The shapes of dental floss mainly include flat dental floss and round dental floss.
Flat dental floss: Flat dental floss is flat, thinner and softer. This type of dental floss can be inserted into the gaps between teeth more smoothly, and is suitable for people with thinner teeth. Because of its large contact area, it has a better cleaning effect and is suitable for daily use.
Round dental floss: Round dental floss has thicker lines and harder materials. This type of dental floss is suitable for people with wider gaps between teeth, because it has a wide contact surface and a relatively large volume, which can better clean wide gaps between teeth.
In addition, dental floss also has different materials and designs, such as waxed dental floss, unwaxed dental floss, and expanded dental floss. The surface of waxed dental floss is coated with wax and is relatively smooth, which is suitable for novices or people with thinner teeth; unwaxed dental floss has greater friction and better cleaning effect, which is suitable for people with wider teeth. Expanded dental floss will expand when it comes into contact with water, increasing the contact surface with the teeth, and is suitable for people with normal or wide gaps between teeth.
