Los Angeles Invisalign practitioners are often faced with many questions from potential patients. Perhaps the most common is "how much does Invisalign cost?" Dentists and orthodontists can work with patients to figure out costs, which include factors such as your treatment goals. "How long does Invisalign take?" is another frequently asked question—generally 8–12 months. Those wondering "how does Invisalign work?" should speak with their doctor to get an overview of the clear aligners system, and patients wondering about the effectiveness of the treatment should ask to see Invisalign before and after photos.
