I like aqua fresh toothpaste in pump but it discontinued only pump is kids one in aqua fresh is ok for adult to use it? i like pump better

Yes, it's fine: Yes, am adult can use children's toothpaste. Some children's tooth paste may have less fluoride then the adult version, otherwise the difference is mostly taste and marketing strategy. The physical act of brushing the teeth with the toothbrush does most of the work in cleaning your teeth. Use what ever toothpaste you like best so that you will brush longer.
