Toothbrush The focus area for brushing should be the junction of the teeth and gums and inside the gaps of the teeth. To ensure that this area can be brushed, the bristles should be at an angle of 45 degrees to the tooth surface. When moving the toothbrush, you should not pull it horizontally, but shake it in place and brush it vertically after a few times, gently. It is not the case that the harder you brush, the cleaner it is. When brushing the lingual side of the front teeth, you can hold the toothbrush up and move it up and down. Toothpick The purpose of the toothpick is to scrape away the bacteria adhering to the adjacent surfaces of the teeth. A qualified toothpick should have a smooth surface and be oval or triangular in cross-section. The habit of randomly grabbing matchsticks, bobby pins, sutures, etc. to pick teeth is harmful. Floss Regular sewing thread is not a substitute for special floss. Take a piece of floss about half a foot long and knot the two ends together in a loop. Put your middle finger, ring finger and little finger inside the ring, hold the floss and pick up the floss with your thumb and index finger with a distance of about 50 px. Pull the floss tightly and gently press it into the teeth with a sawing motion. When the floss reaches the edge of the gums, make a letter C shape and slowly slide it between the teeth and gums until it meets resistance. Move the floss up and down to scrape the bacteria from the tooth surface. Repeat to scrape the bacteria from the adjacent surfaces of each tooth, especially the distal mesial surface of the last tooth. Gap brush (interdental brush) Designed to remove bacteria from between teeth. Easier to access the smallest gaps. Commonly used to remove bacteria from interdental spaces, root divisions, around orthodontic braces, etc.
