Invisalign^® corrects the same dental problems as traditional metal braces; the only difference is that Invisalign^® trays are almost invisible to the naked eye, and can be removed at will.
Here are some problems that are commonly corrected with Invisalign^®:

Large gaps between teeth– This can sometimes occur because teeth are missing or because the jaw continues to grow abnormally.

Crossbite– This common dental problem occurs when one or multiple upper teeth bite inside the lower teeth.  As a consequence, uneven wear can lead to bone erosion and gum disease.

Overbite– This problem occurs when the upper teeth project further than, or completely cover, the lower teeth.  Eventually, jaw pain and TMJ may occur.

Underbite– This is the inverse of the overbite; the lower teeth project further than, or completely cover, the upper teeth.  Eventually, jaw pain and TMJ can occur.

Traditional dental braces, Invisalign^® aligning trays, and dental veneers are three different ways to perfect the alignment of the teeth. There are many different considerations to make when deciding which treatment will be best, and each of these options works better in certain situations. 

Invisalign^® differs from traditional braces in that the aligning trays are fully removable.  This means that more discipline and commitment is required from the patient.  This is not usually a problem since the trays are comfortable and nearly invisible. Almost identical results can be obtained by using either treatment.

Invisalign^® is preferable to veneers in many cases because unlike veneers, Invisalign^® actually straightens the teeth. Veneers are thin covers that the dentist permanently affixes to the teeth. Teeth must be etched beforehand, meaning that to remove dental veneers, an alternative covering must be constructed. In addition to being somewhat expensive, veneers can break and often last for less than 20 years.

First, the dentist needs to devise an initial treatment plan before creating the special aligning trays.  Three-dimensional digital images are taken of the entire jaw.  These images allow the dentist to move specific teeth on the screen, view the jaw from different angles, and also foresee what the face might look like in years to come.  In essence, this technology can show how Invisalign^® trays will change the facial aesthetics.

Once planning is complete, a unique set of aligners is made. The total number of aligners required varies with each individual case, but 20-29 sets per arch is typical.

Life with Invisalign^® aligning trays may take several weeks to get used to. The trays should be worn constantly, except when eating and drinking. It is important to remove the trays when consuming food or drink because food can become trapped between the tray and the teeth, causing tooth decay.

Usually, new trays are necessary every two weeks, and progress between appointments can be seen with the naked eye. There is no doubt that Invisalign^® aligning trays have revolutionized orthodontics. Invisalign^® is renowned for being both comfortable and effective.
