GUM Proxabrush Go-Betweens (Wide) Review: The Easiest Way to Clean Where Your Toothbrush Can’t

If you’re brushing twice a day but still dealing with plaque buildup, gum sensitivity, or that annoying “something stuck between my teeth” feeling, you’re not alone. Traditional brushing only cleans about 60% of tooth surfaces. The rest? That’s where plaque loves to hide—and where flossing is supposed to help.

But let’s be honest: flossing isn’t everyone’s favorite habit. It can be awkward, time-consuming, and frustrating—especially if you have braces, implants, bridges, or wider gaps between teeth.

That’s exactly where GUM Proxabrush Go-Betweens (Wide) come in. These soft-bristled interdental brushes are designed as an easy, effective alternative to floss, helping you clean deep between teeth with minimal effort. In this in-depth review, we’ll break down what makes them special, who they’re best for, and whether they’re worth adding to your daily oral care routine.

What Are GUM Proxabrush Go-Betweens?

GUM Proxabrush Go-Betweens are reusable interdental brushes designed to clean between teeth where a standard toothbrush can’t reach. The Wide (3614RQ) version is the largest size in the Proxabrush line, specifically made for people with larger interdental spaces, dental work, or orthodontic appliances.

Instead of sliding string floss between teeth, you gently guide a small brush through the space, sweeping away plaque and food particles. Think of it as a tiny bottle brush for your teeth—but much softer and dentist-approved.

At a price point of $4.48 for a 10-count pack, these brushes are an affordable upgrade to your oral hygiene routine.

Why Between-Teeth Cleaning Matters More Than You Think

Before diving into features, it’s important to understand why products like Proxabrush matter.

Research consistently shows a strong link between oral health and overall health. Poor gum health has been associated with conditions such as heart disease, diabetes complications, and inflammation throughout the body. Plaque buildup between teeth is one of the main contributors to gum disease—and brushing alone simply isn’t enough.

The challenge?

• Tight schedules

• Difficulty using floss

• Braces or dental appliances

• Reduced dexterity

GUM designed Proxabrush Go-Betweens to remove these barriers and make daily interdental cleaning fast, simple, and effective.

Key Features and Benefits (In-Depth Analysis)

1. Deep Cleaning with Soft, Triangular Bristles

The standout feature of GUM Proxabrush Go-Betweens is their soft, triangular bristle design. According to the brand, this shape delivers up to 25% more effective plaque removal compared to standard round-bristle interdental brushes.

Why it matters:
The triangular shape allows the bristles to adapt to the natural contours of teeth and gums, cleaning more surface area without aggressive pressure. This makes them gentle enough for daily use while still being highly effective.

Real-world benefit:
Cleaner interdental spaces, healthier gums, and noticeably fresher breath—often within days of consistent use.

2. Wide Size for Larger Interdental Spaces

The Wide (3614RQ) version is specifically designed for people who have:

• Naturally wider gaps between teeth

• Gum recession

• Braces or orthodontic hardware

• Bridges, crowns, or implants

GUM also offers Ultra Tight, Tight, and Moderate sizes, but this wide version is ideal when standard floss feels too thin or ineffective.

Why it matters:
Using the wrong size interdental brush can either be ineffective (too small) or uncomfortable (too large). The Wide Proxabrush fills the space properly, allowing for thorough plaque removal without forcing or scraping.

3. Compact, Reusable, and Travel-Friendly Design

Each Proxabrush Go-Between comes with:

• A protective travel cap

• Hygienically treated bristles

• Up to 10 days of reuse per brush

They’re small enough to fit into:

• Purses

• Pockets

• Travel kits

• Desk drawers

Why it matters:
Consistency is key in oral hygiene. A tool that’s easy to carry and quick to use dramatically increases the chances you’ll actually use it every day—whether you’re at home, at work, or on the road.

4. Safe and Effective for Braces & Dental Appliances

This is where GUM Proxabrush truly shines.

Each brush features a nylon-coated wire, which allows it to clean around:

• Braces

• Bridges

• Implants

• Crowns

• Orthodontic fixtures

without scratching metal surfaces or causing galvanic shock (an unpleasant sensation caused by metal contact in the mouth).

Why it matters:
Flossing around braces and implants can be frustrating and time-consuming. Proxabrush Go-Betweens slide easily into hard-to-reach areas, making them one of the best interdental cleaners for orthodontic patients.

5. Ergonomic, Non-Slip Handle with Bendable Neck

The rubberized, non-slip handle offers excellent grip, even when wet. The bendable neck allows you to angle the brush for better access to back teeth.

Why it matters:
If you struggle with dexterity or simply hate awkward hand positions while flossing, this design makes interdental cleaning significantly easier and more comfortable.

How to Use GUM Proxabrush Go-Betweens Effectively

Using these brushes is simple:

1. Choose the correct size (Wide, in this case).

2. Gently insert the brush between teeth—never force it.

3. Move it back and forth a few times to remove plaque and debris.

4. Rinse after use and recap for storage.

Use once daily, ideally after brushing, for best results.
