Dentists will tell patients to floss at least once a day. Not following regularly can result in the growth of bacteria, which can lead to tooth erosion and loss of enamel. Floss reaches the sides of the tooth and underneath the gum line, which are places that a toothbrush can’t typically reach and clean effectively. It is important to get the right type of floss that is effective and comfortable for you. For example, if you have braces, you will need to get floss that is compatible with it. It is recommended that you floss after every meal or at least once a day at the end of the day.
