Ergonomics: Tennis balls, sponges, silicone handles, and other contraptions are used to increase the grip size of a tooth brush. These types of aides are designed to help those who otherwise are unable to hold a thin-handled brush. The elderly or anyone suffering from severe arthritis can typically benefit from such modifications.
