Dentations are small indentations or notches, often found along the edges of objects or surfaces. Synonyms for dentations include serrations, indentations, notches, crenulations, teeth, ridges, and grooves. Serrations typically refer to small, sharp teeth or notches along a cutting edge, such as on a saw blade or the edge of a leaf. Indentations and notches are more general terms and can be used to describe any type of small depression or groove. Crenulations are closely spaced, small notches or projections, often found along the edges of a surface. Teeth, ridges, and grooves are also general terms that can be used to describe various types of irregularly shaped indents or projections along a surface.
