Most people brush 30-40% of the tooth surface after serious brushing, especially those who have unevenly arranged teeth, because the teeth are crowded and overlapping, it is difficult to brush the tooth surface of these teeth clean. If you can floss properly, you will make up for this deficiency. Flossing is a very ideal tool for cleaning teeth. Floss is mostly made of nylon, polyester or silk, and dental floss is generally coated with wax, some with aromatics and fluoride. 1. Will floss embedded in the gums damage the gums and why do my gums bleed every time I use it? Correct flossing will not damage the gums. Remember to “slide” the floss slowly into the gap between the teeth, close to the adjacent surface of one of the teeth, and embed it into the gums. From the lowest point of the gums, gently pull the floss up and down to clean, so as not to damage the gums, and the main reason for bleeding gums is inflammation of the gums, you should continue to floss and see a dentist for further treatment. 2.Will flossing make the gap bigger? The thickness of standard dental floss is less than 0.15mm, which is much smaller than the narrowest gap thickness, so it can easily enter the gap, so normally it will not make the gap bigger. 3. Does everyone need to floss? If you have conditions, especially if you have a gap, you should floss. If you have periodontal disease that causes gum recession and a large gap, you can choose to floss with a toothbrush instead. 4. Can I use toothpicks instead of flossing to clean the gaps? There are some people who first use toothpicks to pick out the food residue in the gaps between their teeth, but the surface of toothpicks is rough and does not meet the requirements of oral health care. When using them, it is easy to damage the gum tissues and cause gum bleeding by sticking the toothpick into the crevice. Over time, it is easy to cause gum recession and larger gaps. Therefore, the best way to clean the adjacent surfaces of your teeth is to use dental floss. Cut a piece of dental floss about 30-40 cm long and wrap the ends of the floss around the second knuckle of the index finger of both hands, about two or three turns. After scraping one side of the tooth surface, scrape the other side of the same tooth surface to clean the food residue, plaque and soft scale in the tooth surface. Change a section of clean dental floss, scrape the adjacent surfaces of the teeth one by one in the same way, and then rinse your mouth.
