Diastema is a space or a gap that is found between two teeth.
It will appear more often between the two upper front teeth although it can occur between any two teeth.
A mismatch between the size of the jaw bones and the size of the teeth will cause either spaces between the teeth or a crowding of the teeth.
If the teeth are too small for the jaw bone then there will be spaces between the teeth while if the teeth are too big for the jaw bone then the teeth will be crowded.

Isolation, rubber dam, proper measurements and the right composite material will ensure a successful diastema closure on every case.
