What is wood filler?
Wood filler or wood putty is made to do exactly what it’s called – fill in holes and imperfections in the wood. If you’ve ever felt it, it feels like wet, sticky sawdust in my opinion. That texture is what helps it blend in with the texture of the wood (as opposed to caulk that stays smooth and shrinks).

How to fill in a gap in a miter joint?
It is best to use this option when the void is large enough and regular in shape. If the void is irregular you can straighten it out with a back saw or dovetail saw. Use a chisel to take a sliver from another piece of matching wood, but be sure to make it deep er than the gap. Rub the sides of the sliver on sandpaper until it fits the width of the gap perfectly. Then force the glue into the opening with a knife or a piece of paper and slip the filler into place. Wait after the glue dries and then use the flat face of a chisel to trim the protruding filler piece flush with the surface of your project. Follow that with light sanding and you will have a perfect miter joint.
How to fix a small gap in a wall?
Just firmly clamp the members of the joint at the angle needed and gently run a fine tooth saw (a back saw or a dovetail saw works perfectly) down the joint between the two pieces. When finished, slide the members of the joint together and fasten in place with glue or nails. If your gap is larger then bring the two members of the joint together and run the saw between them again. Don’t worry, in most cases, you will not create a fit problem for the other joints by removing a tiny bit more material at this corner.
