Water Flosser First, Then Brush (or Vice Versa) - The Order Doesn't Matter
The sequence of water flossing versus traditional flossing doesn't impact clinical outcomes - what matters is that you use interdental cleaning consistently as an adjunct to brushing. The provided evidence focuses on infection control in dental settings and comparative effectiveness of interdental aids, but contains no guidelines or research addressing the specific order of use.
What the Evidence Actually Shows
Water Flosser vs Traditional Floss Effectiveness
The research demonstrates that water flossers are equally effective or superior to traditional dental floss for plaque removal and gingival health:
- Water flossers show 29% greater overall plaque removal compared to string floss after single use 1
- For bleeding reduction around dental implants, 81.8% of sites improved with water flossers versus only 33.3% with traditional floss at 30 days 2
- Both methods achieve substantial plaque reduction (87-89%) with no significant difference in some studies 3
- Water flossers are 3.13 times more effective for reducing bleeding on probing when added to manual brushing 4
Clinical Recommendations
Use whichever interdental cleaning method you'll actually perform consistently - compliance matters more than the specific device:
Water flossers are particularly advantageous for:
Traditional floss remains effective when used properly, though water flossers access areas that may be physically inaccessible to string floss 5
The Missing Evidence
None of the provided guidelines [@1-6@] or research studies [@7-13@] address the sequence of interdental cleaning relative to brushing. The dental infection control guidelines focus on waterline maintenance and sterilization protocols in clinical settings - not home oral hygiene sequencing.
Practical Approach
Perform interdental cleaning (either method) at least once daily, ideally before bedtime, in conjunction with twice-daily brushing. The specific order is less important than:
- Thoroughness - ensure you clean all interdental spaces
- Consistency - daily use is essential
- Proper technique - follow manufacturer instructions for water flossers or proper flossing technique for string floss
Common Pitfalls to Avoid
- Don't skip interdental cleaning because you're unsure of the "correct" order
- Cost is the primary barrier to water flosser use (58% of dental professionals cite this) 7, but effectiveness justifies the investment for many patients
- Only 28.9% of dental professionals report adequate training on oral irrigators 7 - seek proper instruction if using a water flosser
The bottom line: Choose the interdental cleaning method you'll use consistently, and don't worry about the sequence relative to brushing.
