I was making a cup handle so I extruded a face of the cup, then however I right clicked and thought that would undo it. I didn't notice the dent it left though, after that I did a bunch of smoothing on the cup and then when I went back to extrude it, it didn't create the smoothing I wanted. That's when I noticed the dent, I decided to make the handle on a different face, but is there any way I can remove the ugly dent?
P.S I am a beginner so please don't be angry with me for thinking right click was undo.
P.P.S Cup is on layer 2.
