You can straighten only one row of teeth, but doctors generally do not recommend this operation.

Because the degree of dental deformity varies from person to person, many people have great doubts about whether orthodontics can correct only half of the mouth. From the perspective of professional orthodontic treatment, only half-mouth orthodontics can easily lead to misalignment of the upper and lower teeth, leading to orthodontic failure.

Extended information:

The dangers of correcting only a single row of teeth:

1. Affecting the chewing function of teeth: If only the upper jaw is corrected and the lower jaw is not corrected, the upper jaw will not be corrected. All teeth involved in correction will move to some extent after alignment, but the uncorrected teeth in the lower jaw will not move, resulting in a change in the bite. When only partial correction is done, the occlusal relationship between the upper and lower jaw cannot be corrected manually. Therefore, the bite will become worse after correction, which will affect the most basic function of teeth - chewing, thus affecting the digestive mechanism.

2. Loose teeth and fall out: Teeth can easily form bite trauma, causing teeth to loosen and fall out.

3. Cause facial soft tissue problems: Occlusal balance imbalance can cause facial soft tissue problems, such as muscle problems, facial stiffness, and reduced facial softness.

4. Lead to oral diseases: Occlusal balance imbalance can lead to periodontal disease, pain in the temporomandibular joint area, and even unexplained headaches, wedge-shaped defects of most back teeth, etc.

5. Unstable and easy to relapse: Imbalance of occlusal balance will lead to unstable tooth arrangement. Over time, the dentition will gradually relapse and become uneven again.
