Yes, you can absolutely use wood filler on a door frame for cosmetic fixes like dents, nail holes, gouges, or minor cracks. However, for load-bearing areas (like where hinges attach) or major rot, a two-part wood epoxy or replacement is usually required.
Wood filler is a trusted way to fill in gaps in your wooden doorframe. Wood fillers have the ability to soak into the wood fibers and bond to them. Then it hardens and is able to be sanded for a good finish.
The best filler for a door frame depends on the type and size of the damage: two-part wood epoxy is best for deep gouges or rotted wood, acrylic latex caulk is best for sealing seams and gaps along the casing, and high-quality wood filler is ideal for minor nail holes and dents.
The material you should use depends on the size and location of the gap:

Wood filler and wood putty are very different products. Wood filler hardens and is meant to be sanded and used on raw wood before staining or painting. Wood putty remains pliable, doesn't harden, and is applied after wood is finished (stained and sealed) to conceal minor blemishes.
What to do: For small gaps less than 5mm use exterior grade caulk or sealant. Medium gaps (2-20mm) should be filled with foam if needed and then finished with exterior grade caulk or sealant. Large gaps (20mm+) use expanding foam to fill the void, or a foam backer rod inserted into the gap.

Sometimes, repairing a door frame is more cost-effective than replacing it. The cost to fix a door frame can vary between $50 and $200, depending on the extent of the damage. Small cracks or dents can often be patched and painted over, saving you the cost of a full replacement.
To use wood filler on a door, clean the damaged area, press the filler firmly into the hole using a putty knife, and overfill it slightly. Let it dry completely according to the package, then sand it flush with the surrounding wood and prime or paint.
To fill holes in a door frame, first clear away debris and loose wood. For small holes or stripped screws, pack the space with wood glue and wooden toothpicks, then cut them flush once dry. For larger dents or deeper holes, use a two-part wood filler like 3M Bondo Wood Filler.
Hollow-core doors tend to have a strong outer frame at the top, bottom and sides, which means that they can be trimmed. Again, you don't want to cut too much away or you'll risk damaging its structural integrity and have to replace the outer frame.

Wood filler is suited for unfinished wood and hardens for sanding and staining. Wood putty is ideal for finished wood, remains pliable, and is better for outdoor use. Use wood filler indoors due to its tendency to shrink and crack outdoors.
To fix a cracked door frame, clear loose wood debris and inject wood glue deep into the crack. Clamp the frame together until dry, fill any gaps with wood filler, sand smooth, and paint to match. For structural splits (like forced entry), reinforce the jamb with 3-inch wood screws.
Avoid using expanding foam around electrical boxes, near high-heat sources (like recessed lights or chimneys), inside hollow structural cavities prone to moisture, or for large leaks. Using high-expansion foam around windows and doors can also warp frames, preventing them from closing properly.
Yes, you should caulk around a door frame, specifically where the trim meets the wall. Caulking creates a clean, professional paint finish and stops air drafts. However, never caulk between the door and the moving door slab, as this will glue the door shut.
