The Interdental brush, has the following characteristics:
Interdental brushes comes with a plastic cap. The cap can be used to protect the brush (if carried in your pocket or bag) and also to extend the handle. There is no cap with the grey brush (1.3 mm) as the bristles are too long.
Choose a brush size that will fit your interdental spaces. Very often you must have more than one size. If you are not sure, let your dentist or dental hygienist choose the right size(s) for you.
Don’t use toothpaste with the brush unless advised to do so by a dental professional. Too much toothpaste makes filament less effective. Use the interdental brush once a day. Change brush when it is getting worn
Effective cleaning with your interdental brush:
Use the correct size with the filaments filling the interdental space - never force into a space. Undue force and continuous bending may lead to fracture of the wire and cause injury.
