Does orthodontics require tooth extraction?

As we all know, teeth are not only important helpers for people to eat and talk, but also directly affect people's appearance. However, some people suffer from orthodontic problems due to congenital or acquired factors. In this case, is it better to keep the teeth or extract them? Regarding this issue, we need to analyze the specific problem specifically. Below we will introduce in detail whether teeth need to be extracted for orthodontic treatment.

Three types of people need to have their teeth extracted

1. Crowded dentition

Because the number of teeth is greater than the number of bones, tooth deformities occur. Therefore, orthodontic treatment can use the space created after tooth extraction to realign crowded teeth, thereby coordinating the relationship between the number of teeth and the number of bones and reducing the recurrence of deformities.

2. Protruding teeth

For people whose front teeth protrude too much, a certain number of teeth need to be extracted to create space, so as to achieve the purpose of retracting the front teeth and moving the back teeth forward, alleviating facial protrusion and making the customer's facial profile more beautiful.

3. Correction of abnormal occlusal relationship

For those with abnormal tooth occlusion, the occlusion relationship of the upper and lower teeth can be adjusted through tooth extraction orthodontic treatment. The extraction gap adjusts the occlusal relationship of the posterior teeth so that the cusps of the posterior teeth are staggered, the occlusal contact area is maximized, and the best chewing efficiency is achieved.

Is tooth extraction harmful to health? Correct tooth extraction is good for your health

Expert's answer: Tooth extraction treatment is to coordinate the inconsistency between tooth volume and bone volume. In the absence of obvious bony imbalance between the upper and lower jaws, the most fundamental reason for the occurrence of malocclusion is that the space in the alveolar bone is insufficient to accommodate all existing teeth. Tooth extraction treatment can not only better match the tooth volume with the bone volume, but also make the treatment results more stable. Moreover, the facial features of Orientals are that their noses are not straight enough, their lips are more protruding, and their chins are not as well developed as those of Westerners. In order to achieve a better facial shape, about 60% of patients need tooth extraction and correction. Therefore, as long as you go to the orthodontic department of a regular hospital, tooth extraction is a very common and mature treatment method, and tooth extraction will not harm the patient's function and health. After orthodontic treatment, the teeth will be aligned neatly, the occlusion will be normal, and the oral system will be healthier.

Does tooth extraction make teeth loose faster? Periodontal disease is the main cause of loose teeth

Expert answer: The main reason for loose and falling teeth is periodontal disease. Because the oral environment is not maintained well, the plaque around the teeth caused by eating is not cleaned in time, and thus further reacts with the minerals in the saliva to form tartar, which slowly accumulates over time and infects the surrounding tissues, causing periodontitis. The tissues supporting the teeth, such as the alveolar bone, will be absorbed due to periodontitis. As the alveolar bone is absorbed, the area of ​​the tooth root surrounded by the alveolar bone will gradually decrease, eventually causing it to loosen and fall off. "It is undeniable that the teeth will become more loose during the correction process due to stress and alveolar bone remodeling, but when the orthodontic treatment is over and the teeth are no longer under stress, they will recover on their own. As long as the oral environment is well maintained and periodontitis is avoided, there will be no problem of loose teeth falling out in the future."

Which teeth can be extracted?

The first pair of fangs!

Experts say that teeth should be extracted during orthodontic treatment. The first teeth to be affected are the first pair of canines, which are the first teeth after the canines (commonly known as tiger teeth). He said that because the first bicuspids are located at the special geographical location where the anterior and posterior teeth meet, the space left after extraction can be easily used to relieve the crowding of the anterior teeth or to retract the protruding anterior teeth, while at the same time being able to coexist harmoniously with the adjacent teeth.

Five types of people cannot have their teeth extracted

Here I would like to remind all netizens that some people are not suitable for orthodontic treatment, let alone orthodontic tooth extraction. People who are not suitable for orthodontic surgery mainly include: 1. Patients with systemic diseases, such as hyperthyroidism, diabetes, tuberculosis, mental illness, etc.; 2. People with severe malnutrition; 3. Pregnant women; 4. Patients with periodontal disease; 5. Patients with poor oral hygiene habits or prone to dental caries. They are not suitable for orthodontic surgery before their periodontal disease and oral hygiene are well controlled.
