Invisalign Bent: Why This Happens, How To Fix

You have to wear Invisalign for a long time and face various issues during this time. One of these problems is Invisalign gets bent.

In this article, I’ll discuss why Invisalign becomes bent and how to fix it.

Can Invisalign bend?

Sometimes Invisalign can become bent due to improper handling or lack of care for the aligners. It can be both unsightly and uncomfortable. However, it doesn’t happen often and is usually not a big deal.

Why does Invisalign bend?

There are a few reasons why Invisalign can become bent.

1. The material they made of

The most common reason is that the aligners are made of soft material to give you comfort while wearing them. However, this means that they can get bent if they’re not handled carefully.

2. Not handling them properly

Invisalign should be handled with care. If you’re not careful with them, they can become bent.

For example, if you drop them or put them in your pocket, they can become bent.

3. Defective Invisalign trays

Another reason why Invisalign can become bent is because of the way they’re made.

Sometime, you may get a defective aligner. This is because the aligners are created using a 3D printing process, which can sometimes cause them to warp.

4. Wearing them for too long

Another reason why Invisalign can become bent is that you’re wearing them for too long.

Invisalign is meant to be worn for 20-22 hours a day. If you wear them for more than that, they can become bent.

5. Biting the trays in place

If you bite down on your Invisalign aligners in place, this can cause them to become bent.

Biting on the trays in place puts pressure on them and can cause them to warp out of shape.

6. Poor inserting technique

If you don’t put your Invisalign incorrectly, this might also cause the aligners to become bent.

This is because when you don’t know how to insert the aligners correctly in your mouth, you may end up putting pressure on them.

7. Wrong removal technique

The final reason why Invisalign can become bent is that you’re removing them incorrectly.

This can happen when you remove your Invisalign aligners with force instead of pushing them out from the back of your mouth gently.

8. No taking care of the aligners

Invisalign can also become bent if you don’t clean them properly. If you don’t brush your teeth regularly or if you don’t remove the aligners when you eat, they can start to collect plaque and bacteria. This can cause them to bend out of shape.

9. Poor storage

If you don’t store your Invisalign aligners properly like storing them in a case, this can also cause this problem.

10. Chewing gum with Invisalign in

If you chew gum with Invisalign in, Invisalign can get bent.

When you chew gum, you’re putting pressure on the aligners. This may lead them to become misshapen and distorted.

11. Not using aligner removal tools

If you try to remove your Invisalign aligners without using the proper tools, this can cause them to become folded or bent.

The aligner removal tools are designed to help you remove your aligners without damaging them.
