15 06 InvisalignDescription: Invisalign uses a series of clear aligners that are custom-molded to fit one's mouth. The virtually invisible aligners gradually reposition your teeth.

How it's done: After an orthodontist or dentist evaluates and creates a program of treatment, photos and impressions of the teeth are taken. A CT scan is made from the impressions and produces a 3-D digital model of the teeth. Computer-aided design software is then used to stimulate the movement of the teeth during treatment. Stereolithography technology is used to build precise molds of your teeth at each stage of your treatment, out of which individualized, clear aligners are made. The patient wears each aligner for approximately two weeks for a period of six to 11 months.

Complications: Some patients may need a positioner or retainer to prevent their teeth from moving again.

Recovery: Temporary discomfort for a few days at the beginning of each new stage of treatment, which is typically described as a feeling of pressure. This discomfort typically goes away a couple of days after inserting a new aligner in the series.

Cost: $4,500 to $7,000.
