General Kashrus Policy on:

Dental Floss

Back to Policies

The fibers and wax used in dental floss are made of innocuous ingredients and do not require kosher certification. However, many varieties are "flavored", and flavors are kosher-sensitive. Accordingly, for Pesach one should only use unflavored dental floss, and for year-round the unflavored variety is preferable.
