Crooked teeth are a common condition that can negatively affect chewing function and overall oral health, in addition to aesthetic concerns. The misalignment of teeth at different angles than they should be within the jaw structure can be observed not only in adults but also in children and even babies. It usually occurs due to genetic factors, oral habits, or developmental problems.

What Are Crooked Teeth?

The deviation of teeth from their proper alignment on the jaw, their crowded or anterior-posterior positioning, leads to crooked teeth. It is a condition that can cause aesthetic concerns in individuals due to the lack of a symmetrical appearance. Additionally, depending on the degree of crowding, it can affect functions such as speech, chewing, and teeth cleaning.

牙齿不齐可表现为牙齿重叠、牙缝（牙间隙）或颌骨错位（错颌畸形）。这种情况还会增加刷牙和使用牙线的难度，从而提高龋齿和牙龈疾病的风险。

What Causes Crooked Teeth?

The most common causes of crooked teeth are genetic factors, narrow jaws, and early loss of primary teeth. Additionally, habits such as thumb sucking and subsequent tooth loss can also lead to crooked teeth.

General causes include:

  • 遗传因素

  • Bad oral habits

  • Narrow jaw

  • 乳牙过早脱落

  • Thumb sucking

  • Prolonged pacifier use

  • عادة صرير الأسنان (الصرير السني)

  • Shifting in spaces after tooth loss

Crooked Teeth in Children

In children, this condition often results from hereditary traits or early primary tooth loss. However, during childhood, when jaw development continues, teeth may emerge crooked if they struggle to find space. During this process, issues such as mouth breathing and incorrect swallowing can also affect the jaw structure and contribute to crooked teeth.

Crooked Teeth in Babies

婴儿出牙期间，乳牙略微歪斜通常无需过于担心。虽然可能出现轻微的排列偏差，但这属于暂时性的发育现象。同时，乳牙的位置并不会影响恒牙的萌出。然而，如果婴儿长期有吮拇指或使用安抚奶嘴的习惯，这些行为可能为日后的错颌问题埋下隐患。若怀疑牙齿不齐已成为永久性问题，建议咨询儿童牙科医生。

How Are Crooked Teeth Straightened?

治疗方法包括正畸和美学两类选择，如牙套、隐形矫正器和瓷贴面。确定治疗方案时，需综合考虑牙齿不齐的程度、患者年龄及颌骨结构。其中，传统牙套仍是最常见的治疗方式。对于较轻的病例，可优先选择隐形矫正器。若仅有单颗牙齿不齐，贴面也可作为一种治疗选择。

The applied treatment methods are:

  • Traditional Braces: Brackets and wires attached to the teeth apply continuous gentle force, gradually moving the teeth into the correct position over time.

  • Clear Aligners: Teeth are gradually aligned using invisible and removable clear aligners. This method is aesthetically more advantageous.

  • Lingual Orthodontics: A method where braces are placed on the inner side of the teeth, making them invisible from the outside.

  • 正颌外科手术：对于严重的颌骨畸形，除正畸治疗外，可能还需要进行外科手术干预。

Straightening Crooked Teeth at Home

Straightening crooked teeth at home is not possible. Using products that claim to straighten teeth is dangerous and can risk dental health. Therefore, using these devices sold online or resorting to home-based methods can seriously damage the tooth and jaw structure. For permanent and safe results, these types of treatments should only be performed by specialist orthodontists.
