Invisalign is the brand name of a type of thin clear aligner used in orthodontic treatment. The aligner is made from a flexible thermoplastic material named SmartTrack.

As the name suggests, this product is designed to make orthodontic treatment “less conspicuous,”

Although Invisalign aligners may not be completely invisible, these clear coverings fit tightly over your teeth and are much less noticeable than the brackets and wires of tradition braces Invisalign can be used for a variety of purposes, including crowding and spacing issues, as well as some mild and moderate bite issues.

What’s involved with wearing them?

The first step in the process involves a visit with the dentist, who will create a 3-D image of your mouth and jaw. They’ll use this image to put together a plan for moving your teeth into their proper place. You can then book in for a scan and see your final smile straight away.

Your dentist will then use that plan to create a series of customized plastic aligners. These aligners will apply pressure to your teeth, gradually shifting them and moving them into the desired places.

Depending on your instructions, you’ll switch out one set of aligners for a new set about once every week or two. Typically, you’ll need to wear the aligners for 20 to 22 hours a day.

Cons :

Requires compliance. To get the maximum benefit from Invisalign, you must wear the aligners for 20 to 22 hours a day. If you think you’ll be tempted to slip them out more often, it may not be the best choice for you.

Removal when eating or drinking. When you’re eating or drinking, you need to take the aligners out. If you don’t, food or drink can get into them. This causes bacteria to grow along your teeth or gumline, which could lead to cavities. Also, liquid can seep down into them and cause staining of the aligners and your teeth.

Food limitations. You may experience tooth soreness when the aligner is removed, which can limit your food choices. Hard foods, especially, should be avoided.
