Toothbrushes do not clean between your teeth. interdental floss is needed because it does clean between your teeth. If you do not floss everyday, you will get cavities between your teeth. Once a day is enough, and once it becomes a habit, it can be done in less than 1 minute.
Some people claim that certain toothbrushes or waterpik systems can do what floss does, but if you can buy a roll of floss for $1 at any drug store, and it takes less than a minute to do, how much cheaper and easier can it get?
DENTAL FLOSS HOLDERS:
These can be used to help get to the hard to reach areas in the posterior of your mouth, or many parents use them to floss their children who have smaller mouths.
DENTAL FLOSS THREADERS:
Dental floss threaders are rigid pieces of floss that have a loop and an extention (looks like a hollow lollypop) and functions just like an enlarged needle. You thread regular dental floss through the ring/eye, then send the extention underneath tooth bridges or braces . Below are illustrations of both.
SUPERFLOSS and DENTOTAPE:
Superfloss is floss with an extremely thick center, almost like thin yarn. This is used when you have large spaces between your teeth or can be used with dental floss threaders as noted above.
Dentotape is thicker than regular floss, but not as thick as superfloss. It can be used instead of regular floss, or in conjunction with, depending on what types of restorations you have in your mouth.
