Many people think that just brushing their teeth well is enough to maintain oral health. However, it is difficult to remove food debris stuck between teeth with just a toothbrush. Using dental floss is necessary to prevent periodontal disease and keep teeth healthy. However, improper use of dental floss can be harmful. Choosing floss that does not fit your gums and using excessive force can cause injuries to your gums and teeth. Learn the correct way to use dental floss.

Using dental floss can reduce periodontal disease by up to 78%

Food debris and tartar buildup between teeth can lead to cavities and various periodontal diseases. According to a study by Seoul National University, using dental floss can reduce periodontal disease by 30%, and using floss after each of the three daily meals can reduce periodontitis by 78%. The most ideal practice is to use dental floss after brushing your teeth following each of the three meals. If that is not practically feasible, flossing once before bed is also acceptable.

People with gaps between their teeth that trap food easily, those with gum disease, those with crooked teeth, and those with dental prosthetics or implants must develop the habit of using dental floss.

◇From choosing dental floss to usage instructions, what you need to know

Choose dental floss by considering the space between your teeth.

First, select dental floss that fits the space between your teeth. There are various types of floss, including thin floss and coated floss to make it thicker. For areas with wider gaps between teeth, apply the coating and use thicker floss.

Thin dental floss is better for areas with good spacing between teeth. Using thick floss in tight spaces can cause the gaps between teeth to widen, creating spaces where food can get stuck and increasing the risk of gum inflammation.

▷If you choose to use dental floss as if sawing with a gentle force, leave about 4cm of floss to use at once and hold it with your thumb and index finger. Insert it between the teeth and move both fingers back and forth as if sawing, allowing food debris to stick to the floss. Be careful not to apply too much force, as it can damage the gums. Also, floss the molars that are difficult to reach with your hands.
