There are several reasons why some people's teeth grow in crooked, overlapping, or twisted. Some people's mouths are too small for their teeth, which crowds the teeth and causes them to shift. In other cases, a person's upper and lower jaws aren't the same size or are malformed, resulting in either an overbite, when there is excessive protrusion of the upper jaw, or an under bite, when the lower jaw protrudes forward causing the lower jaw and teeth to extend out beyond the upper teeth.
Types of teeth alignment problem:
1. Upper front teeth jutting out (excessive)
2. Lower front teeth jutting out (overbite)
3. Upper teeth behind lower teeth
4. Front teeth do not touch
5. Too crowded teeth
6. Less teeth and teeth spacing
7. Teeth spacing
8. Deep bite and lower front teeth cannot be seen
9. Extra teeth
Check if you having teeth similar to any pictures above. All of them are treatable, remember to consult your dentist.

牙齿不齐/牙齿错位
我们的牙齿不整齐，歪斜，重叠，暴牙等等其实有几个主要的原因。有些人的嘴巴太小，没有办法容纳他们的牙齿，在拥挤的情况下，有些牙齿就会被推挤造成牙齿不齐及重叠。另外，在其他情况下，一些人的上颌和下颌的大小不同或有异常。上颌过渡突出或下巴过小，导致上面的牙齿远超下面牙，形成了所谓的上牙突出（俗称暴牙）。而当下颚过渡的向前突出，导致下巴明显的突出（月形脸），使下巴和牙齿出超出上面的牙齿。
牙齿排列问题类型：
1 . 上门牙突出/暴牙（过度）
2 . 下颚牙突出
3 . 上牙在下牙后面
4 . 上下门牙不能咬合
5 . 过于拥挤的牙齿
6. 牙齿少和牙齿间距
7. 齿间距
8. 咬合深，看不到下前牙
9 . 多出来的牙齿（额外牙）
记得检查看看是否您或家人朋友的牙齿是否有类似上述的任何图片。这些问题都是可以治疗的，记得要咨询您的牙医。
