Aligner attachments explained

If your orthodontist mentions "attachments" or "buttons," it can sound like a complication. It isn't. Attachments are a normal, often essential part of how aligners move teeth — here's what they are and how to live with them.

What attachments are

Attachments are small bumps of tooth-coloured dental bonding stuck to the surface of certain teeth. They're shaped and placed deliberately, and your aligners have matching dimples that grip them.

Think of them as handles. A smooth tray on a smooth tooth can struggle to make some movements — rotating a round tooth, or pushing one down or up. An attachment gives the aligner something to push or pull against, so those movements actually happen.

Why you might need them

Not every case uses them, but many do, especially for:

• Rotating teeth that are turned.
• Extruding or intruding — moving a tooth up or down in the gum.
• Holding a tooth still while others move around it.

How many you get depends entirely on your plan. Some people have a couple; others have a dozen.

Living with them

• They make trays tighter. That's the point — seating can take a firm push, and chewies help.
• They can be visible up close. They're tooth-coloured, but on front teeth a sharp eye may notice them. They come off at the end.
• Keep them clean. Food and stain can collect around the edges, so brush around each one and avoid staining drinks.
• Don't panic if one chips off. It happens; just tell your orthodontist so they can replace it. A missing attachment can stop that tooth tracking.

Attachments and tracking

Because attachments are doing real work, a tray that won't fully seat over them is a sign your teeth may be falling behind. Consistent wear matters even more with attachments — here's the daily target, and the change schedule calculator helps you keep every switch on time.

General guidance, not medical advice. Your orthodontist decides if and where attachments are needed.
