Oral compositions such as toothpastes, toothpowders, liquid dentifrices, mouthwashes, denture cleansers, chewing gums, candies and the like are described. The oral compositions have enhanced antiplaque activity together with excellent cleansing performance, physical characteristics, and in-use performance characteristics. The compositions contain one or more oral composition components selected from abrasives, binders, humectants, surfactants, fluoride ion sources, anti-calculus agents and sweeteners and additionally contain a dimethicone copolyol selected from alkyl- and alkoxy-dimethicone copolyols of formula (I): wherein X is selected from hydrogen, alkyl, alkoxy and acyl groups having from 1 to 16 carbon atoms, Y is selected from alkyl; and alkoxy groups having from 8 to 22 carbon atoms, n is from 0 to 200, m is from 1 to 40, q is from 1 to 100, the molecular weight of the residue (C2H4O-)x(C3H6O )yX is from 50 to 2000, preferably from 250 to 1000 and x and y are such that the weight ratio of oxyethylene:oxypropylene is from about 100:0 to about 0:100, preferably from 100:0 to 20:80.
