Primate canines are apparently primarily for male-male sexual dominance
displays. The size of canines in primate is very closely correlated with
how often males fight for females. Monogamous species have small canines
and harem species have big ones.
But, yes, many primates eat mostly fruit, including some putative ancestors,
and I think it is reflected in the teeth somehow.
