Why is tooth extraction necessary for orthodontics?

Orthodontics is when the doctor applies an external force to the teeth through the appliance, so that the alveolar bone is remodeled and the teeth move. However, the amount of teeth in the oral cavity of many people is greater than the amount of bones, and the width of the teeth is greater than the circumference of the jaw, resulting in the appearance of teeth. Problems such as crowding and misalignment.

The purpose of tooth extraction is to get enough space to bring the misplaced teeth back into a neat position, or to retract the protruding teeth to improve the profile and adjust the bite.

Therefore, after orthodontic tooth extraction, it does not mean that you just leave the hole there and you are done. Instead, use the reconstruction function of the alveolar bone, and apply appropriate orthodontic force to move the teeth in the bone, slowly occupy the tooth extraction space, and align the teeth.

Whether to extract teeth is mainly judged according to the individual's tooth condition, and the doctor's treatment method and technology should also be considered. The purpose of orthodontics is to improve functionality and aesthetics. If you can find space to arrange the teeth without affecting the two Neat, there is no need to extract teeth. Conversely, if you insist on not extracting teeth for correction, the effect may be poor, and it is easy to relapse after orthodontic treatment, and you may miss the right time for treatment.

The principle of tooth extraction and correction: try not to extract teeth, if you want to extract, first extract bad teeth (loose teeth, tooth decay, teeth with poor shape), and then extract teeth with relatively secondary functions. When extracting teeth, it is generally symmetrical up, down, left, and right, and 4 teeth are extracted. Basically, front teeth, first and second permanent molars and canines will not be extracted to ensure aesthetics and function.

Tooth extraction is usually required if any of the following 3 conditions occur

1. Crowded teeth. Because the amount of teeth does not match the amount of bone, the teeth are crowded, so a certain number of teeth must be extracted during orthodontics.

2. Facial protrusion, that is, buck teeth, needs to extract a certain number of teeth to obtain gaps, achieve the purpose of retracting the front teeth, improve the protrusion of the dental arch, and relieve facial protrusion, so that the patient's facial profile is more beautiful .

3. The occlusal relationship needs to be corrected. Due to the abnormal occlusal relationship of the upper and lower teeth, these patients need to use the tooth extraction gap to adjust the occlusal relationship of the upper and lower posterior teeth, so that the upper and lower posterior cusps are staggered, and the occlusal contact area is large to achieve good chewing efficiency.

It is common to extract teeth before orthodontic treatment. Don’t think one-sidedly that the doctor did it on purpose. In fact, there is probably no one in this world who loves teeth more than dentists. The reason why tooth extraction is recommended for better orthodontic effect Otherwise, keeping those teeth would be a burden.
