How many times a day do I brush my teeth and how do I brush them? You may think this is a “retarded” question because we have been taught by our parents since we were young that we should brush twice a day, once in the morning and once at night. But have you ever thought about why we brush our teeth twice a day instead of three or four times? Have you ever thought about the purpose of brushing your teeth? If you have determined the purpose of brushing your teeth, you may have doubts about brushing twice a day. First of all, we brush our teeth to remove food debris from our teeth because the bacteria in our mouth will attach to the surface of our teeth and they will break down the food to produce acid and destroy the surface of our teeth, which is commonly known as “tooth decay”. Most of the teeth are made up of calcium, which will become soft and flaky under the action of acid. There is a time limit for bacteria to break down food, usually 12 hours, so most people think that brushing twice a day is enough. But we have to calculate our habits, we like to brush our teeth in the morning before eating, otherwise there is a taste in the mouth, eat a good breakfast, then brush your teeth before going to bed, morning and evening brushing time has been more than 12 hours, that is to say, teeth have been eroded, and the original morning time if you can brush after breakfast, then we can also understand that until lunch time will not have food into the mouth. However, the habit of brushing twice a day is not good enough to remove food debris. Therefore, if conditions allow, we recommend that you can brush your teeth after each meal, or at least rinse your mouth, and brush your teeth does not necessarily have to use toothpaste. Here we will talk about how to brush? Most of the patients who visit the clinic because their teeth are sore from drinking cold water or inhaling cold air are suffering from wedge-shaped defects caused by brushing horizontally or using a large, hard-bristled toothbrush, i.e., cervical strips or wedge-shaped defects, which can cause tooth inflammation in severe cases. So I hope you can change the way you brush your teeth after reading this article. When choosing a toothbrush, you can try to choose a brush with a smaller head to facilitate the movement in the mouth, so that you can brush every tooth, preferably to the last side of the last tooth; in addition, you should try to choose medium or soft bristles to avoid damaging the tooth structure and flesh. The most important thing to pay attention to is the method of brushing, which is also the direct cause of cervical wedge-shaped defect of teeth. There are generally three ways to place and stroke the toothbrush when brushing. 1, vertical brush, teeth bite after we can see the outside of this circle are so brush, rather than pull saw-like horizontal brush, as shown in the picture is the first toothbrush oblique paste in the neck of the teeth, that is, we can see the teeth and tooth flesh intersection, and then the upper teeth down brush, and vice versa, the lower teeth up brush. This also avoids the above mentioned wedge-shaped defect in the neck of the tooth. 2, vertical brush, you have to ask, why still say vertical brush, in fact, this vertical brush depends on whether you adapt. If you open your mouth, you can also use the vertical brushing method more conveniently on the inside as opposed to the outside of your teeth, and that is the best. However, some people say that it is difficult to brush vertically inside, so I will tell you another way to brush vertically. Come on, let’s try it together, put the toothbrush handle up, just like the little baby in the picture, let the long axis of the toothbrush head and teeth vertical, then use the head of the toothbrush several rows of bristles to complete the cleaning of the inner side of the teeth, but also to vertical brush posture. 3, horizontal brush, this is the common way, some friends will only use this position, that will have damage to the teeth, in fact, we only use the horizontal brush in the teeth biting surface, as shown in the picture, that is, we chew food when grinding each other surface, because of this high efficiency, removal efforts. 4, Finally, you can choose to brush the tongue, or not brush. In addition, some people will be more tangled, in case you accidentally brush the vertical place and use the horizontal brush how to do? You should not worry too much about this, because the tooth structure is still relatively strong, a small amount of incorrect brushing will not have much effect. Another thing to emphasize is the brushing time. If you brush every tooth on every side, you should at least make sure that you have at least 3 minutes. To give you a summary of a jingle – vertical vertical horizontal, brush teeth!!! Second, the use of dental floss dental floss should be a necessity for oral cleaning, and toothbrushes should be partners, good cooperation to make our mouth clean more clean. The role of the toothbrush is on the big side, that is, we can usually see the surface, and you think about it, the teeth have a total of how many sides? For example, two teeth adjacent to each other, you generally can not see in the mouth, only when you eat something embedded teeth will find its existence. In fact, flossing is what we call the gap, but it is important to note that flossing is not only for picking out the stuffed teeth, but more importantly for cleaning the teeth. In other words, we must floss close to the side of the teeth to pull inside and outside to scrape off the food residue attached to the teeth and reduce tooth decay caused by food blockage. There are two types of dental floss in the market, you can choose according to your needs.
