A diastema is a space or gap between two teeth. It appears most often between the two upper front teeth. However, gaps can occur between any two teeth.

A mismatch between the size of the jaw bones and the size of the teeth can cause either extra space between teeth or crowding of teeth. If the teeth are too small for the jaw bone, spaces between the teeth will occur. If the teeth are too big for the jaw, teeth will be crowded.

There is a range of treatments to remove the gaps, depending on the case and desired results. These include orthodontics, tooth-coloured fillings, porcelain crowns and veneers.

If your lateral incisors are too small, our dentists may suggest widening them using crowns, veneers or bonding.Some people get braces, which move the teeth together. Often, no matter where the diastema is, you must wear a full set of braces — on both your upper and lower teeth. That’s because moving any teeth affects your entire mouth.
