A tooth spacer has first and second tooth spacer body portions which each define at least one window therein. Extremely thin film, for example from about 0.0003 to about 0.0006 inch in thickness, is sandwiched between the tooth spacer body portions to form the tooth spacer. Portions of the gingival edge of the tooth spacer may be thinned to facilitate insertion of the tooth spacer between teeth.
