Would be a hit if the Superbrush toothbrush was on offer (smaller version, for children).

-The teeth are cleaned thoroughly and gently on all sides at the same time
-the Superbrush cleans better in less time
-insides and outsides are cleaned equally
-slanted bristles clean the gum line and thus ensure healthier gums
-very easy to use, for both children and adults
-The Superbrush is also very helpful for people with limited motor skills.
