As kitchen drawers age and undergo continued use, the front may become loose or even pop off. If this occurs, the drawer's contents can spill out onto the floor. There are two solutions to a broken drawer front: build a new but similar looking drawer assembly or repair the existing drawer front. The former requires a substantial degree of carpentry skills while the latter can be done by practically anyone willing to take on the fix.
Empty the drawer and set its contents aside.
Pull the drawer out and off the slides. On some drawers, there will be a tab you'll have to depress on either side to free the drawer from the slide rails.
Put a dust sheet down on a workbench or table and then lay the drawer on top of it.
Pull the drawer front off, if still attached. Pull out any protruding nails with pliers.
Spread a bead of glue around the front edges. Press the drawer front back into position, setting it against the glued edges.
Fasten the drawer front to the drawer frame with wood nails using a hammer. Place clamps on the drawer front and allow the glue to sit overnight.
Reinstall the drawer into its place in the kitchen and put the contents back inside.
