Microbrushes are used for applying dental materials directly onto teeth and restorations. These small brushes are ideal for accessing difficult to reach intraoral areas, as well as small areas where anything from adhesives and primers, to varnishes and whitening gels need to be applied. Microbrushes are generally disposable and often feature plastic handles. While some materials include brushes with their packaging, having an extra supply around the practice is always a good idea.
