Now, all that one has to do is rub the stick against the gum twice, once against the upper jaw and then on the lower jaw, from one end to another, to collect oral mucosal transudate fluid, normally secreted in the oral cavity.

If the crevice between teeth is getting bigger and explain oneself have a tooth disease for week, and the gum atrophiesed and increased wide illusion by crevice between teeth for person after cleaning tartar.

如果牙缝大了，说明本身就有牙周病，而且牙龈萎缩了，去除牙石后给人以牙缝增宽的错觉。

2007年5月至2009年8月在北京大学口腔医院种植中心接受上颌前牙种植修复的患者10人（男4人，女6人，平均年龄41.5岁）共14个牙位，种植体骨结合完成后采用种植体支持的暂时冠对牙龈成型3~6个月。

Meanwhile, the blood supply to the pulp and the roots of the teeth atrophies, and the flow of saliva diminishes; the gums tend to become inflamed and pull away from the teeth, exposing the base, making them unstable and elongating their appearance, especially the lower ones.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
