# Tight Teeth Floss > Tight contacts can shred or trap floss. Learn the sawing motion, softer products and when to ask a dentist about a rough edge. ## Guides - [Why Floss Shreds](https://flossing-tight-teeth.pages.dev/floss-shredding-causes/): Floss usually shreds because it is catching on something: a very tight contact, a rough edge on a tooth or filling, or too much force when pushing it through. - [Ribbon Floss for Tight Contacts](https://flossing-tight-teeth.pages.dev/ribbon-floss-for-tight-contacts/): Ribbon floss is a flat, wider thread that some people find easier to slide through snug gaps and gentler on the gums than thin string. - [Rough Edges and Restorations](https://flossing-tight-teeth.pages.dev/dentist-check-rough-edge/): If floss catches, shreds or snags in one spot, the cause may be a rough tooth edge or an uneven filling or crown. - [Floss Threaders Explained](https://flossing-tight-teeth.pages.dev/floss-threaders/): A floss threader is a small, stiff loop that pulls floss under a bridge, a brace wire or a fixed retainer, where ordinary floss cannot be pushed through. - [The Gentle Sawing Motion](https://flossing-tight-teeth.pages.dev/sawing-motion-gentle/): The gentle sawing motion means easing floss through a tight contact with tiny back-and-forth movements instead of pressing straight down. ## About - [About Tight Teeth Floss](https://flossing-tight-teeth.pages.dev/about/): not medical advice, how the site is funded and how guides are made ## Optional - [RSS feed](https://flossing-tight-teeth.pages.dev/feed.xml)
