Most people know they should clean between their teeth, but traditional flossing has a surprisingly high dropout rate. European dental professionals have embraced interdental brushes as the primary recommendation for between-teeth cleaning — and the evidence supports this shift.
The Problem with Floss
While flossing is better than nothing, it has limitations. The technique is difficult to master, most people don't use the correct C-shape motion, it can't clean concave root surfaces effectively, and compliance rates are notoriously low because many people find it awkward and time-consuming.
Interdental Brushes: The European Standard
European dental associations increasingly recommend interdental brushes as the first choice for between-teeth cleaning. Products like GUM Soft-Picks offer rubber interdental brushes that are gentle on gums while effectively removing plaque.
Research shows interdental brushes remove more plaque between teeth than floss, are easier to use correctly, are more effective at reducing gingivitis, have higher patient compliance rates, and can reach areas floss can't access.
Choosing the Right Size
Interdental spaces vary throughout your mouth, so you may need multiple sizes. The brush should fit snugly but not force its way through:
- Very narrow spaces (front teeth): Extra fine or ultra fine brushes
- Moderate spaces: Fine to medium brushes
- Wider spaces (back teeth): Medium to large brushes
Your dental hygienist can help you determine the right sizes for your mouth. A brush that's too small won't clean effectively, while one that's too large can damage the gum tissue between teeth.
Proper Technique
- Insert the brush gently between teeth at gum level
- Move the brush back and forth 2-3 times
- Don't force it — if it doesn't fit, try a smaller size
- Clean all interdental spaces once daily
- Replace the brush when bristles become worn (typically after 1-2 weeks)
Water Flossers
Water flossers (oral irrigators) use a pressurized stream of water to clean between teeth and along the gumline. They're particularly useful for people with braces, bridges, implants, or limited manual dexterity. While they don't replace mechanical cleaning entirely, they're excellent for flushing debris and bacteria from hard-to-reach areas.
Building the Complete Oral Hygiene Routine
European dental professionals recommend: brush twice daily with fluoride toothpaste, clean between teeth once daily with interdental brushes, use a fluoride mouthwash at a different time from brushing, and see your dentist and hygienist regularly. Adding a weekly fluoride gel treatment can provide extra cavity protection for those at higher risk.
