New safety information on multiple-use dental dispensers released

The U.S. Food and Drug Administration recently released new safety information about multiple-use dental dispensers.

The new information, released in July, includes a definition of multiple-use dental dispensers, information on the importance of infection control and a series of do’s and don’ts.

According to the FDA, “Multiple-use dental dispensers, also called dental ‘syringes’ are devices used to deliver various dental products including impression materials, adhesives, dental composites, and endodontic (root canal) materials to a treatment site in the mouth. Multiple-use dental dispensers do not include disposable syringes or dental needles (hypodermic syringes) for injection of anesthetics.”

The FDA warns that contamination or infection control issues arise for suture patients when the body or housing of multiple-use dental dispensers “comes in contact with a previous patient’s cheek or lips, or when the dispenser is handled by a dental practitioner whose gloves have become contaminated with previous patient’s blood or saliva.”

Below is a list of do’s and don’ts from the FDA’s website.


  • Apply disposable barrier sleeves/wraps over multiple-use dental dispensers before use with each patient.
  • Use new, uncontaminated gloves when handling multiple-use dental dispensers.
  • Avoid contact of the reusable parts (e.g., the body of the multiple-use dental dispenser) with the patient’s mouth.

Do not:

  • Reuse the multiple-use dental dispenser if it becomes contaminated.
  • Reprocess a contaminated multiple-use dental dispenser by using chemical wipes or disinfectants.
  • Immerse multiple-use dental dispensers in a high level chemical disinfectant. This may damage the dispenser and the material contained in the device.
  • Sterilize multiple-use dental dispensers. This may damage the material contained in the device.
