What is the primary requirement to raise dents in wood?

The primary requirement to raise dents in wood involves using a blow dryer, old towel, and a cup of water. This method utilizes steam to expand the wood fibers that have become compressed due to the dent. By applying heat from the blow dryer, it encourages moisture from the towel (which is moistened with water) to penetrate the wood fibers. The steam generated helps to swell the fibers, effectively lifting the dent back to its original level.

This technique is practical and does not require special tools or professional assistance, making it an accessible solution for anyone looking to repair the appearance of their wood surfaces. Other options such as heavy machinery or special tools are not necessary for this simple, effective method of wood dent repair.
