We're disappointed to hear you had that sensation, and we're happy to help you. Safety is our top priority, and our mouthwashes are thoroughly evaluated to be safe when used as directed. Flavor oils, surfactants/foaming agents, tartar control agents, and abrasives all have some potential to cause irritation. While all of our products are safe and effective, you may not be able to tolerate a particular formulation. If irritation persists or becomes uncomfortable discontinue use and consult with your dentist. Your dentist may recommend an alternate version such as a sensitivity product. Please give us a call and we're happy to make a recommendation and answer any questions you may have.
