Flossing can be beneficial to the health of the teeth and mouth, but many people are doing it wrong. Snapping or popping the floss between the teeth is highly discouraged by dental experts because it will damage the gums. Once the gums begin to recede from this type of harm, the sensitive root of the tooth can become exposed which can lead to more damage and pain in the mouth. Flossing and brushing should both be routine oral-hygiene practices, but doing both of them too much, or using the wrong technique, can have damaging effects on teeth. The best technique is to wrap a piece of floss around a tooth in a c-shape and ease it around the teeth to remove food and other damaging sugar or acid build-up.
