Urgo Canker Sores Filmogel of Urgo indicated for the treatment of canker sores and small oral wounds. It is a liquid appendix that once applied, forms a thin, flexible and resistant protective film even while it comes, for a quick treatment of canker sores. Provides quick and prolonged pain relief. The protective film protects the injury from external aggressions (food, drinks, dental prostheses) and favors the healing of canker sores. It is recommended to apply the product on the injury with the help of the spatula-applicator so that it completely covers the entire area to be treated. (Pre-remove excess product by resting the spatula on the edge of the bottle). Let dry for 10 seconds, keeping the mouth open until the formation of a visible film appears. If the injury is not well covered, repeat the operation. Apply urgo canker sores as often as necessary. Up to 4 times a day, preferably before eating, until healing is complete (3 to 5 days). As long as the film is visible, there is no need to re-apply. Disinfection of the spatula is guaranteed thanks to the composition of the product. Therefore, it is not necessary to clean the spatula after each application. Keep the container tightly closed after each application.
