Orthodontics in the permanent tooth stage, when all deciduous teeth have been replaced, is another rapid growth period when the second and third big teeth erupt. Generally, 12 ~ 18 years old. At this time, the diagnosis of tooth deformity is relatively clear, and the correction is fast and stable in this rapid growth period.
If the above correction period has been missed, adult orthodontics can be performed after 18 years old to establish a good occlusal relationship, relieve crowded and disordered teeth, and thus prevent or treat periodontal disease and caries. At this time, orthodontics can adjust the axial direction of teeth to facilitate implantation or restoration, restore the functions of chewing, language and temporomandibular joint, and improve facial beauty. For severe deformity, orthognathic surgery can be performed, and the effect is very obvious.
Therefore, it is not absolute to determine the best time for orthodontics, and doctors will decide according to different types of tooth deformities and personal growth and development. However, for many patients with facial deformity caused by teeth, timely treatment can get twice the result with half the effort.
Wisdom tooth refers to the eighth tooth that erupted or hasn't erupted after 16 years old. Due to the smaller jaw size during the evolution of human beings, there is often not enough jaw space when wisdom teeth erupt, which often leads to the abnormal position and direction of wisdom teeth after eruption.
Wisdom tooth refers to the eighth tooth that erupted or hasn't erupted after 16 years old. Due to the smaller jaw size during the evolution of human beings, there is often not enough jaw space when wisdom teeth erupt, which often leads to the abnormal position and direction of wisdom teeth after eruption. Wisdom teeth not only have no chewing function, but also have a series of hazards or potential hazards.
First of all, due to incomplete eruption, the gum on the back is covered, and some of its crowns form a pericoronal pocket to store food and bacteria, which will lead to frequent inflammation of local soft tissues, unbearable pain, and even lead to limited mouth opening and difficulty in eating.
Secondly, most wisdom teeth are impacted forward, that is, they are supported on the second molar at an angle of about 45 degrees, and the two crowns form an included angle to block food. After a long time, the second molar became rotten until pulpitis became serious. Another consequence is that the inclined wisdom teeth continue to exert force on the second molar, causing it to form periodontitis and loosen the pain, so the second molar has to be pulled out, or the two teeth have to be pulled out, so the chewing function will be seriously damaged.
Third, although the eruption direction of some wisdom teeth is generally normal, the contact point with the second molar is abnormal, so that food is often embedded, and it is not easy to brush the gap here when brushing teeth, which may easily lead to caries of the second molar and shorten the life span.
According to statistics, 50% people have wisdom teeth, which erupt one after another at the age of 16. At this time, because the root of wisdom teeth has not been fully formed, it is easy to pull out and avoid the damage to the second molar, which is the best time to pull out wisdom teeth.
There are genetic factors in the emergence of buck teeth, but the most important reason is that with the evolution of human beings, food is getting finer and finer, dental arch is getting smaller and smaller, and dentition will be crowded. One of the manifestations is buck teeth.
In addition, bad oral habits, such as sucking your fingers and breathing with your mouth open, can also lead to buck teeth.
Cleft lip and palate may also lead to buck teeth. So remind everyone to pay more attention to it!
Then, as many netizens said above, it is more important to face it calmly, and the soul is the most important! ! I thought 50% people had wisdom teeth! Buck teeth! ! Don't be sad, be happy as soon as possible!
This is the first time I have answered a question. Very hard! Give me a good evaluation! I will try again!
I wonder if I can see it behind this line! ! ! ! In order to let the questioner see more detailed answers, I changed them four times! !
