Invisalign Attachments Explained — What Are Those Bumps?
If you are researching Invisalign treatment in Blacktown, you have likely seen the marketing images of perfectly smooth, clear aligners. However, when you start your treatment, you might be surprised to learn that you need “attachments” placed on your teeth.
Many patients ask, “What are these little bumps, and why do I need them?” At Your Family Dentist, we believe in ensuring our patients are fully informed about every aspect of their treatment. In this guide, we explain exactly what Invisalign attachments are, how they work, and why they are the secret weapon behind complex smile transformations.
What Are Invisalign Attachments?
Invisalign attachments (sometimes called “buttons”) are tiny, tooth-coloured dots of dental composite resin. This is the exact same safe, durable material we use for standard white fillings and composite veneers.
These attachments are temporarily bonded to specific teeth at the beginning of your Invisalign treatment. They are custom-shaped—they can be rectangular, square, or triangular—depending on the specific movement required for that tooth.
When you place your clear aligner over your teeth, the plastic tray fits snugly around these attachments.
Why Are Attachments Necessary?
To understand why attachments are needed, you have to understand the limitations of smooth plastic.
Clear aligners work by applying gentle pressure to the teeth. For simple movements, like pushing a tooth slightly backward or forward, the smooth plastic tray is perfectly capable of doing the job on its own.
However, teeth are naturally smooth and often rounded. If a tooth needs a complex movement—such as being rotated, pulled downward (extruded), or pushed upward (intruded)—the smooth plastic aligner will simply slip off the tooth, much like a wet hand trying to turn a smooth doorknob.
This is where attachments come in. They act as tiny handles or anchors. They give the aligner something to grip onto, allowing the plastic tray to apply directional force to the tooth. Without attachments, Invisalign would only be able to fix very minor cosmetic issues. With attachments, Invisalign can achieve the same complex orthodontic movements as traditional metal braces.
What to Expect: The Attachment Process
Having attachments placed is a quick, completely painless process that does not require any drilling or anaesthetic.
- Preparation: We clean the specific teeth and apply a mild conditioning gel to slightly roughen the microscopic surface of the enamel, ensuring a strong bond.
- Placement: We use a special template (which looks like an aligner) that has small gaps where the attachments should go. We fill these gaps with the tooth-coloured composite resin.
- Curing: We place the template over your teeth and use a high-intensity blue light to instantly harden the resin.
- Removal: We remove the template, leaving the tiny attachments securely bonded to your teeth. We then polish away any excess resin.
When your treatment is complete, we simply polish the attachments off. It takes just a few minutes, and your natural tooth enamel underneath is completely unharmed.
Common Questions About Attachments
Are they noticeable?
Because we carefully match the composite resin to the exact shade of your natural teeth, the attachments blend in very well. When you are wearing your aligners, the plastic covering the attachments makes them slightly more visible, but they are still far less noticeable than metal or ceramic braces.
Do they hurt?
The placement and removal process is completely painless. When you first get them, they may feel slightly rough against the inside of your lips or cheeks when your aligners are out, but you will get used to the feeling within a few days.
Will I need them on every tooth?
No. Attachments are only placed on the specific teeth that require complex movements. The ClinCheck® 3D software determines exactly which teeth need attachments to achieve your final smile design.
Do they stain?
The composite resin can stain over time if you consume a lot of coffee, tea, red wine, or highly pigmented foods like turmeric. To keep them looking invisible, maintain excellent oral hygiene and brush your teeth after eating before putting your aligners back in.
