Safe Effective ? ? ? ? How to prevent water from splashing everywhere? Put the water flosser in your mouth before you switch it on and partially close lips enough to prevent splashing, let water flow into sink. Keep unit upright for continuous water flow. Switch it off before pulling it out of the mouth when finished. Can a water flosser be too strong? If your gums bleed while using, it could indicate gum disease or inflammation, not necessarily the pressure of the water flosser. However, always start with the soft setting and consult a dentist if bleeding persists for over two weeks. Do you need to add water many times during use? No, this water tank has a upgrade super larger capacity of 300ml, it is enough for a single cleaning,very convenient. And the large opening is more user-firendly to clean and refill. How do I change flosser tips? Every water flosser has a button on the machine, which allows you to remove the tip. Please make sure to press the button on the machine before inserting or taking out the tip, otherwise, it will be easily stuck into the machine. What should I do if my water flosser doesn?t work properly after priming? Check for blockages, ensure the reservoir is properly seated.
