Invisalign attachments, also known as Invisalign SmartForce attachments, are tiny pieces of dental bonding material that Dr. Gellerman attaches to the front of your teeth. The attachments are nearly invisible since they’re the same shade as your natural teeth. The attachments act like small handles, giving your Invisalign aligners the traction they need to shift your teeth in an ideal way. Although not everyone needs attachments, they’re very beneficial for patients who need moderate to major teeth shifting. With Invisalign attachments, you can straighten your teeth invisibly, even if you have complex orthodontic needs.
