When one smiles by bearing only the bottom row of incisors. It may take some practice, however there is nothing more heart-warming than seeing one smile with his or her bottom teeth. Please note, these teeth should gently pull down the upper lip, raised on either side as per any smile.
Look at that bottom-toothed smile. It's so endearing .. and makes for the perfect photo on greeting cards!
