The most important method and means of dental care, brushing has become a part of people’s lives. In fact, it is a “homework” that we must do every day. If you do it well, it is naturally “good”, not only can remove bacterial plaque, remove residual substances on the surface of the teeth, so as to remove oral foreign matter and odor, but also can promote blood circulation and keratinization of the gums, and improve the resistance of the gums. However, if you do not pay attention to some small problems, you may only get a “failing grade”, so that the teeth are damaged, the gums bleed and recede. Brush your teeth? Ask the food first! In order to get “excellent” brushing, you must first find out when to brush your teeth. Some people think it’s best to brush their teeth right after eating for better dental health, but it’s not always the case. If you have just used starchy food, fatty food, sugar and other neutral food, or alkaline food such as alkaline water noodles, then naturally you can brush your teeth immediately to remove food residue and protect your teeth. But if you just ate a box of delicious strawberries, that’s a different story! Because the acidic food like strawberries contain oxalic acid, benzoic acid can make the tooth surface decalcification, reducing the hardness of the tooth surface, at this time immediately brush the teeth will cause damage to the tooth surface, and over time, will cause easy tooth allergy. By the same token, citrus juices, cold food containing vinegar is also acidic food, should not be brushed immediately after eating. It is extremely tedious to identify the acidity or alkalinity of food at all times. Therefore, some people suggest brushing your teeth two hours after eating. However, I think the best and easiest way is to rinse your mouth with water after eating, and brush your teeth in the morning and evening. This way you don’t have to mind when you eat and what you eat. Brush your teeth with the force of a rubber band. It is well known that it does not take much force to remove any substance from a smooth surface, such as dust on glass, which can be wiped away with a light wipe. The same goes for brushing your teeth. It only takes 150g of force to brush away the smooth surface of your teeth, which is equivalent to pulling a rubber band that ties your hair. And the best time to brush is 2-3 minutes. Too short, the cleaning effect is not enough; too long, over time, it is easy to hurt teeth and gums. However, the most important thing is to brush your teeth on all sides and leave no dead ends! Pay attention to these issues, the “homework” handed out, naturally, are “excellent” it! Choosing a toothbrush and brushing method should also be excellent The store shelves are full of toothbrush varieties, so the choice of toothbrush should also be excellent. It’s best to choose a toothbrush with moderately hard bristles, as too hard will damage your teeth and gums. Too soft may not clean your teeth. You can also choose to use an electric toothbrush or a sonic vibrating toothbrush. The latter is the same as an electric floor polisher when you use it, stopping at each part and letting the toothbrush rotate to clean that part. Don’t brush east and west to avoid missing some areas. The choice of toothpaste should also be excellent The choice of toothpaste should be targeted, generally no oral problems of people, the use of ordinary toothpaste, such as Colgate. If you have a problem, you should use the corresponding special toothpaste: if your gums bleed easily, you should choose the one with the function of stopping bleeding, such as double-sided needle toothpaste, Yunnan Baiyao toothpaste. If your teeth are allergic to hot and cold, you should choose anti-allergic ones, such as Comfort, Oravive. If your teeth are easy to decay, you should choose toothpaste with fluoride and calcium.
