「櫛の歯が抜けたよう」 is a variant of 「櫛の歯が欠けたよう」 and is sometimes used with the same meaning.
A variant of the idiomatic expression 櫛の歯が欠けたよう, literally 'like a comb with missing teeth', where 欠けた (chipped/missing) is replaced by 抜けた (fallen out). The origin of this variant is uncertain, but it may arise from a similar mental image of gaps.
