Frequently Asked Questions

What’s the science behind flossing?

While there is a surprising deficit of peer-reviewed studies concerning flossing, this cleaning method has been recommended by dentists for decades. The biggest reason behind flossing skepticism is the frequency with which people floss incorrectly. Flossing is supposed to scrape the edges of teeth lightly to dislodge food particles; however, many individuals who floss use it in an ineffective, horizontal sawing motion. Regardless, flossing correctly will do little good without proper brushing. Water flossers are a perfect supplement to brushing because they effectively dislodge food without causing undue stress on the gums. This cuts down on inflammation and the spread of bacteria.   

How often should I use my cordless water flosser?

Flossing should be done after any meal where food has become stuck in between your teeth to the point of discomfort. If not properly cleaned, this can develop into interproximal dental plaque, which is a challenging form of build-up to fix. However, as far as specific recommendations go, the American Dental Association states that you should floss once a day and brush twice a day for no less than two minutes each brush. While proper flossing can lead to stronger gums, you should take caution while flossing. Incorrect use can lead to extra bleeding or inflammation, results that can attract bacteria by themselves. It’s always preferable to floss before brushing and mouthwash because this ensures any sensitive areas are thoroughly sanitized once you’re done.
