When a primary tooth is lost prematurely the teeth can drift
into the new space crowding out the permanent tooth that is
supposed to erupt into that space in the future. A space maintainer
keeps baby teeth from shifting into the space where the tooth
was lost so the permanent tooth can erupt in its natural proper
space. As the permanent tooth erupts, Dr. Gresla will remove the appliance. Space maintainers can help eliminate
the need for extensive orthodontics in the future.
