Indications for Use

OpalDam™ and OpalDam™ Green

OpalDam and OpalDam Green resin barriers 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 color of OpalDam Green resin barrier shows its location on the gingiva and teeth for more effective coverage.

Protects Soft Tissues

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

Seal Matrices into Place


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

Technical Details

Easy to Place

OpalDam and OpalDam Green resin barriers 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 resin barriers 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 resin barriers 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 resin barriers are extremely versatile and can be used:

  • 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
