1. Make sure you have the proper aligner – the upper for your top teeth and the lower for your bottom teeth.
2. To help avoid confusion, each aligner is engraved with your unique case number, a “U” for upper and an “L” for lower, followed by the stage number.
3. You may insert either the upper or lower aligner first. When inserting each aligner, gently push the aligners over your front teeth. Then apply equal pressure, using your fingertips, to the tops of your left and right molars (back teeth) until the aligner snaps into place.
4. Do NOT bite your aligners into position. This may damage them.
