Songs by Lorde that mention teeth:
* 400 Lux
* Green Light
* Royals
* Team
* White Teeth Teens

The fact that teeth are a recurring theme
in her songs has been noted by others
before.

Thoughts:

 Teeth are an indicator of health. We
 subconsciously judge people by their
 teeth.

 It is said that bad dental hygiene can
 cause you health problems elsewhere too.

 Teeth, or rather the fear of losing them,
 can be seen as a symbol of aging.

 Teeth can be seen as a symbol of how we
 "digest" our impressions of the outer
 world.
