10. Troubleshooting & FAQ
- Q: Do I need to brush my teeth to use the water flosser?
- A: The water flosser is a complementary tool to your toothbrush. While a toothbrush cleans the surface of your teeth, the water flosser effectively cleans hidden areas like the gingiva, pits, and cavities, enhancing overall oral hygiene.
- Q: Will my gums bleed when using the water flosser for the first time?
- A: If your gums are inflamed, they might bleed during initial use. This usually improves significantly after about a week of consistent use. Persistent use can effectively improve gum health.
- Q: Can I add other liquids to the tank?
- A: Ordinary mouthwash can be added to the water tank. It is recommended to use a 1:1 ratio with water. Always rinse the water tank with clean water after using any additives.
- Q: Can a water flosser remove tartar?
- A: Consistent use of the water flosser can deeply clean the mouth, reduce plaque, and prevent the formation of dental calculus. However, it cannot directly flush out existing dental tartar.
- Q: How long can it be used with a full water tank?
- A: The 330ML water tank provides approximately two minutes of continuous use.
- Q: What is the jet pulsation frequency?
- A: The device operates with a jet pulsation frequency of 1600 to 1999 impulses per minute.
- Q: Is the water jet constant or pulsating?
- A: The water jet principle is pulsating, which is effective for cleaning.

11. User Tips
- For optimal comfort and to prevent gum irritation, especially if you are new to water flossing, always begin with the "Soft" mode.
- If you have sensitive gums, the "Soft" mode is specifically designed to provide a gentle yet effective cleaning experience.
- When using mouthwash, remember to dilute it with water in a 1:1 ratio. This helps prevent potential damage to the device and ensures a balanced cleaning solution. Always rinse the water tank with clean water immediately after using mouthwash.
- Take advantage of the "DIY" mode to personalize your flossing experience. You can adjust the water pressure between 20-140 PSI to find the perfect intensity for your needs.
