Your gentle jaw devices may be cleaned with water and a brush. Do not use toothpaste. If small white spots appear on the device, this means you are not cleaning it well enough after each use. You can purchase denture cleanser tablets to remove these white spots, which are due to the tartar that can also build up on your teeth. Drop one tablet into very warm water (not hot), enough to cover the gentle jaw. Place the gentle jaw into the effervescing solution, which will change color as it cleans. After five minutes or more, remove the gentle jaw, and brush and rinse the device thoroughly. Do not place the gentle jaw in a dishwasher.
