Everyone wants a perfect smile. Aside from looking pretty great, a set of healthy, aligned teeth allows you to chew and speak properly and makes practicing proper oral hygiene a lot easier. According to the American Association of Orthodontics, an estimated 4.5 million Americans, most of them children and teenagers, wear braces on their teeth to correct alignment issues. With the introduction of Invisalign and clear aligners, adults and older teenagers can also have their teeth straightened discreetly. Did you know that once you’re done with your Invisalign you will have to wear either a permanent or removable retainer?
