Dear Kosher Spirit,
Does denture adhesive require a hechsher for year round use? Are there any special issues for Pesach?

Rabbi Chanowitz responds:

Unflavored denture adhesive does not require any kosher supervision for year round use. In addition, it does not contain any ingredients that are sensitive for Passover. For instructions on how to properly clean your dentures before Pesach, please consult your local Orthodox rabbi.

Did you know that the rubber bands used for braces can be coated with starch, so they should be rinsed well before use during Pesach.
