Methods and systems for temporarily coating intra-oral devices (e.g., orthodontic brackets (104) and/or wires (106)) so as to reduce discomfort to soft tissues within a patient's mouth. One embodiment of such a system includes at least one orthodontic bracket (104) or orthodontic arch wire (106) and a two-part polymerizable temporary coating composition (102) for use in coating selected surfaces of the brackets (104) and/or wires (106). One silicone polymerizable two- part composition (104) includes a vinyl siloxane component, a cross-linking component, and a catalyst activator initially divided between the two parts so that at least one of the components is kept separate from at least one other component (i.e., all three components are not initially commingled). Upon mixing of the first and second parts, the composition begins to polymerize.
