What causes a diastema?
Diastemas can be caused by a mismatch between jaw size and tooth size, an oversized labial frenum (the strip of skin between your lip and gums), or habits like thumb-sucking or tongue-thrusting in childhood. Gum disease can also cause teeth to shift and create new gaps.
Gaps in baby teeth are completely normal — most close on their own as adult teeth come through.
