once the shell of the Tooth has given way to the cavity, the

the disease spreads thus rapidly over the cavity, as soon as
the Tooth has given way, does not depend simply on the
exposure ; for if a sound Tooth be broken by accident, so as
to expose the cavity, no such quick decay ensues : however,
sometimes we find in those cases, that exposure of the cavity
will produce a decay, and even pain, similar to an original

posure to external injury, its cavity will not nearly so soon
