It is an image of a tooth. There are two medium length roots at the bottom, they are fairly symmetrical. The top is rounded and divided into two bumps, with a short diagonal line in the middle to indicate the groove in the tooth.
This Tooth icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest
Microsoft Office, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,700 icons, all in the same style and quality.
