Periodontal disease is a common oral health issue — and especially so later in life. According to the CDC, nearly 50% of adults aged 30 and older suffer from some form of periodontal disease, and that figure increases to 70% in adults older than 65. However, aligners are not a direct cause of this issue.
You still might be under the misguided impression that clear aligners require less hygienic maintenance than braces, as they are less susceptible to getting food debris caught in them. But that couldn’t be any further from the truth! Though less food debris is caught in aligners, aligners still form a barrier that minimizes saliva contacting the gums and teeth.
