there is many ways to do it. it depend what your hole is and what your object is
check clipped_by{}, bounded_by{}, difference{}, intersection{}
if you want remove exat triangle then it is better to store vertices in some
structure (mainly array) and remove vertices from this structure first and
create mesh at final stage
