A dent is a small depression or indentation on a surface, often caused by an impact or pressure. Dents can occur on various materials, including metal, wood, and plastic. Common examples include dents on cars, furniture, or appliances, which can affect their appearance and value. Dents are typically measured by their depth and diameter. Repairing a dent may involve techniques like pulling, filling, or sanding, depending on the material and severity. In the automotive industry, specialized tools and methods, such as paintless dent repair, are often used to restore the original shape without damaging the surface finish.
