No matter how comfortable you are with someone, it can be awkward to inform them of a post-supper stowaway still wedged between his pearly whites, which is why the Toothpict app is particularly useful.
Picture a dinner party, and your unfortunate friend is sporting some bits of herb between his front two teeth, but it would only embarrass him to point it out aloud. The solution comes in the form of a discrete technological solution. Download this iPhone application, complete the cartoon diagram which highlights the location of the speck, and send it to your pal through SMS or email. On the other hand, if announcing the presence of a piece of lettuce between somebody's teeth isn't quite public enough, you can use the Toothpict app to post the picture on Twitter.
