An oral treatment composition that includes a carrier, an active agent and a silicon dioxide compound. The active agent can be a variety of compositions, such as dental whitening or bleaching agents, desensitizing agents, antimicrobials, anti-plaque agents, remineralizing agents, anti-tartar agents, mouth fresheners, and anesthetics. Optionally, a processing aid can be added to the composition to streamline manufacture of the gel. The composition can be formed as a bead in a dental tray so that when a user applies the dental tray to their dental arch, the bead readily spreads over the surfaces of the teeth without the user having to supply significant force to achieve such spreading.
