The frenetic pursuit of a perfect smile has triggered an over-heated market where the number of professional orthodontists is far from enough. The number of clinical orthodontic cases almost doubled from1.6 million in 2015 to 3.1 million in 2020 and the figure is expected to rise to 9.5 million in 2030. Compared to the growing demand, the country’s 6,100 recognized orthodontists are insufficient to satisfy the market, leaving a great gap that is being tapped by retainer producers and dental clinics. But without properly trained professionals, many clinics and online producers are bringing more trouble than beauty to dental patients. Because of unscrupulous operations, many customers find their costly tooth correction only worsens their oral condition and forces them to seek corrective treatment in dental hospitals. Some companies also target children aged 3-5, who should not be undergoing orthodontic treatments.
