Me too, but some people simply don't have even enough teeth to do it.
Apparently no natlang distinguish them phonemically.

And re: a point in your other post, yes [t_T] is a valid way of indicating a
dental affricate. Unless it contrasts with the cluster, you could also simply
write [tT] (or do it anyway and separate the cluster with a hyphen, like how
the X-SAMPA documentation suggests transscribing Polish 'cz' and 'trz' as [tS]
and [t-S]).

I guess if you wanted to be painfully exact, you'd need writing [t_d_T], but
that's beyond the dark as well as the pale.
