A competition to design a new toothbrush has been won by a nine-year-old.

Ambria Schneringer, a nine-year-old fourth-grader from Ripon, California has won a competition to design a new toothbrush.

The annual competition was run by Dr Fresh as part of National Children’s Dental Health Month in the US, with the aim of the competition being to make kids more aware of the need for regular brushing and hopefully making them excited about dental health by designing their own toothbrush.

Ms Schneringer noted: “You never hear parents nagging their kids to play video games, right? Well, my toothbrush is similar to a video game. It will light up with different colours and levels as you brush.”

Elsewhere, researchers for the Cochrane Oral Health Group recently highlighted the importance of fluoride in helping children’s teeth stay healthy.

A study by the organisation revealed a minimum concentration of fluoride in children’s toothpastes of 1,000 parts per million could have a significantly positive impact on oral health.
