Gum proxabrush
A proxabrush is an interdental brush with a handle that cleans plaque from spaces around teeth, bridges, braces, and other dental work.
The short answer
A proxabrush is an interdental brush with a handle that cleans plaque from spaces around teeth, bridges, braces, and other dental work. The bristles should touch the sides of the teeth and pass through the space without being forced.
How is a proxabrush shaped to clean tight spaces?
The brush has a small cylindrical or tapered tuft supported by a wire or flexible core. It cleans where a regular toothbrush cannot reach, including under bridge connectors and around orthodontic brackets, while the handle helps people with limited finger control.
How can you use a proxabrush without injury?
Choose a size that enters the space with gentle resistance, insert it at the gumline, and move it back and forth without twisting the wire. Rinse the brush during use, let it dry, and replace it when the bristles bend or the core becomes rough.
When should a proxabrush problem be checked?
Ask for an assessment if the brush cannot enter, causes repeated bleeding, catches on a filling, or leaves a sore area. A dentist or hygienist can measure the spaces and show whether a brush, floss threader, water flosser, or another tool fits better.
Which proxabrush size is right for each space?
Ask which diameter suits each gap, whether the wire could damage a restoration, and how to clean beneath a bridge or around braces. Ask for a hands-on demonstration because one size may not fit every space.
Frequently asked questions
Is a proxabrush the same as floss?
No. A proxabrush cleans an open space with bristles, while floss slides through tighter contacts and under some gum margins.
Can I use one brush for every gap?
Often no, because the spaces between teeth can have different widths and appliance designs.
