Abstract: A dental floss holder for securely fastening one end of a dental floss instead of winding it around a finger includes a pair of jaws, two mating surfaces, and a locking member. The dental floss is retained between the jaws. One of the mating surfaces is formed on one jaw and the other mating surface on the other jaw. The locking member locks the jaws tightly such that there is substantially no gap or space between the mating surfaces so that the mating surfaces abut against each other closely to fasten the dental floss. The locking member and the jaws also comprise mating surfaces to be able to securely fasten the dental floss when the locking member locks both jaws.

Abstract: A dental floss holder for securely fastening one end of a dental floss instead of winding it around a finger includes a first member, two mating surfaces, and a connector member. The dental floss is retained on the first member. One of the mating surfaces is formed on the first member and the other mating surface on the connector member. The connector member connects with first member so as to abut the mating surfaces closely against each other to fasten the dental floss.
