Hello, I'm glad to answer your questions. First of all, if gum bleeding means that you have gingivitis now, the main cause of gum bleeding is dental calculus, that is, because brushing your teeth is not in place at ordinary times and the food between your teeth is not cleaned up. In this case, dental calculus may appear under your gums, resulting in natural redness and swelling of your gums. So it is easy to bleed gums, especially brushing your teeth or biting apples.
The treatment method is very simple, that is, just wash the teeth. After the impurities between the teeth are removed, the gums slowly recover. At the same time, use some mouthwashes normally, such as mouthwashes that can be bought in the supermarket or other mouthwashes that can be bought, and clean them up after each meal. Brush your teeth well. It is generally recommended that you brush your teeth once a year.
