Fill gaps between the pieces of your crown molding or cracks in the molding with a gap-filling adhesive. Remove any excess and let the material dry. If needed, cover the material you have applied with appropriate spackle. Use sandpaper to even out the surface, and then paint over your changes.
Just sand enough until it is smooth and then caulk it, only filling the gap and wiping away the excess caulk with a damp cloth. You could use some wood filler or something, but all fillers are brittle and will eventually crack/fall out, which is why caulk is usually a better option.
Just patch it with caulk or spackle. If spackling hit it with a light sanding from sandpaper after it's dry. Apply some primer, paint and you're done.
I use caulking to fill those small gaps and cracks that form between trims pieces, and, between the trim and the wall.
Caulk, sealants, expanding foam, backer rod, grout, and mortar are among the most commonly used substances for this purpose, offering versatility and durability in different contexts. When selecting the appropriate material for filling a particular gap, several factors must be taken into account.
Fill in gaps between your crown molding and ceiling by using Loctite PL Heavy Duty Sealant or Loctite Polyseamseal All Purpose Adhesive Caulk. Spread the material along the gap and smooth it over. Remove any excess, let it dry, and paint over the molding.
Heat and Cold
Even gradual changes in temperature can dislodge or fracture parts of your crown molding. Maintaining a consistent interior climate is one way to keep your crown moldings secure and sound (and protect your home painting as well).
PROS: Acrylic caulk is often the recommended type of sealant because it allows contractors to paint over it. It is also much easier to clean up than silicone sealant, which can help you achieve a pristine finish. Acrylic caulk is mold-resistant, preventing harmful growth inside the cracks of your crown molding.
Crown moulding is made from wood, and wood expands when it is exposed to moisture. When this happens, the paint can start to crack and chip. Moisture often gets into crown moulding when it has not been sealed properly. It can also happen when there is flooding from something like a broken pipe.
Regardless of how well-installed your crown molding is, it's always a good idea to caulk both the top and bottom. This is the best way to ensure a uniform look and get rid of any unsightly gaps that may be present.
You'll use construction adhesive and a brad nail gun to attach the molding to the wall and, when you can, to ceiling joists.
Crown molding adds elegance and sophistication to any room, so long as it's installed with the right backing strips. You install these strips behind the molding to provide a solid foundation and keep the trim tight and gap-free.
Caulk the miters (corner joints of baseboards)
To caulk the inside miters, run a thin bead of caulk from the bottom edges of the miters to the top. Then, dampen your finger and run it along the bead to press it into the corner.
Gum Grafting: For gaps caused by gum recession, gum grafting can restore the gum line. This procedure involves transplanting healthy gum tissue to cover exposed areas. Crown Lengthening: In some cases, crown lengthening might be necessary to remove excess gum tissue.

I use joint compound to fill all nail holes on trim that's to be painted. I used to use caulk before this veteran carpenter gave me the tip. You hardly need any of it and it sands perfectly smooth before paint. However if it's foam just use a wet rag to remove whatever excess there is.
The distinction between both materials is that the baseboard is designed to be flat, while crown molding is usually angled. Several homeowners often want certain rooms to have a sophisticated appearance by matching both. In addition, baseboard is often found in homes because of its aesthetic and functional purpose.
Small dings, scratches, and cracks can be repaired using wood putty. For larger areas with more extensive damage that requires it to be rebuilt, such as deep gouges or broken corners, epoxy filler is a better option. If you are repairing stained wood, be sure to select a stainable wood filler.
Generally, silicone is most effective for small to medium-sized gaps, typically ranging from ⅛ inches to ½ inches. Attempting to seal large gaps with a single application may result in collapse or shrinkage. When facing wider gaps, epoxy-based sealants or specialized gap-filling products may be a better choice.
Gaps between wall and floor most commonly occur due to an unlevel foundation. Baseboards separating from the walls are also standard. Soil irregularities beneath your home can cause parts of your foundation to sink or settle at different rates, leading to visible gaps.
