Gum wide proxabrush
A wide interdental brush can clean a larger gap when its bristles fill the space gently without forcing the wire against gum tissue.
The short answer
A wide interdental brush is designed for an open space between teeth, around bridges, or beside implants; the correct size fills the gap without bending or forcing.

What is the direct answer?
What does this question mean?
It uses a coated wire core with angled bristles to disrupt plaque on tooth surfaces that a toothbrush cannot reach. An oversized brush can traumatize papillae, while an undersized one may leave deposits.
What can you do next?
Measure the space with a dental professional, insert the brush horizontally or at the angle shown, and make a few gentle passes. Rinse the brush and replace it when bristles wear.
When should you seek dental care?
Seek care if cleaning causes persistent bleeding, pain, pus, or a sore that does not settle. A dentist can check for calculus, periodontal pockets, decay, or an ill-fitting restoration.
What should you ask the dentist?
Ask which brush diameter fits each gap, whether a wire-free brush is needed, and how to clean around crowns, bridges, braces, or implants.
Frequently asked questions
Can this have more than one cause?
Yes. The examination distinguishes local irritation, inflammation, tooth disease, and structural factors.
What happens at the appointment?
The dentist reviews symptoms, examines the area, and explains findings and treatment choices.
