A diastema is not considered part of normal dental development
Does diastema get worse as you get older?
Diastema is not considered a normal part of tooth growth after eruption of the permanent canines. Diastema is common, and most health care professionals see it as a normal variation of how teeth grow and develop. There is a diastema if one or more of the teeth is significantly smaller than the others. These are the teeth to the upper left and right of the central incisors, and they are the most common ones to experience this problem. A gap can develop in front of your teeth if your upper lateral incisors are small or absent. There isn’t just one cause of a diastema; rather, there are several things that could be to blame.
