Ms. Schölgens, the consumer centers of North Rhine-Westphalia and Rhineland-Palatinate took a close look at aligner providers in 2021. Aligners are clear plastic splints that can be used to treat slight misaligned teeth. What triggered it? We noticed that the providers ran a lot of advertising and worked with influencers on social media. A large, well-known provider – “Dr. Smile” – advertised with the slogan “Your perfect smile” – a statement that promises a very good treatment success. We have looked at the advertising of the providers and analyzed the information on the websites.
