I think the risk of dental decay is another factor. If I am not wrong, you have to keep the traditional dental braces in place without ever taking them off for the entire duration of the n months / year? Not being able to take them out and brush / otherwise clean the tooth under them is apparently a cause for dental decay when using traditional braces.
