Orthodontic treatments, including Invisalign, may cause minor changes in speech patterns, but any adjustments needed are typically quick and straightforward. It's worth noting that traditional metal braces can sometimes lead to speech difficulties, but they can be addressed with proper care and attention from your orthodontist. Conversely, Invisalign is virtually invisible and doesn't have the same potential for speech difficulties as metal braces, making it a popular choice among patients. Of course, each patient's needs are unique, so it's always best to consult your orthodontist to determine which treatment is best for you.
