Indications for Use

OpalDam and OpalDam Green

​OpalDam and OpalDam Green are unique, light-reflective, passively adhesive (sealing) light-cured resins. Their methacrylate base is designed with adequate strength to maintain a barrier yet removes easily from embrasures and undercuts. The contrasting green colour of OpalDam Green shows its location on the gingiva and teeth for more effective coverage.


OpalDam® and OpalDam® Green

Protects Soft Tissues

​OpalDam and OpalDam Green can be used to protect the soft tissues any time a harsh chemical is used nearby.

OpalDam Green

Seal Matrices into Place

​When a matrix doesn’t fit well around a severely compromised tooth, use OpalDam or OpalDam Green to hold the matrix in place.

Technical Details

Easy to Place

​OpalDam and OpalDam Green are easily expressed directly where they’re needed in the mouth via the simple syringe-and-tip delivery.

Easy to Remove

​OpalDam and OpalDam Green remove easily from the mouth. Simply use an explorer or other instrument to cleanly break the cured resin from undercuts and discard.

Perfect for In-Office Whitening Procedures…

​When whitening agents with higher concentrations of hydrogen peroxide are used, they can irritate the gingiva. Expressing a ribbon of OpalDam or OpalDam Green along the gingival margin protects the soft tissues, keeping them comfortable during treatment.

...and So Much More!

In addition to the traditional use with whitening procedures, OpalDam and OpalDam Green are extremely versatile and can be used:

  • As a barrier for root canals
  • To prevent saliva leakage around the rubber dam clamp
  • To help hold a matrix in place around a severely compromised tooth
  • To protect the soft tissue from air abrasion
  • Any time you’re using a harsh chemical near the tissue


OpalDam and OpalDam Green Application

  1. 1

    ​Apply a barrier of OpalDam or OpalDam Green 4–6mm wide on the gingiva. Seal interproximal spaces. Overlap resin approximately 0.5mm onto dry enamel to seal. Extend resin one tooth beyond last tooth whitened. Light cure with a scanning motion for 20 seconds.

  2. 2

    Remove cured resin quickly and easily in one piece or a few large pieces. Check interproximally for retained resin. OpalDam and OpalDam Green are designed to easily remove from embrasures and undercuts.


  • What is the difference between OpalDam and OpalDam Green?

    ​Only the color. Many clinicians prefer to use OpalDam Green during an Opalescence Boost procedure because the green color contrasts so well with the color of the teeth, gingiva, and bleaching gel.

  • How long does OpalDam need to be cured before its polymerized?

    ​Light cure OpalDam and OpalDam Green for 20 seconds using a scanning motion. Always be sure to check the resin with an explorer to make sure it’s completely polymerized.

  • Are OpalDam and OpalDam Green gluten free?
