Gap between front teeth: why it happens and how to close it.
A space between the two front teeth, called a diastema, is one of the most common reasons people visit an orthodontist.
From the orthodontists at NA Orthodontics, North Arlington, NJ
Common causes
- Normal growth in children while adult teeth come in
- Teeth that are small for the jaw, or missing teeth
- A low frenum between the front teeth
- Habits like thumb sucking or tongue pushing
- Teeth shifting from gum problems
Kids: when to wait
Many children have a gap that closes on its own. We recommend a first orthodontic check around age 7 so we can tell you whether to wait or treat early.
Teens and adults: closing the gap
Invisalign and braces both close gaps. Our orthodontists look at your bite as a whole, since closing one space may affect others. Sometimes we coordinate with your dentist for bonding if teeth are small.
Keeping it closed
Gaps tend to reopen without a retainer. We set you up with a retainer plan at the end of treatment.

Frequently asked questions
- Is a gap between front teeth normal in kids?
- Yes. Gaps are common while baby teeth are falling out and adult teeth are coming in. Many close as the canines erupt. A check at age 7 tells you whether to wait.
- Can Invisalign close a gap between front teeth?
- Often, yes. Aligners and braces both close gaps. Our orthodontists choose based on the cause and your whole bite.
- Will the gap come back?
- It can, which is why retainers matter. Some patients get a thin bonded retainer behind the front teeth to keep a closed gap closed.
- What about the tissue between my front teeth?
- A low frenum, the small band of tissue above the front teeth, can sometimes keep a gap open. If so, we coordinate with your dentist or a specialist.
