Whitening chipped teeth

Hi, my situation is that about 2 years I chipped my bottom two front teeth and I've left it until now. Now I'm thinking about getting teeth bonding to fill in the little chipped pits, but I want to whiten my teeth first so I won't have to worry about getting "technicolor teeth" later on down the line. My question is, is it safe to whiten teeth with hydrogen peroxide if you have two slightly chipped front teeth? The damage is small but the dentin may be exposed on one of the teeth (there was pain when it first happened but it went away after a few days and hasn't bothered me since), so would 3% concentration hydrogen peroxide damage the dentin at all if it was exposed?

Also I was reading about how composite filling falls out and stains after only a while, is that true? The chips are very small so I don't think I'd want to get a veneer or anything, but is this what I should be looking at instead? Is there a way you can test if the dentin is exposed and you need to get work done - or whether you can just leave it?

Thanks for your help.

Yes, composite fillings can fall off especially in the front teeth depending on the extent of the chip and your bite and how the teeth fit together.  I understand that you don't want to have multiple colored teeth.  I would recommend attempting to bleach your teeth and seeing if theres any sensitivity to it.  With a chip for that long, the pulp may have receded some and thus created a thicker layer to protect itself.  If the bleaching is too uncomfortable, I would recommend bleaching after getting a filling and attempt to guess the color.  If you find a nice dentist, he may redo it for free afterwards.  Just bring your concerns before getting the treatment done and see what he/she says.  

A veneer would still have the same issue with matching colors. If you bleached first, it'd be easier to match the color afterwards. Do note that bleaching isn't permanent either and your natural teeth would probably stain faster than your veneers.
