Roeko Parotisroll works especially well to hold saliva from the parotid gland back, but naturally works well in any oral space to provide a dry area. These dental rolls provide more working space buccally, lingually, or labially. When used buccally, there is gental pressure on the parotis from the roll, while it retracts the cheek to keep the mouth open. Lingually, the arch shape of the roll holds down the tongue. Labially, the lip can be retracted using Parotisrolls for cosmetic densitry, orthodontics, and when treating children.
