds. It's set up to finish brushing your teeth for two minutes. I think it's quite useful. I can't say it's a disadvantage of electric toothbrushes. But I can't brush my teeth in a hurry. I have to do it one by one. If I have to go out in a minute, I just wash my face and go out. But actually, if we're going to brush our teeth properly, I didn't wash it quickly. You have to wipe all the parts. All the patients who come to the dentist have a different pattern. Especially, there are people who have a lot of cavities. There are people with weak gums. There are people who correct their gums. There are people who have a lot of cavities. There are people who have to wipe it well in between. It's good to choose a toothbrush according to that condition. Actually, it's not that easy to choose. There are four toothbrushes here. The basic form is called the ultimate clean toothbrush. It's made at a 16-degree angle. It's the most effective way to remove plaque. If you're just worried, You can use the basic ultimate clean toothbrush. I have very weak gums here. If you touch it a little bit, it'll bleed. There's a gentle care toothbrush for those of you who have weak gums. It's made up of 4,000 ultra-fine hairs. It's a little softer. It's very soft when you touch it. And then I think I've developed this toothbrush very well. It's called the targeted clean toothbrush. I think it came out to make a clean target. It's actually very difficult for people who correct their gums to use traditional toothbrushes. There are a lot of devices and wires. I can't brush my teeth. Every time I come, I always say, Please brush your teeth well. I'm begging you. If you put it around the correction device like this, If there's a big toothbrush around the device, I can't get in here. It's very clean around the device. I think it's pretty good. So, if you have a lot of braces or braces, I think it would be good for people with a lot of gaps to use it like this. As a dentist, I'd like to summarize the advantages of electric toothbrushes. First of all, it's better than a real hand. I'm going to focus on brushing my teeth. I'm going to brush my teeth clean and sleep happily today. I don't think so. There are a lot of times when I unconsciously brush my teeth. There are a lot of times when I miss the parts that I can't see and the parts that I can't touch with my tongue. But there's a part that I don't brush, and there's a part that I miss. I wanted you to know that. So I made an app and marked it. So I'm going to show you which parts I'm brushing. I've done it before, and it's amazing. If I'm brushing here, it's floating here. And I'm brushing this part. It also checks the time. Toothbrush replacement How do I brush the wrong part? It's all coming out. I think it's a good reference.
