First, read the English article below.

In order to avoid future infections, it is essential to maintain good oral hygiene. The first step to good oral hygiene is to brush your teeth twice a day using a soft-bristled toothbrush. Hard-bristled toothbrushes are too harsh and can wear away delicate tooth enamel.  Hold your toothbrush at  45-degree angle to your gumline.   Brush your teeth using small circular motions, rather than brushing back and forth (as this can damage tooth enamel). You should brush your teeth twice a day, for at least two minutes at a time. Make sure to brush down to the gum line and don't forget the teeth at the back. Flossing is just as important as brushing, as it removes built-up plaque and bacteria from between the teeth that the toothbrush cannot reach. If this plaque isn't removed, it can lead to tooth decay, infection and gum disease. Floss at least once a day.  Hold the floss firmly between both hands and work it gently down between the teeth using a gentle back and forth movement. Try not to "ping" it down onto the gums, as this is irritating to the gums and can cause bleeding. Curve the floss into a “C” shape against one tooth. Slide the floss gently between your tooth and your gum. Holding the floss tightly, rub the tooth with gentle back and forth motions. Make sure to floss between every tooth and at the backs of your rear molar. You should always rinse your mouth after flossing to remove the dislodged plaque and bacteria. Using an antiseptic mouthwash helps to control the level of bacteria inside the mouth, while also keeping your breath nice and fresh. Look for one that has the ADA Seal of Acceptance; these have been approved by the American Dental Association as effective for your teeth.  You can use mouthwash before or after brushing. Pour a small cap-full of the mouthwash into your mouth and swish it between the teeth for approximately 30 seconds before spitting out. You can use a commercial brand antiseptic mouthwash, or simply rinse your mouth with undiluted chlorhexidine, which is available at most...
