Why do Americans attach great importance to teeth? Do teeth really need such care?

With regard to tooth protection, dental caries must be filled, otherwise it will get bigger and bigger. Bad breath must have a reason. Many people may not have bad breath, but many people in China have mild bad breath. Mild halitosis is usually caused by chronic inflammation. Brushing your teeth every day can't be eliminated, so you need to go to the stomatology department for cleaning. Gum bleeding is generally a manifestation of inflammation. For example, it is easy to bleed when brushing your teeth. Some people may think that their gums are prone to bleeding, but this is probably just caused by inflammation. Pay attention to oral hygiene after inflammation is eliminated. Besides daily brushing, I think gargling is very important, especially after meals. After eating sweet or sour food, gargling plays a great role. For example, after drinking cola or coffee, gargling is strongly recommended. Then there is dental floss. Try flossing. Flossing will make you comfortable. Floss can remove the residue between teeth, so can toothpicks, but toothpicks may increase the gap for a long time if they are not very soft. There are also sprinklers or air cleaners, which can also play the role of dental floss. Besides, I see many people brush their teeth 5-6 times a day. I don't think too much is good. Toothpaste has friction particles, especially some toothpastes marked with whitening function. Too much brushing will actually damage the enamel on the tooth surface.
