Question

My aunt ____ a root canal done yesterday because her tooth was rotten.

Answer 1

my aunt got a root canal done yesterday because her tooth was rotten.

Answer 2

Answer:

The right answer is

"My aunt "got" a root canal done yesterday because her tooth was rotten".

The noun in this sentence is root canal. To describe the action related to the noun, a verb needs to be used. The "past tense form" of has (had) is an option but the one that goes with the sentence is the past form of get (got). Using got, adds the right meaning to the sentence.
