It is after a complete oral examination that the hygienist proceeds with scaling (tartar removal). The cleaning is done using a small metal curette designed for this purpose. Once the tartar is removed, the hygienist usually follows up with polishing to remove visible stains on the tooth surface. To do this, a gritty paste is added to the rotating electric brush. Furthermore, to ensure that all interdental areas have been thoroughly cleaned, the hygienist finishes the session with dental floss.
