歯はおそらく地球上で最も広いです。

前歯の間の隙間は、ジアステマと呼ばれます。特に子供にはジアステマは一般的であり、子供の顎が成長し、歯が位置に移動するにつれて、通常は自分で閉じます。ただし、一部の大人は持続的な拡張腫を持っています。彼らは、歯を装具や他の矯正治療でまっすぐにすることを選択できます。

There are a number of ways to treat diastemas, depending on the severity of the gap and the patient's individual preferences:

- Braces:Braces are the most common treatment for diastemas. They work by gradually moving the teeth into place over time.

- Invisalign:Invisalign is a clear aligner system that can be used to treat mild to moderate diastemas. Invisalign is less noticeable than braces and may be a better option for adults who are concerned about their appearance.

- Dental bonding:Dental bonding is a procedure in which a tooth-colored resin material is applied to the teeth to close the gaps. Dental bonding is a less expensive option than braces or Invisalign, but it is not as durable and may need to be replaced over time.

- Veneers:Veneers are thin porcelain shells that are bonded to the front of the teeth. Veneers can be used to close gaps, change the shape of the teeth, or whiten the teeth. Veneers are a more expensive option than braces or Invisalign, but they are very durable and can last for many years.
