Are the dozens-of-yuan orthodontic braces sold online effective?

Generally speaking, the dozens-of-yuan orthodontic aligners available online are produced and sold through unofficial channels. Their quality cannot be guaranteed. Although they may have some effect, using these aligners involves many risks and problems. The specific analysis is as follows:

Low-cost aligners purchased online may provide a certain degree of tooth stabilization to varying extents, but they are typically one-size-fits-all products that cannot be customized according to individual dental conditions. Since everyone's teeth alignment differs, using a generic aligner may result in poor fit and could even lead to dental problems. Moreover, these online-purchased aligners have not undergone rigorous testing or certification, so their material safety and quality cannot be assured. Some may contain harmful substances that can damage both oral health and overall well-being.

In addition, there is no professional medical guidance or monitoring when using online-purchased aligners, making it easy to misuse them. For example, the duration, method, and force applied during aligner use must be adjusted and supervised based on individual conditions; otherwise, existing dental issues may worsen or other health complications may arise. Therefore, although low-cost online aligners may offer some benefits, their drawbacks significantly outweigh the advantages, and their use is not recommended.

If you need orthodontic treatment, it is recommended to visit a正规 hospital or qualified dental clinic.
