How Water Flossers Work

First, water flossers use a targeted stream of water to clean between teeth:

They blast away plaque and food particles from between teeth and along the gumline.
The water penetrates periodontal pockets up to 6mm deep, making them ideal for people with gum disease or deep pockets.
They’re easy to use, requiring no fine motor skills, making them perfect for people with limited dexterity.
They’re gentle on sensitive gums, reducing irritation and bleeding.

How Interdental Brushes Work

Furthermore, interdental brushes are small, cone-shaped brushes that fit between teeth:

They physically scrub away plaque and food particles from between teeth, making them more effective at removing stubborn buildup.
They come in different sizes to fit different gap sizes, making them ideal for people with narrow or wide gaps.
They’re portable and affordable, requiring no electricity or water to use.
They’re better at cleaning around braces, implants, and other dental appliances.
