This is the dental floss I have been using for 7 years.

Hello. I have been consistently using dental floss since I developed a cavity between my teeth. No matter how hard I brush, the spaces between my teeth cannot be cleaned with a toothbrush.

Oral-B is famous for dental floss, and I have also been using Oral-B floss for 7 years. I use the wax version over the mint one, and I am satisfied with it.
