DENT. Plaque Tester Cotton Swab Type Individually Wrapped Quantity: 20 swabs *We can also accommodate 1 sheet (10 swabs) for 580 yen. You can take the cotton swab soaked in the staining solution out of the aluminum pack and use it immediately. After use, returning it to the pack prevents the dye from sticking to your fingers or clothes. How to Use 1. Take the cotton swab soaked in the staining solution out of the aluminum pack and apply it to the surface of your teeth (especially the border with the gingival margin, interdental areas, lingual side, and occlusal surfaces). 2. Rinse your mouth lightly with a small amount of water. 3. The areas stained red-purple are plaque. Make sure to check those areas carefully. 4. Place the bristles of your toothbrush on the red-purple stained areas, brush carefully, and remove the plaque. How to Take Out 1. The cotton swab soaked with the staining solution is inside the aluminum pack on the side with the cotton ball illustration. 2. Twist the stick side to open it, and pull out the stick side of the pack. 3. Hold the stick part with your fingers and gently pull out the pack on the opposite side (cotton ball part). *Be careful not to touch the cotton ball part with your hands or clothes.
