Dental Opinion, Toothbrush vs Mobile Phone
4 billion people use a mobile phone only 3.5 uses a toothbrush
According to 60 Second Marketer contributing writer Nicole Hall, “Based on the research we’ve conducted, we feel that there are almost certainly more mobile phone subscriptions than there are toothbrushes on the planet. And, if you make some additional assumptions based on our research, in all likelihood, more people own a mobile phone on the planet than own a toothbrush.”
