Many people have teeth which are crooked or crowded. Orthodontics is the straightening and realignment of teeth to correct these irregularities. This aims to enhance their appearance and create a sense of aesthetic harmony.
Believe it or not your teeth are always moving, albeit minutely. Clearstep exerts gentle pressure upon the tooth/teeth in the direction in which you'd like them to move.
As with many orthodontic treatments, K positioners may temporarily affect your speech, and you may have slight lisp for a day or two. However, as your tongue adjusts to the presence of the K positioners, any lisp or minor speech impediment caused by the device should disappear, usually fairly early on in the treatment.
