  We investigate the static solutions of Callan and Maldecena and Gibbons to
lowest order Dirac-Born-Infeld theory. Among them are charged wormhole
solutions connecting branes to anti-branes. It is seen that there are no such
solutions when the separation between the brane and anti-brane is smaller than
some minimum value. The minimum distance coincides with the energy minimum, and
depends monotonically on the charge. Making the charge sufficiently large, such
that the minimum separation is much bigger than $ \sqrt{\alpha '}$, may
suppress known quantum processes leading to decay of the brane-anti-brane
system. For this to be possible the zeroth order wormhole solutions should be
reasonable approximations of solutions in the full $D-$brane theory. With this
in mind we address the question of whether the zeroth order solutions are
stable under inclusion of higher order corrections to the Dirac-Born-Infeld
action.
