How many toothbrushes are sold in London everyday?

How many toothbrushes are sold in London everyday?

In summary we first need to know the population of London and then work out how often Londoners change their toothbrush in a year.

The population of London is around 9 million. Of the total population let's assume that ages 1 to 3 and 75 and above do not need to brush their teeth. Assuming average life expectancy of the total population @80 years that leaves us with 90% of the population using a toothbrush everyday. So we have 8 million teeth brushing Londoners daily.

Assuming that on an average Londoners change their toothbrush every 4 months we get an average Londoner needing 3 toothbrushes a year. i.e. 24 million toothbrushes sold in a year. Dividing this by 360 days we get 66,667 toothbrushes sold everyday in London.
