Invisible braces can usually be seen in three months, six months or more there will be obvious changes. 1. The effect of invisible braces varies from person to person and is related to the patient’s age, the degree of malocclusion of the teeth themselves, and the time the individual wears the invisible braces. People who have good compliance to wear invisible braces on time and are able to maintain the length of time every day have better results. 2. Teenagers between the ages of twelve and sixteen have better results because the roots of their teeth are not yet fully stabilized, and if the teeth themselves have a lesser degree of malocclusion, there will generally be noticeable changes in about three months. For older adults with more severe malocclusion, or who do not wear them long enough, the results are poorer and it may take more than six months to see noticeable changes. So for teenagers with less severe malocclusion wearing invisible braces can see obvious changes in three months, while serious ones need more than six months.
