Could someone please explain to determine the denticity of a ligand based on its Lewis structure?

The easiest way to do it is to look for Nitrogen molecules and COOs and find their available binding sites. For example, if Nitrogen has 3 bonds, this means it has one lone pair that acts as a binding site. A monodentate has one binding site, bidentate has two, and so on.

Adding onto Paige's answer, you also need to use the shape of the molecule to determine the denticity of a molecule. If the shape of the molecule does not have lone pairs close enough for the metal cation to bond, then the ligand will differ in Denticity.
