Before waking up in the morning and going to bed at night, the upper and lower teeth of the teeth can collide with each other, and the number of collisions and the impact force can be increased from ten to fifty times daily, which can make the teeth stronger. Rinse your mouth with water after every meal, close your mouth, let the water flow back and forth in your mouth, let the food residue in every corner of your teeth be washed away, and then spit out the water, so that you can flush both sides almost! There is no residue in the gap between teeth, which reduces the formation of bacteria.
Wash your thumb and forefinger with water, massage your gums back and forth with clean fingers, or massage with special tools. Massage for a few minutes like this can promote blood circulation in the gums. Healthy gums make teeth stronger and prevent teeth from loosening and falling off due to premature gingival atrophy. Keep your mouth closed, and then keep pressing the upper wall of your mouth with your tongue, which can promote a lot of saliva secretion. There are a lot of immunoglobulin and lysozyme in saliva, which can increase immunity. They can kill bacteria in the mouth and protect teeth after a long time.
Toothbrushes are not suitable for use for a long time, because some dirt bacteria will remain during brushing. If it is not changed for a long time, these dirty bacteria will return to our bodies. The strength used in the process of brushing teeth is also very particular. If the brush is too light, it will have no effect. If the brush is too heavy, it will affect the normal development of teeth and even the firmness of gum roots. Therefore, the intensity used in the process of brushing teeth should not be too light or too heavy, just right.
