Opalescence™ Endo is a fast and easy internal bleaching treatment designed specifically to whiten non-vital, endodontically treated, discoloured teeth.

Designed for the “walking-bleach” technique, Opalescence Endo from Ultradent™, comes in a conveniently pre-filled syringe, requiring very little preparation or chair-time. The special, 35% hydrogen peroxide whitening gel is sealed in the coronal portion of the pulp chamber to whiten the tooth from the inside out. Opalescence Endo is activated by body temperature and is left in the tooth for 1-5 days. Other features and benefits include:

  • 35% hydrogen peroxide
  • Activated by intra-oral temperature
  • High viscosity formula, allows for easy placement
  • 1-5 day treatment

Indications for Use

IMPORTANT: Prior to placing Opalescence Endo, a glass ionomer must be placed to the level of the CEJ to prevent peroxide from entering the pulp canals.

Opalescence Endo Non-Vital Whitening Gel Step by Step

See Instructions for Use for complete instructions, warnings, and precautions.

  1. Before starting the Opalescence Endo procedure, a glass ionomer should be placed on the floor of the pulp chamber to seal the obturation from penetration of the hydrogen peroxide. Place Opalescence Endo into the canal, stopping 2mm from the access opening.

Minimally Invasive

A dark tooth—especially in the anterior region—can be embarrassing for anyone. In the past, the only options to correct such an issue involved invasive procedures like placement of crowns and veneers. But with Opalescence Endo whitening gel, you can effectively whiten a dark, non-vital tooth while keeping natural tooth structure intact.


Self-mixed pastes are of a relatively soft consistency, which makes it difficult to hermetically seal the cavity after placement. By contrast, Opalescence Endo whitening gel is considerably more viscous, easy to place, and can be safely covered with temporary material.

Easy to Apply

Self-mixed pastes need to be “spooned” with a spatula from a dappen dish into the cavity. Opalescence Endo whitening gel is syringe delivered for easy, clean, and fast delivery.


Self-mixed pastes do not always contain the same standardized quantity of active ingredient, and thus there may be fluctuations in their efficacy. In many cases, the material needs to be replaced several times. Opalescence Endo whitening gel always has the same concentration of active ingredient, and whitening results are achieved after just one to five days. Opalescence Endo gel is ready to use, economical, and has a long shelf life.

Opalescence Endo Walking Bleach Mini Kit (Item Number: 701270) includes:

Q: What is the active ingredient in Opalescence Endo whitening gel?

A: 35% hydrogen peroxide.

Q: How long do I leave Opalescence Endo whitening gel in the pulp chamber?

A: We recommend you have the patient come back after 1 to 5 days to have the whitening gel removed and the restoration completed.

Q: Can I place Opalescence Endo whitening gel below the alveolar crestal bone?

A: No. Opalescence Endo whitening gel should always be placed above the alveolar crestal bone.

Q: What if the non-vital tooth has restorative material in it from previous restorations?

A: All previous restorative materials need to be removed before placing the bleach in the tooth. This will allow the bleaching agent to come in contact the maximum amount of tooth structure for optimal results.

Q: Should I err on the side of overbleaching or underbleaching?

A: Err on the side of overbleaching, as some regression of the whitening will occur.

Q: How should I store Opalescence Endo whitening syringes?

A: Opalescence Endo whitening gel should be stored in a refrigerator.

Q: Will teeth whitening affect bond strength?

A: Even though whitening agents release a great amount of oxygen into the tooth, existing bonds are not weakened. If whitening before bonding, allow a period of 7–10 days after whitening. The high concentration of oxygen in the tooth could significantly and adversely affect polymerization of the resins.
