Teeth, as they exist in the mouth, can be placed into any of three broad groupings, the maxillary or mandibular, right or left, anteriors or posteriors. These groupings apply to both the natural dentition and to artificial teeth:  Maxillary or Mandibular. A person has two jaws, a maxillary (upper) and a mandibular (lower). The teeth in these jaws are called either maxillary or mandibular teeth. The combination of natural teeth and supporting alveolar bone that is found in an upper or a lower jaw is called a dental arch .
For the 1908 film based on the poem, see The Song of the Shirt (film). The Song of the Shirt is a poem written by Thomas Hood in 1843. It was written in honour of a Mrs. Biddell, a widow and seamstress living in wretched conditions. In what was, at that time, common practice, Mrs. Biddell sewed trousers and shirts in her home using materials given to her by her employer for which she was forced to give a Â£2 deposit.
