NeoDrys® Flex: NeoDrys® Flex is a sublingual absorbent that absorbs moisture for up to 15 minutes. It is designed to contour the lingual side of the lower arch to control moisture from the sublingual and mandibular glands. The super absorbent polymer traps moisture as a gel when in contact with saliva. NeoDrys® Flex may be used by itself or along with NeoDrys® to protect procedures requiring a dry field. The absorbent removes easily with gentle water spray.
