Many patients ask this. They know that they will not be able to floss a bridge the same way that they can individual teeth. Fixed bridges have solder connections that make it impossible to use floss regularly, but they do need to be kept clean. Floss threaders, stimudents and interproximal brushes are the tools of choice to help clean between bridged teeth. Similarly bridges need to be cleaned regularly at the dentist. They have margins that can collect plaque and should be professionally cleaned with regularly scheduled cleanings. I have written a short article on this top on my N.Y.C.
