Space retainer

Space retainers are appliances used in the mouth to preserve and maintain space. They are necessary when one and more primarily molars have been prematurely lost due to trauma or disease. Using a space retainer allows the permanent teeth to erupt, or grow, into the correct alignment with proper tooth to tooth contact.

When properly used, speace retainers can prevent movement of the first molars, preventing loss of space for other teeth, including adult bicuspid and cannies, which are permanent.
