Can you get the fake portion of a chipped tooth whitened to match your teeth?

Unfortunately dental bonding is not affected by teeth whitening. The existing dental bonding will need to be replaced to match the lighter color of your teeth following teeth whitening. 

You have what is called a bondig on your front tooth.  After whitening some times it does not match which it sounds like is what you have.  To fix this you would just need to have the bonding replaced with a lighter color.  Just rememeber that most whitening products need maintenance and without it the color will go back to the old color and the new bonding will once again stick out and be brighter than your tooth color.  Good luck
