Gum go betweens proxabrush cleaners
Interdental brushes clean between teeth when the brush fits snugly without force; the correct size depends on each space.
The short answer
Interdental brushes clean between teeth when the brush fits snugly without force; the correct size depends on each space. A brush that bends or needs pressure is too large or has the wrong shape.

What is the direct answer?
What does this question mean?
Go-Betweens and Proxabrush are names used for small interdental cleaning brushes. Their wire or flexible core carries bristles into the space between teeth, around bridges, or beneath orthodontic wires.
What can you do next?
Start with the smallest brush that cleans the space and insert it horizontally where possible, using a gentle in-and-out motion. Rinse the brush between spaces and use a new one when the bristles wear or the wire distorts.
When should you seek dental care?
Ask for instruction if every brush feels loose, catches, or causes repeated bleeding after regular cleaning. Dental care is needed for gum recession, loose teeth, persistent swelling, or food trapping caused by decay or a broken filling.
What should you ask the dentist?
Ask which brush size fits each space and whether floss, a water flosser, or a specialised brush is better around your restorations. Ask how to clean beneath bridges, implants, or braces without damaging the tissues.
Frequently asked questions
Should an interdental brush bleed?
Initial bleeding can occur with inflamed gums, but regular bleeding warrants technique and gum assessment.
Can I use one size everywhere?
Usually not, because tooth spaces vary in width and shape.
