Options for whitening bonded teeth?

Using whitening agents on your teeth can brighten your smile but it will not change the shading of your bonding. The only way to change the color of bonding is to replace it after completing whitening. Tooth bonding is certainly quicker and less expensive than porcelain veneers.  Veneers, though more expensive and time consuming, will have more color stability and deliver a much more desirable cosmetic result.

Rebonding is certainly an easy and inexpensive procedure to update your look.  You will want to whiten your teeth prior to having the bonding performed so they can match to your new shade.  If you you desire a more permanent fix that will not have the staining issues of the binding then you could get an estimate on porcelain veneers or porcelain crowns.  This will be more costly and non-reversible, make sure you are okay committing to this treatment option. 

Whitening
won’t change the color of composite bonding. The only way to change the color
of bonding is to replace it, which can certainly be done. The advantages of
bonding are that it can be done more quickly and less expensively than
porcelain veneers and it can be repaired in the mouth. Porcelain veneers are
more expensive and time consuming to do, but will be more color stable over
time. Keep in mind that veneers will also need replacement eventually and if
you’re young enough, more than once.

Rebonding is certainly a viable option. Ceramic veneers are quite a bit more expensive, but the color will not degrade over time.  If finances are not an issue, go for the veneers.
