Invisalign is a method of straightening crooked teeth without visible braces.

I have considerably big gaps in both frontal upper and lower teeth. If I use Invisalign, how long will my treatment last?

For most Invisalign patients, treatment can last anywhere from nine to eighteen months. Of course, treatment time depends on your specific needs. Although the Invisalign aligners are removable, wearing your aligners as much as possible, ideally for at least 22 hours each day, will allow you to see the result of a beautiful smile faster.

We recommend that you see an orthodontist as she will be able to give you a more precise answer. However, you should expect to wear the Invisalign aligners for about two years. The orthodontist can also determine if you are a candidate for Invisalign.

Most Invisalign cases average one year in length. That being said, it will be important for you to have a consultation to determine why the gaps are there. Sometimes gaps are caused by what's called a "tooth size discrepancy," meaning the size and width of tooth that developed is insufficient for the width of your jaw. This can mean that you may need bonding or veneers instead of Invisalign treatment.

The treatment can last from a year up to 5 years depends on how much movement is needed.

Every case is different. Invisalign is a set of aligners, each aligner is designed to move teeth about 1/4 of a mm. You have to wear each aligner for two weeks. So, the number of aligners would be determined based on the severity of the case. It would be best to see a dentist to determine if gap closure is even possible with invisalign. It might require additional treatments.

Unfortunately, without more information, I can't tell how long the Invisalign treatment might last. Invisalign is an excellent solution to close gaps. Sorry I can't be more informative. Les Latner, DDS
