Deviated incisor is a state in which the two incisors grow crooked relative to the arch and to the adjacent teeth. The front teeth are the most noticeable part of the teeth, so when they are misaligned, they will greatly affect the aesthetics of the smile as well as the face. The misaligned incisors can be single or multiple teeth.Types of common deviated incisors in clinical practice:
V-shaped deviated incisors: two incisors grow out of alignment with other teeth, the inner edge of the contact between the two teeth forms an acute angle like the letter V. The incisors grow at an angle: they are also misaligned, but the teeth are not in a standing position, but tilted, they can be on the same side or opposite each other. The incisors are misaligned and uneven: it can be one main incisor that is protruding outward or inward, or both lateral incisors erupting inward, or one tooth is protruding with one erupting tooth. drooping in... Causes of misaligned incisors:
Due to innate position of the teeth are arranged in the wrong position leading to misalignment. The front teeth are pinched, pushed by other teeth, so they are out of position out of the dental arch. Due to diseases that cause early tooth loss such as crooked teeth, loss of molars or other teeth, leading to the creation of a gap on the dental arch, the teeth are displaced to fill the gap, leading to misalignment. Due to the habit of sucking fingers, holding a pacifier for a long time, sticking your tongue out or leaning against the front teeth... Orthodontic methods with misaligned front teeth:

Braces combined with orthodontics: takes more time than the other method, but after braces, teeth are naturally beautiful and in better position, the maintenance effect is permanent. For severe cases of misalignment, which cannot be used with porcelain veneers or braces, it is required to have orthodontic surgery, or tooth extraction that cannot be handled.

4. Wisdom teeth are misaligned
Wisdom teeth can grow in the upper jaw, lower jaw or both, but most often wisdom teeth grow out of the lower jaw.The main types of wisdom teeth deviation:
Proximal deviated teeth: the crown of the tooth is towards the 7th tooth. In this case, food is easily trapped between the 2 teeth causing tooth decay, sometimes the tooth decay spreads to the 7th tooth. , at the same time also cause pushing teeth. In some cases, inflammation can cause swelling and pain. Wisdom teeth grow far apart: in contrast to the situation of proximal deviation, the crown of the tooth is directed away, and the root of the 8th tooth is pushed into the root of the 7th tooth, causing severe pain at the root, which can lead to weakness in the long run. root of tooth 7. In severe cases, both teeth 7 and 8 will have to be extracted. Teeth erupt in the cheek area: the tip of the tooth is facing the cheek area, so when eating, it is easy to bite on the cheek causing damage, the cheek heat is repeated many times. Teeth erupting 90 degrees: is a situation where wisdom teeth grow horizontally. This is a common case in misaligned wisdom teeth, not only affecting tooth number 7 causing bone loss, inflammation or root cysts, but also can cause jaw dislocation.. Causes of wisdom teeth eruption Deviation :
Because wisdom teeth grow too late: usually wisdom teeth usually erupt at the age of 18-25 years. In late-growing people, when the teeth are almost completely stable in the arrangement of the teeth, wisdom teeth will have little or even no space to emerge, leading to misalignment. Because wisdom teeth erupt at the wrong time when the jaw structure is stable, the position of the teeth on the dental arch has also been fixed, so the wisdom teeth do not have enough position to stand, causing crowding and pushing of the adjacent teeth. edge. Wisdom teeth erupt when the gums are stable. Gums are an important part directly related to the eruption of wisdom teeth as well as other teeth. In adulthood, the gums are firm, densely covered with dental arches, hindering the development of wisdom teeth, slower growth time and can affect other teeth. Solutions to handle when wisdom teeth are misaligned:
For mild cases:
Use antibiotics, pain relievers and anti-inflammatory. Apply warmth on the outside of the cheek to the treatment area. Note cleaning the mouth area, gargling with physiological saline when having symptoms of toothache. For severe and moderate cases:
Go to a doctor for advice on antibiotics, anti-inflammatory drugs to reduce edema combined with surgery or tooth extraction if the pain is severe, affecting other functions.
5. Tooth number 7 is misaligned

The pattern of deviation of tooth number 7 is similar to that of tooth number 8. Tooth number 7 can also grow sideways 90 degrees, or grow slightly at angles less than 45 degrees. Teeth can grow back in or out, can also erupt into tooth 6.
Usually in cases where tooth number 7 is misaligned, there will be indications for tooth extraction. However, tooth number 7 along with tooth number 6 play an important role in the function of chewing and grinding food. If tooth number 7 is extracted, it will lead to tooth loss, not only affecting chewing function but also creating conditions for other teeth to be pushed. On the other hand, in the 7th tooth region, there are also many nerves involved, so when specifying tooth extraction, you must be very careful and consider carefully before specifying extraction.
