Well, Sadie says she sometimes acts as a " periodontist." What, you ask, is a " periodontist" (periodontist)?

好吧，Sadie说她有时会充当“生”。 你问，什么是“生” （periodontist）？

In that case, since I live in a small town, I do basic dental work, but also act as a periodontist, oral surgeon, and orthodontist when the need arises.

Sadie：那种情况下， 因我一个小镇，我做基本的科工作， 但需要时也会担任生、口腔外科生和齿矫正生。

Because Sadie lives in a small town, not only does she sometimes do work related to the work of a periodontist and an oral surgeon, but she also acts as an " orthodontist."

因Sadie一个小镇上，她不仅有时会做一些与生和口腔外科生相关的工作， 她还充当着“齿矫正生” 的角色。

A periodontist would be a dentist who is very knowledgeable and specializes in taking care of the place where the teeth go into your mouth – your " gums" (gums) – and other parts of the structure of the jaw.

生是一位知识渊博的，专门负责照顾齿进入口腔的地方——你的“龈”（龈）——以及下颌结构的其他部分。
