I am a big fan of whitening. It is conservative and very effective as long as your teeth have enough enamel. The yellow part showing through is most likely the dentin and whitening is intended to work on the enamel portion.
For patients who have lost enamel to the degree that you are describing, then a restorative option becomes the best choice. That includes veneers, if there is enough enamel to achieve good bonding, but may mean full coverage all ceramic crowns for the best long term solution.
Remember that you are not only looking to improve the way you look, but you need to restore your function today and for your future.
