If you have a pre finished hardwood where they have filled the knots. ocer time when the filler comes out. Is there anything to use to re-fill the knots it is about the size of a dime. Thanks for any help

I normally like to use wood wise prefinished filler.

The size of these holes makes me think you might fill some of the space with smaller chunks of wood to take up some of the space and give the filler a bit more strength.
