Oral-B SuperFloss is ideal for cleaning braces, bridges and wide gaps between teeth. Its three unique components; a stiffened end, spongy floss and regular floss, all work together to help you achieve optimal oral hygiene. The stiffened end allows for easy flossing under dental appliances, while the spongy floss effectively cleans around braces and in wide spaces. The regular floss is designed to remove plaque from beneath the gumline. Each pack contains 50 strands.
