Claims22
A method of affecting one or more microorganisms in an oral cavity, comprising:
- introducing a composition into the oral cavity, wherein said composition comprises a reactive species generating agent;
- and
- directing an output from a light emitting element at a portion of the soft tissue of the oral cavity for a period of time sufficient to generate one or more reactive species from said reactive species generating agent.
A method of reducing oral malodor comprising contacting a surface of a tongue with a device comprising one or more protrusions and a light-emitting element.
A method of reducing oral malodor comprising:
- depositing an effective amount of a composition onto a tongue, wherein said composition comprises a reactive species generating agent;
