Final answer:
The poetic devices used in the poem are personification and metaphor.
Step-by-step explanation:
The poetic devices used in the poem are personification and metaphor.
Personification is when human qualities are attributed to non-human objects or concepts. In this poem, the bride is personified as a vampire bride who drinks the warm life-blood of the groom.
Metaphor is a figure of speech in which a word or phrase is applied to an object or action to which it is not literally applicable. In this poem, the bride's teeth are metaphorically described as being beneath the groom's heart, representing her power over him.
