In more advanced contexts, you might encounter "sún" in discussions about dental health, health education, or when discussing the effects of sugar on teeth.
While "sún" primarily refers to dental decay, it can also be used more metaphorically in some contexts to describe something that is deteriorated or in a bad condition.
