How long does it take for a dead tooth to change colors?
do u mean when they turn yellow, if so, it actually depends on
how you treat them, i give my dog the dentix things every day, but
his teeth will get yellow so we have to pay to get them washed, but
i think if u dont give him the dentix, his teeth should turn yellow
quite fast.
u can buy tooth brushes for dogs at pet stores, that is if u
want to, but i strongly recommend that u at least use the dentix u
can get from asda, oh yea and they have special sizes for different
sized dogs.
