Colgate release toothbrush with phone app after gap in revealed in tooth-brushing skills

Colgate has released a toothbrush which can sync with a smartphone app for health advice after research indicates most Australians "miss 40 per cent of their teeth" when brushing, according to Tech Guide Editor Stephen Fenech.

"There are sensors in the brush-head that tell you exactly what you've covered and for how long," Mr Fenech told Sky News Australia.

"In the hands of a child - it is going to set them up to have great brushing habits."
