Dentated refers to something that has a toothed or serrated edge. There are a variety of synonyms that can be used to describe this characteristic, including serrated, toothed, jagged, notched, sawtooth, toothy, crenated, and denticulate. Serrated and toothed are perhaps the most commonly used synonyms, as they accurately convey the meaning of a surface that is marked by small teeth or ridges. Jagged and notched are also popular synonyms for dentated, as they suggest a rough or irregular edge that is similar to what one might encounter on a saw blade or some other sharp implement.
