Repair a pin hole dent

Q: How do I repair a dent in an oak floor, with a depth about the size of a pin head and a width about the size of 2 pin heads?

I know it’s small, but my wife notices it when the sun hits it just right.

A: This isn’t your dining room table. It is a floor. We walk on them. Buy a tube of colour match filler and fill the “pin hole”.
