What Are Dental Attachments and How Do They Help Aligner Treatment?

On your way to get straight teeth, you possibly read about dental attachments, or maybe even heard your orthodontist mention them during the consultation. In this article, we would like to explain the purpose of dental attachments, and how they can be useful for the teeth straightening process.

The brief and non-technical description of dental attachments is the following: "small bumps that are placed on separated teeth, to give the aligner a proper 'leverage’ to achieve difficult teeth movements".

When orthodontic aligners appeared, they were able to perform a varied range of teeth rotation and other movements. But over time, orthodontists found out that they had difficulties rotating cone-shaped teeth, as these ones often do not have an active surface that can be used to generate teeth movements.

So, it was clear that conical teeth needed a different approach, that would provide the leverage over the cone-shaped teeth to generate enough force to make the teeth movements happen. That's when dental attachments were developed.


Attachments are made from a composite material and come in many different shapes and sizes. They provide the surface against which aligners can push to rotate the teeth as planned.

Attachments are custom made for each individual orthodontic treatment and used nowadays not only to move conical teeth, but also for teeth uprighting, keeping roots parallel and a lot more.

Usually dental attachments are barely visible and worn only during specific stages of the teeth straightening process. You can check some of eon Aligner before/after images from our patients, who had attachments to achieve difficult rotations during their orthodontic treatment.
