Teeth that
appear pink are teeth that have been traumatized, but not
necessarily broken. The pink color is due to bleeding in the pulp
chamber. With time, the color will change to purple and ultimately
to gray. These discolored teeth are a source of pain and infection
on a daily basis. When bleeding occurs inside a tooth, the hard
tissues of the tooth do not allow the injured pulp any relief from
the pressure and swelling. The end result of this process is that
the pulp dies. The dead pulp provides a safe haven for bacteria
that regularly enter the bloodstream. As with broken teeth, an
abscess will develop at the root tip. Discolored teeth should
always be evaluated and x-rayed to determine if the tooth must be
extracted or, hopefully, salvaged by performing a root canal
procedure.
