Nylon floss is made up of several strands of nylon material, meaning that it can shred, tear, or snag between the teeth if it gets caught on sharp teeth. Even though the single filament floss is more expensive than nylon, it will slide easily between teeth, even tight areas and spaces. Unlike nylon, single filament is impossible to shred or tear.

Abscesses are very serious conditions, and can lead to serious matters if they aren t treated immediately.

This bacteria will eventually spread from the root of the dead tooth into the tissue that is below and create a pocket of pus - the abscess. Fractures or cracks occur with all ages, although they are more present in those above the age of 25. They can be very painful, hard to diagnose, yet sometimes easy to treat.
