The iWhite Instant Whitening Mouthwash is a mouthwash with “triple action” ingredients for daily use. Shake the bottle vigorously before use to activate the "triple action". The presence of blue covarine in the formula gives an immediate visibly whiter appearance with just one use. The mouthwash removes and prevents new plaque formation which results in a more intensely white, bright smile. The iWhite Instant Whitening Mouthwash dissolves tooth discolouration without causing damage to the teeth or gums. Further, the formula contains fluoride to strengthen your teeth.
