Proxabrush
A Proxabrush is an interdental brush that cleans plaque from spaces a toothbrush cannot reach, using a small bristled wire or coated core sized to the gap.
The short answer
A Proxabrush is a brand-style name commonly used for an interdental brush. Its filaments clean the sides of adjacent teeth and around bridges, braces, implants, and other areas where a toothbrush cannot contact the surface.
What is the direct answer?
What does this question mean?
The brush should pass through the space with light resistance while the filaments touch both tooth surfaces. A brush that bends sharply or needs force is too large; a brush that passes without contact may be too small.
What can you do next?
Choose the smallest size that fills the space, insert it gently without twisting force, move it in and out, and rinse it after use. Use floss where the contact is too tight for a brush and follow orthodontic or implant instructions around appliances.
When should you seek dental care?
Ask a dentist or hygienist to size the brush at several sites because spaces can differ around the mouth. Seek care for persistent bleeding, swelling, pain, or a brush that catches on a rough filling.
What should you ask the dentist?
Ask which diameter fits each space, whether a floss threader is needed at tight contacts, and how to clean around bridges, braces, or implants. Ask when a worn wire or splayed brush should be replaced.
Frequently asked questions
Can an interdental brush replace floss?
It can clean many open spaces effectively, but tight contacts may still require floss or another thin interdental aid.
Why does the brush bleed?
Bleeding can reflect inflamed tissue or contact from excessive force; gentle daily use and an examination can clarify the cause.
