The attachments serve as anchors for your trays so they can fit snuggly and deliver the correct amount of pressure to shift your teeth and jaw into place. The attachments are made from composite resin, just like the fillings used in teeth, and they are chosen carefully to match your teeth' natural color. Not all of your teeth will need attachments, and Dr. Thawani will only place them on your front teeth if necessary. They are designed to blend in discreetly, but they may be noticeable if someone is looking directly at your teeth.
