Flossing is a burden to many and an exciting activity to none (unless, perhaps you’re a dentist). Still, experts consider it a crucial part of one’s oral hygiene since doing it daily helps to prevent gum disease, cavities and bad breath.

What To Consider In A Water Flosser
While your flossing preferences will vary according to your specific oral care needs and budget, there are certain characteristics to pay attention to when making your pick. Here’s what to look for in the device.
Reservoir Capacity
The reservoir is a key component of the water flosser, since it correlates to how long each session is; you can fill it with either water or mouthwash. On cordless models, water flows directly into the nozzle attachment, whereas countertop units funnel water through a tube connected to the nozzle.
A larger tank leads to more flossing time, but it will definitely require a bulkier design. Consider whether you plan to travel with your water flosser or keep it stationed at home. “If you’re not going to be doing much traveling, having a A larger reservoir is more convenient,” says Fung.
Ease Of Use
Most experts agreed that all water flossers are uniformly easy to use. With the push of a button or flick of a dial, most take about 60 to 90 seconds to clean the entire mouth. They require little maintenance other than replenishing the reservoir with water.
Intensity
According to San Antonio-based founder of Ingram Hills Dental Dr. Michele Bishop, water flossers can range from 10-160 PSI, with a range of settings that users can adjust based on their comfort level. “On average, 60-75 PSI is most effective for removing plaque in between teeth, if it’s being used with the proper technique,” she says.
While 100-160 PSI is the strongest setting, Bishop cautions against confusing force and high pressure with technique. “It’s important to know how to use the water flosser to the best of its ability: angling the tip to ensure it’s getting in between the teeth is key to its effectiveness,” she says. In a dentist office, the average PSI is 60; however, Dr. Bishop adds these are often used in concert with ultrasonic tips and micropowders to remove stains.
Finally, it’s important to note that the intensity varies greatly between cordless and countertop units. The best and highest levels will be with the plug-in units. “The portable models will have a lower intensity, but work great for those with braces in between meals,” says Fung.
Usage
Before you go tossing the dental floss, experts agreed that water flossing is a great addition to your oral care regimen, but it’s not a perfect replacement for the string version paired with brushing. “Water flossing is not as effective as regular flossing, so ideally you would use it after using traditional floss,” says Huang. For an even deeper clean, Lieb recommends using GUM soft picks to go between the teeth. This action will remove any lingering plaque buildup.
Accessories
Water flosser accessories can add even more customization to the teeth cleaning experience. While not absolutely essential, Fung suggests using models that have “separate tips for orthodontics, general use and dental appliance cleaning.” For portable versions, most come with a convenient traveling case and global voltage capabilities.
