After an injury, color changes to a tooth may occur rapidly or take
several weeks to develop. A tooth may change color soon after an injury and
later return to its normal color.
A baby tooth (primary tooth) that turns yellow usually does not
require treatment. It may mean hardening in the inner core of the tooth (pulpal
calcification) has occurred.
A gray, black, or pink color to a tooth may indicate bleeding inside
the tooth. Further evaluation by your health professional is needed.
After evaluation, treatment of a discolored tooth might include
removal of the tooth (extraction), a
root canal, or simply watching the tooth for a
while.
