How to repair nail holes?

Tooth paste is what I have used before (college days) but wood putty would be a better fix

Here is the right way:

Some people use putty, toothpaste, zinc oxide.

Use toothpaste. Or Spackle- it's easy.

My mother-in-law never wanted to hang anything in her home because she was afraid of leaving nail holes. My wife however rearranges wall decor all the time. Nail holes are very simple.

You will need spackle, a small putty knife, and 120 grit sandpaper or a fine sanding sponge. Keep these together and they will last years.

Fill the holes with the spackle and let it dry. (Dap spackle has a pink dye which fades away when it is dry, convenient.) Lightly sand the spackle until it is smooth and flat with the wall. It sometimes shrinks and you will need to do it a second time. Wipe the wall with a dry cloth and touch up the white spot with matching paint.

You can use this technique for and small in your wall.

Quick fix? Plain old fashioned, white toothpaste. Put a small glob on the hole, push it in with your finger, wipe around the hole with a damp cloth ( don't remove the plug of toothpaste).

Better fix? Soft spackle from hardware store. This stuff is so light, you'll think the small tub is empty. Just a dab on the hole, wipe off excess.

I have even covered up cracks in walls with this stuff. Put it on with my finger. So easy to use.

Big nail hole? Cut wooden toothpicks to fill the hole, make sure they are flush with the wall, or just inside the hole, and use the soft spackle.

Almost instant fixes!
