Diastema causes and treatment options
A diastema is a space between teeth, often from tooth size, jaw growth, a frenum, habits, or missing teeth, and treatment depends on its cause.
The short answer
A diastema is a visible space between two teeth, and treatment may involve monitoring, orthodontics, bonding, veneers, or care for an underlying gum or frenum problem.
Why might a space develop between your teeth?
A gap can result from teeth that are small relative to the jaw, a thick labial frenum, missing teeth, a tongue-thrust habit, gum disease, or an unerupted tooth. A new or widening gap in an adult needs assessment because tooth movement can reflect periodontal support changes.
How is a gap between teeth assessed?
A dentist examines the teeth and gums and may take photographs, dental radiographs, or scans. Orthodontic movement closes or redistributes space, while composite bonding or veneers change tooth contours after the teeth and gums are suitable for restoration.
When should a new or widening gap be checked?
Seek care when a gap appears suddenly, increases, bleeds, becomes painful, or is associated with loose teeth, bad breath, or swollen gums. Children should be assessed if a permanent tooth is delayed or the space is accompanied by an abnormal eruption pattern.
What should you ask about closing a tooth gap?
Ask what caused the space, whether the gums and bone are healthy, whether imaging is needed, and which option preserves tooth tissue while matching your bite and cosmetic goals.
Frequently asked questions
Does every diastema need closing?
No. A stable gap with healthy teeth and gums may be monitored when it does not affect function or the patient’s goals.
Can bonding close a small gap?
Composite bonding can add tooth-colored material to selected tooth edges, but the teeth and gums should be assessed first.
