Can I fill and paint old stairs or do I need retreads?

Stairs hidden under carpet are often made of two separate pieces of wood with a noticeable gap, plus leftover nail and staple holes. You can fill the holes and paint the boards to use them as functional stairs temporarily, but you will need to purchase new treads to permanently fix the gaps.

“It’s not noticeable under the carpet and padding but she wanted to rip it up- the wood looks to be in pretty good condition but we’re not sure how to remedy the gap”source ↗

“So could the carpet be ripped up and these be painted and used as functional stairs until treads can be purchased?”source ↗
