어서 와~ 건강한 나! 9회 ; 입안은 매일 세균과 전쟁 중! 세균막 악순환의 고리를 끊자! You all have a war with bacteria in your mouth.

Hello, I'm a doctor who chases the truth, Dr. Park Mi-ra. Hello, I'm a doctor who chases the truth, Dr. Kim Young-shin. I heard you're going to teach me how to get rid of germs in my mouth. Isn't everyone brushing their teeth? Yes, everyone is brushing their teeth. Before I learned how to brush my teeth at the dentist, I thought, Who can't brush their teeth? Children learn how to brush their teeth at home. Have you ever wondered if you were really brushing your teeth? I brush my teeth every day. Yes, I think you're brushing your teeth. When you're young, you have fewer teeth, and you can see your mouth when you open your mouth a little. But when you get older, you have more teeth, and you can't see your mouth even if you open your mouth. Then it's hard to brush where you can't see. That's right. You can't see your back, you can't reach your hands, so you get help when you wash your back. I can reach everything. I can reach it, too. I don't need help, either. Wait, don't scrub, just get rid of germs in your mouth. I need a comparison. Your back is flat, so you can push it as much as you want. But teeth have different angles. The front, the back, and the molars are all different. Besides, I can't even see the molars at the bottom and the top. So I can't check with my eyes if the toothbrush is working properly. I can't see it, so I just brush it. That's right. I can't see it with my eyes. As I said last time, if germs and viruses are easy to get through, they will always come in. But getting through this is not a success at once. Then do you try several times? I'm still trying. Always. So you can come in under any conditions. Then what are the conditions? If there are too many germs, or if the immune system is too weak. If the immune system is normal, but there are too many germs, there may be a problem. If the immune system is normal, but the immune system is too weak, there may be a problem. Then if you try to prevent germs from coming in, the germs should be relatively less. Yes, relatively. So it's actually a war every day. It's a war. You're maintaining peace because you're protected by your immune system. I've never thought of it as a war. That's right. I'll tell you why it's a war to remove the bacterial membrane in your mouth. This is when my patient first tested the bacterial membrane in his mouth. All the red things you see here are bacteria. It looks thick and strong, right? It looks hard. Isn't that tartar? That's right. How long does it take for the bacterial membrane to become tartar? 24 hours. You have a really good memory. That's right. It's 24 hours. There's tartar on the bottom of the bacterial mass, on the teeth, and there's bacteria on top of it. After 24 hours, it becomes tartar again, and the bacteria and tartar are mixed. That's what the red thing is. You can think of it as a tactic similar to human tactics, in which bacteria become lumps and gradually increase their strength. So there's a lot of bacteria? There's a lot. But you can't just be affected. Then what should I do? In the Korean War, the People's Army of the Communist Party of China invaded Korea and occupied the south again. Do you remember what you did then? General McArthur split the People's Army in half to invade Incheon, right? That's right. It's the same way to remove the tartar on the mouth. The bacteria are very sticky and stick to the teeth, so they don't come off easily. If you keep cutting off that combination with a toothpick, the tartar weakens. The principle of the world is really the same. This is also a principle. That's right. The earth is spinning, the solar system is spinning, and the universe is spinning. Yes, I think so, too. It's really similar to the fact that you have to keep protecting yourself every day It's like removing the tartar on your mouth every day. It's like patrolling my body every day. That's a really appropriate expression. If you remove the tartar formed by the bacteria that come in every day, it looks like this. The red membrane looks thin. If you remove the tartar on your mouth once a day, the strength of the bacteria is greatly reduced. But can't you completely remove it? What should I do? You can't completely remove the bacteria, and you can't completely remove it. But it's time. I'll tell you how to remove the tartar on your mouth next time. Please wait a little longer. Goodbye, everyone. How can I hold it in? Hold it in. Thank you.
