What causes crooked teeth?

Some people always smile without showing their teeth, not because they are shy, but because their teeth are crooked and become sunken when they smile. A good set of teeth can make you feel confident and smile without any scruples. Uneven, crowded or protruding teeth can cause overall facial disharmony and give the face an aged look at a young age. Then why do some people have neat and beautiful teeth, while others are afraid to smile? The editor will answer for you below.

Congenital factors: refers to the various influences on the fetus during its growth and development in the mother's womb, which may be nutritional metabolic disorders of the mother or fetus, the mother's rubella or viral infection, trauma to the mother during pregnancy, or birth injuries caused during delivery.

Acquired factors: mainly refers to the influence on the growth and development process after birth, mainly including the following 7 aspects:

(1) Early loss of deciduous teeth: insufficient space will occur, resulting in crowding and misalignment. The eruption guiding function is lost, and the permanent teeth become misplaced or fail to erupt.

(2) Bad habits: Most of them are finger sucking habits, tongue habits, lip biting habits, object biting habits, jaw protrusion habits, bad swallowing habits, unilateral chewing habits, etc., which can cause various malocclusions.

(3) Supernumerary teeth: Supernumerary teeth can cause morphological and kinetic disorders in the tooth and jaw system. Supernumerary teeth between central incisors can lead to the formation of central incisor gaps, etc.

(4) Congenital missing teeth: mostly due to developmental and embryonic reasons. The missing third molars are mostly due to germline degeneration.

(5) Retained deciduous teeth: When individual teeth do not fall out within the prescribed time limit, they are called retained deciduous teeth. This may result in the eruption of the successor permanent teeth being blocked and becoming buried, or the permanent teeth erupting out of the same position.

(6) Insufficient wear of deciduous canines: Because children eat soft food, some deciduous canines are not worn as much as other teeth, and thus they are higher than the tooth surface of the dental arch, resulting in premature contact, causing forward or lateral movement, and forming crossbite.

Crooked teeth not only affect the appearance, but also the health of dental tissue, and may cause bad breath and bleeding gums. Regularly arranged teeth are self-cleaning, but irregularly arranged teeth make brushing and cleaning difficult. Therefore, if your teeth are crooked, the editor recommends that you get orthodontic treatment to avoid oral problems.
