the-BA : Toothbrush design

A Glasgow dentist has been awarded £75,000 to develop a new toothbrush handle that increases control and cuts joint strain. The dentist, 50-year-old Glenn Heavenor, said: “When I sanded that first design in the bathroom it was like giving birth to a toothbrush.” How he knows what it’s like to give birth to a toothbrush, we’ll never know.

Have you ever wondered if the brush you use affects the cleanliness of your teeth? Are electric brushes better?

You might like to …

Stain some teeth (if you can’t get any teeth, egg shells can be used instead – they have similarly high calcium content) with some form of dye. Clean them with different types of tooth brush to see which is best
Try to work out if certain types of brush work better on certain types of stain
Find out what toothbrush bristles are made from. Devise a test to work out how long they remain useful (in other words, how long until they lose their cleaning power).
