Loss of the primary (also known as deciduous) teeth before the usual age.
Comment:
The primary teeth are usually shed and replaced by the permanent teeth, usually by the age of six years. With premature loss of primary teeth, there is a delay between the loss of the primary teeth and the eruption of the permanent teeth.
