Prophy paste is a type of dental paste containing mild abrasives. It is used for polishing teeth and removing plaque, calculus and staining. It is also used to prevent future dental caries. Prophy paste is short for prophylaxis paste. Prophylaxis is the term used to describe treatment given or action taken to prevent disease. Professional tooth polishing with prophy paste is carried out by a dental hygienist or general dentist, typically at the end of a scale and polish appointment.
Prophy paste traditionally comes in single-use cups or multi-dose tubs or tubes. The paste is applied to a rubber cup attached to a dental handpiece called a prophy angle. The cup is then rotated at slow speed as the paste is spread over the crown of the tooth to remove surface plaque and stains. Screw-in prophy brushes are often preferred when polishing and cleaning children’s teeth.
An alternative material used to achieve similar outcomes to prophy paste is air polishing power. This is applied with the use of an air polishing unit.
Prophy pastes are made up of a mixture of binders, humectant, colouring agents, preservatives, fluoride, flavourings and abrasive material. Either chalk, also called whiting or calcium carbonate, or pumice is used as the abrasive in most dental prophy pastes.
Prophy pastes are categorised primarily by their abrasive grades. These are course, medium and fine.
Fine prophy paste has a smoother feel to coarse prophy paste which has a grittier texture. Fine paste or a mixture of fine and medium paste is often preferred for children.
