Frequently asked questions
How do I read the reference?
1st digit = quadrant, 2nd = tooth position, 3rd = size. ST-5K-211 is therefore tooth 21 (upper left central incisor), size 211.

Never more than 30 days. If it stays for a few days, its gingival edge must be no deeper than 1 mm inside the sulcus.
