Invisialigners trays are free from any kinds of wires and brackets. You can continue to work, eat, talk, and laugh like they are not even there.
Here are some points to justify their necessity:

Highly comfortable: They are manufactured with food-grade plastic, one that is highly comfortable to use and wear, unlike the ones that are metallic. There are no edges or ends that are sharp in these trays because these are customized for your denture.

Gives a boost to your fading smile: Teens, adults, or even seniors, who do not want others to judge them and even then, wear a great smile, can easily wear these trays instead of pesky braces or wires.

Great for reshaping crooked teeth: These aligners coax teeth, whether overbite or underbite, to move into a straight position. Hence, day by day, you can see improvement in your denture. At some point in time, these aligners will set all your uneven and crooked teeth right into one defined position.

Time-saving process for straightening your teeth: Compared to other solutions, these invisible trays are only needed to be maintained after approximately every six to seven weeks. Hence, you will visit the dentist less often as opposed to the visits required by other teeth straightening solutions.
