It will be no revelation to find that the image above depicts a denture, a prosthetic device designed to replace missing teeth. It is not immediately clear which cavities would have the pleasure to be filled by this specimens, but my guess would be the top front ones, known in the world of dentistry as the central incisors, as the two teeth are of similar size and shape. But this is only a guess.
