Minor irregularity (minor crowding) of the teeth can be corrected with a series of clear plastic aligners, each one applying gentle force to move the teeth into alignment. Depending on the degree of irregularity, 3 to 50 pieces of aligners may be required. Clear aligners can be removed for eating and cleaning, so they are very hygienic and unlikely to cause tooth decay. They adapt closely to the anatomy of your teeth and gums; they are very comfortable and do not affect your speech. They are barely visible to the casual observer; your office colleagues wouldn’t even know you are wearing them.
