Proxabrush 618
A Proxabrush is an interdental brush, and the correct size is the one that cleans the space without forcing the wire or scrubbing the gum.
The short answer
A Proxabrush is a small interdental brush with bristles around a wire or flexible core, used to clean spaces a toothbrush cannot reach.
What is the direct answer?
What does this question mean?
The brush removes plaque from the sides of teeth, under fixed bridges, around braces, and near some implants. A model number identifies a product variant, but it does not by itself determine the correct size for every mouth.
What can you do next?
Select a brush that passes through the space with gentle resistance, insert it along the natural gap, and move it in and out without twisting or forcing it. Ask for sizing help when spaces differ, and replace a bent or worn brush.
When should you seek dental care?
Seek dental advice if use causes repeated bleeding, pain, recession, or wire damage, or if a brush cannot pass through a space that traps food. Persistent bleeding may reflect gum inflammation rather than poor technique alone.
What should you ask the dentist?
Ask which diameter fits each gap, whether to use floss under a bridge, how to clean around braces or implants, and when a bleeding site needs periodontal assessment.
Frequently asked questions
Is a Proxabrush better than floss?
It depends on the space and anatomy: a brush often suits open spaces, while floss can clean tight contacts that a brush cannot enter.
Why does my interdental brush bend?
The brush may be too large, inserted at the wrong angle, or meeting a tight contact; do not force it, and ask for a smaller size or another method.
