The story

李医生：治疗做完了。要避免下次再来，你们要给他刷牙。The treatment's done. To avoid coming back, you'll have to brush his teeth.

李医生：对。在我们这个行业，这很正常。每天刷一次，一个月，他的牙就会改善很多。Yes. In our trade, that's quite normal. Once a day, and in a month, his teeth will improve a lot.

李医生：还有，你的手要避免跟他的牙接触。Also, your hand must avoid contact with his teeth.

大卫：不接触牙，怎么刷牙？Without touching his teeth, how do I brush them?

李医生：牙刷接触牙。手不接触。The toothbrush touches the teeth. The hand doesn't.

大卫：李医生，您来刷吧？Dr Li, won't you do the brushing?

李医生：这不符合我们机构的规定。That's against our organisation's rules.
