I have three teeth that were bonded and have darkened. How can I get them white again?

The only option for whitening a darkened bonding is to replace it. Composite bonding materials absorb stains and can darken over time. They will require replacement in highly visible areas of the month as they darken. Some of the newer composite materials stain less than the previous generation of composites.
