Invisalign Attachments: A Guide to the Small Bumps on Your Teeth
During your Invisalign consultation in NYC, your orthodontist likely mentioned "attachments." Far from being a complication, these small, tooth-colored bumps are one of the most important innovations behind the treatment's success. They enable complex tooth movements and are key to achieving a perfect, predictable result.
What Exactly Are Invisalign Attachments?
An attachment is a small dot of dental composite resin (the same durable material used for tooth-colored fillings) that is temporarily bonded onto specific teeth. They are a core component of Invisalign's patented SmartForce® technology. Each attachment is precisely shaped and sized (rectangles, squares, ovals) and oriented to achieve a specific, complex movement for that individual tooth.
What is the Purpose of Attachments?
Attachments act as tiny handles or anchor points. They give the aligner a surface to grip, allowing it to apply the right amount of leverage and force in the right direction. Without them, the smooth, curved surface of a tooth wouldn't allow for the complex movements needed in most orthodontic cases.
Their role is essential for:
- Difficult Rotations: Turning a severely rotated tooth into the correct position.
- Extrusion and Intrusion: Moving a tooth down (out of the gum) or up (into the gum).
- Root Control: Ensuring the tooth's root moves with the crown for a stable, healthy result.
- Anchorage: Holding certain teeth firmly in place while others are moved around them.
How Are Attachments Placed?
The placement of attachments is a simple, quick, and completely painless procedure performed by your orthodontist.
- The tooth surface is cleaned and prepared to ensure a strong bond.
- A clear template, precisely matching the location of the attachments, is placed over your teeth.
- Your orthodontist fills the template's reservoirs with the liquid composite resin.
- A special blue curing light is used to harden the composite in seconds.
- The template is removed, leaving the small, solid attachments perfectly bonded to your teeth.
Frequently Asked Questions About Attachments
Are They Visible?
Attachments are designed for maximum discretion. They are matched to the exact shade of your tooth enamel. When your aligners are on, they are very difficult to see. When the aligners are off, they may be slightly visible up close, but they remain far less noticeable than any component of traditional braces.
Will They Stain?
The composite material itself is non-porous and highly resistant to staining. However, it's important to maintain excellent oral hygiene, as the bonding agent around the very edge of an attachment could potentially stain from frequent consumption of coffee, tea, or red wine. Brushing after meals will prevent this.
Is It Hard to Eat with Them?
You will always remove your aligners to eat. The attachments remain on your teeth. You may find that food can sometimes get caught around them, but a quick rinse with water or brushing after your meal before putting your aligners back in easily solves this.
What Should I Do if an Attachment Falls Off?
It's uncommon, but it can happen. Don't panic—it is not an emergency. Continue wearing your current aligner and call your orthodontist's office to let them know. They will schedule a quick visit to rebond it. It's important to have it replaced to ensure your treatment stays on track.
When and How Are Attachments Removed?
Attachments are removed at the very end of your treatment, before you get your final retainers. Your orthodontist uses a special tool to gently buff the composite off the tooth surface, which is then polished smooth. The process is fast, painless, and does not harm your tooth enamel in any way.
Conclusion: A Major Asset for a Perfect Smile
Invisalign attachments should be viewed as a sign of a highly customized and powerful treatment plan. They are a technological advantage that allows Invisalign to achieve world-class results. It is largely thanks to these SmartForce® features that Invisalign can now effectively treat an ever-expanding range of complex teeth straightening cases.
