Abstract: A dental separator device for applying pressure against adjacent teeth to separate the teeth from one another so that a dental restoration can be made. The separator device increases the interproximal space between the adjacent teeth giving the dental clinician improved visibility and working space. The invention also encompasses a flexible matrix band used for making the restoration. The matrix band is wrapped around the tooth to define a desired mold or shape for the restoration.
