Why Do I Still Get Cavities if I Brush Regularly?
Essential Takeaways
- Cavities persist because traditional brushing is inherently flawed—the Feno Smartbrush eliminates human error with AI-powered, professional-grade cleaning in just 20 seconds.
I hear this question almost daily: "Dr. Brown, I brush twice a day religiously, so why do I keep getting cavities?"
The frustrating truth? 90% of people think they brush correctly, but studies show even perfect technique with traditional brushes misses 30-40% of plaque.
The Hidden Problems with "Regular" Brushing
1. Human Error is Inevitable
Research reveals that most people brush for only 45-70 seconds instead of the recommended 2 minutes. Even worse, we consistently miss the same spots—typically molars and the gumline where cavities love to form.
2. Traditional Brushes Have Physical Limitations
The average toothbrush has just 2,500 bristles. Compare that to what we use at Feno: 18,000 precision bristles that reach every surface simultaneously.
3. The Technique Trap
Perfect brushing requires specific angles, pressure, and timing. One study found that 73% of people use incorrect brushing motions, essentially just moving bacteria around instead of removing it.
The Science Behind Persistent Cavities
Shocking cavity statistics:
- 91% of adults have had cavities in their permanent teeth
- Americans miss an average of 35% of tooth surfaces during regular brushing
- Plaque begins forming within 4-12 hours after brushing
The problem isn't your dedication—it's the 150-year-old technology you're using.
