A. Orthodontics is a great way to have treatment my favoured method is invisalign which involves making see through removable mouthguards which move your teeth.  As they are removable you can take them out to eat and clean your teeth they are very comfortable.  Some people do not like having braces on the insides of there teeth thay are called lingual braces.  Pricing varies from dentist to dentist and the severity of your treatment.
I hope this helps
