Hi.. I have to warn u that the more harder u brush the more yellow your teeth become because the outer WHITE ENAMEL layer of teeth is abraded off with hard brushing and the inner YELLOWISH sensitive DENTIN layer gradually gets exposed. Also, tooth colour is genetic( after ruling out stains etc). If u have no sensitivity u can go for Tooth Bleaching to whiten them
