My veneers are too white now and stick out terribly. (Photo)

Veneers should look natural, not like fake teeth.  The color, shade and contour should match precisely.  I would definitely give your dentist an opportunity correct the two veneers that were placed, but I would not recommend doing additional teeth with the same dentist, until your front two teeth are to your liking.   Good luck and I hope this helps.

I would first attempt to whiten your other upper teeth and see if that helps. If not, you would need to replace the veneers with new ones.  If so, I would recommend doing at least four and make sure that they are Emax veneers and not Lumineers.  In my opinion, Emax is a far superior material from a functional, strength, and aesthetic standpoint.  Good luck.

You can bleach you other teeth to get a better shade match but it looks like the problem is also related to shape and size relations to other teeth.  The best results are always 4 anterior veneers or 8-10 veneers.  Six veneers usually look fake especially if large color change due to the curve of the mouth at the canines.D Ira L ShapiraThinkBetterLife.com
