What it is
A diastema is a visible gap between two teeth, most often between the upper central incisors. It can be due to a mismatch between tooth size and jaw size, a prominent lip frenum, or the loss of a neighbouring tooth.
How it’s closed
The approach depends on the cause and the size of the gap. When the gap is wide or several teeth are poorly positioned, the most stable solution is orthodontics, which moves the teeth to their ideal position. For small gaps with teeth that are already aligned, a veneer or a composite reconstruction within dental aesthetics can close the gap in a single visit.
- Visible gap between the central incisors or other teeth
- Diastema affecting speech or the appearance of the smile
- Gaps caused by the loss of a tooth or a prominent lip frenum
What the process looks like
- Diagnosing the cause We assess whether the gap is due to tooth position, tooth size or a lip frenum, since each cause needs a different approach.
- Choosing a technique Orthodontics to move the teeth and close the gap permanently, or composite/veneers when the gap is small and the teeth are already well aligned.
- Treatment and adjustment We carry out the chosen treatment and review the result to ensure a harmonious smile.
Frequently asked questions
What's better, orthodontics or veneers, to close a diastema?
It depends on the case: orthodontics moves the tooth to its ideal position more permanently; veneers or composite close the gap visually in a single session, but without correcting the tooth's actual position.
Can the diastema reopen after orthodontics?
It can happen, especially if there's a prominent lip frenum that hasn't been corrected. That's why we assess this possibility before deciding on treatment.
Is it only a cosmetic treatment?
Generally yes, although some wide diastemas can also affect speech or make it easier for food to get trapped between the teeth.
