A composition having a pH ranging from 6.0 to 8.0 comprising:

eugenol,
at least one crosslinked polymer of acrylic acid or other gelling agent, and
at least one polysorbate in an amount of 25-50 wt % of the total weight of the composition;
wherein said composition contains an amount of eugenol sufficient to reduce the Vickers hardness of a cured or hardened orthodontic bonding adhesive cement or resin to a value of 70 or less after contact for at least 10 mins and/or is sufficient to reduce debonding force needed to remove a metal bracket from an enamel surface of a tooth compared to debonding force needed to remove a metal bracket not contacted with the composition.
