GC Tooth Mousse is a topical, water-based, sugar-free cream. The milk protein is produced from casein. Those who are allergic to milk protein should not use it. Usage: A pea-sized amount of GC Tooth Mousse is applied to the tooth surface as a soft tissue with the help of fingertips. GC Tooth Mousse is absorbed by the teeth within two minutes. The mouth should never be rinsed or washed. You should not eat or drink anything for 30 minutes. It is especially recommended to apply before going to bed at night. If you are in the process of orthodontic treatment, apply Tooth Mousse around wires and brackets. Frequency of use should be consulted with a physician. There is no need to wash - it will be beneficial to keep it on the tooth surface as much as possible.
