Good observation. I've had patients that are so obsessed with white teeth that they scrub them to death. When the enamel gets thinner the tooth takes on more of the shade of the dentin layer which is usually yellowish.

I recommend soft bristles but a lot of the wear can be due to technique. Fine grit sand paper can do the same job as coarse grit, it just takes more effort.
