Understanding, Avoiding, and Correctly Treating Abfraction Lesions
Many people believe that thorough toothbrushing is automatically good for their teeth. However, the exact opposite can happen:
Incorrect brushing can permanently damage your teeth.
A commonly underestimated problem are so-called abfraction lesions – small but deep-seated damage to the tooth structure, often only noticed when pain occurs.

What are abfraction lesions?
Abfraction lesions are non-carious tooth structure losses that typically occur at the junction between the tooth crown and the neck of the tooth.
They look like small indentations or "notches" on the tooth – hence the name.
Typical locations:
- Incisors and canines
- Outer sides of molars
- Area near the gums
Precisely where many people press particularly hard when brushing.
The Main Cause: Incorrect Brushing Technique
The most common cause is surprisingly simple:
Horizontal "Scrubbing"
When you clean your teeth with sideways movements, the following happens:
- The bristles compress
- You concentrate pressure on the neck of the tooth
- The brush acts like a fine saw
Over time, the tooth structure is literally worn away
Further Risk Factors
In addition to technique, other factors play an important role:
1. Toothbrushes that are too hard
- Increase mechanical stress
- Promote gum recession
2. Excessive pressure
- Massively increases abrasion
3. Abrasive toothpastes (high RDA value)
- Act like sandpaper on tooth enamel
The combination of pressure + wrong technique + abrasive toothpaste is particularly dangerous
The RDA Value: An Underestimated Factor
The so-called RDA value (Relative Dentin Abrasion) indicates how much a toothpaste abrades the tooth surface.
- 🔴 Too high (>100) → harmful to tooth enamel
- 🟡 Too low (<40) → insufficient cleaning
- 🟢 Optimal: 60–90 → effective and gentle care
High-quality oral care products transparently state this value.
How can abfraction lesions be avoided?
The good news:
In most cases, these damages are completely avoidable
The correct brushing technique
- No horizontal movements
- Instead: gentle, vertical or circular movements
Minimal pressure
- The toothbrush should clean – not scrub
Use ultra-soft bristles
- Reduce mechanical stress
- Protect tooth necks and gums
Choose a gentle toothpaste
- Medium RDA value
- Remineralizing ingredients
What to do if defects are already present?
Once abfraction lesions have occurred, they cannot reverse on their own.
Treatment options:
- Composite fillings from the dentist
- Sealants
- Treatment of sensitivity
- Nevertheless:
Prevention is significantly easier – and ultimately the better solution
The Solution: Modern, Gentle Oral Care
This is precisely where Snow Pearl's philosophy comes in:
Maximum cleaning with minimal stress
Ultra Soft Toothbrushes with KONEX HD Technology
- Up to 8x thinner bristle tips than conventional brushes
- Extremely flexible yet stable
- Thoroughly clean uneven surfaces
- No "sawing effect" on the tooth neck
- No unnecessary pressure
- Optimal for sensitive teeth
Why this is crucial
Conventional toothbrushes:
- too hard
- too thick bristles
- too aggressive
Snow Pearl brushes:
- gentle on the gums
- gentle on tooth structure
- yet highly efficient
This combination is crucial for preventing abfraction lesions.
Practical Experience
In our dental practice in Zurich, we see the consequences of incorrect oral care daily.
Since we consistently use ultra-soft toothbrushes, we observe:
- less gum recession
- significantly fewer abfraction lesions
- more satisfied patients
The positive feedback confirms:
Gentle oral care is the key to long-term healthy teeth
Conclusion
Abfraction lesions don't happen overnight – but through daily habits.
The decisive factors are:
- correct technique
- correct toothbrush
- correct toothpaste
Those who make the right choices here can permanently protect their teeth.
Snow Pearl represents a new generation of oral care: gentle, effective, and scientifically sound.
