Great question! Depending on the design of your dental bridge, you have several options. You can use regular string floss with the help of floss threaders to "thread" the floss under the false tooth (also known as the dental pontic). Once the floss is under the bridge, you can pull it to one side and hug, up and down your tooth. Leaving the floss under the pontic, slide over to the other side and hug against the tooth on the other side, going up and down to remove any plaque and bacteria. You also have the option to use proxabrushes, that are like little pipe cleaners or Christmas tree bristles on a handle to go under the pontic tooth, and similar to the floss, scrub against the tooth on either side of the bridge. Another option is a water or air flosser. Using a water or air flosser is oftentimes easier to use for patients, and works by concentrating a stream of water or air under the bridge. They don't work quite as well as floss or proxabrushes in removing stuck-on plaque, but can be a helpful adjunct to normal brushing and flossing.
