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
  1. No "sawing effect" on the tooth neck
  2. No unnecessary pressure
  3. Optimal for sensitive teeth

Why this is crucial

Conventional toothbrushes:

  • too hard
  • too thick bristles
  • too aggressive

Snow Pearl brushes:

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:

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.
