Abfractions
Definition: V-shaped notches at the junction of the tooth crown and root that are non-carious – that is, not
caused by decay.
Causes:
The etiology (cause) of these notches is not completely understood, but the most common theory is that
they are due to destruction of enamel caused by the flexing of individual teeth.



Grinding and clenching your teeth – These actions put too much force on the teeth; the
associated flexing and stress will cause destruction of the enamel rods within the tooth
Crooked teeth or a misaligned bite - When teeth do not come together evenly, too much force
can be placed on the teeth, gums, and bone. This results in the destruction of the enamel, dentin,
and cementum.
Acidic Erosion - A diet that includes regular acidic intake will result in the thinning of enamel.
This process makes the teeth more prone to notching.
Risks of Abfractions:



The underlying tooth structure is exposed to the sugars, acids, and abrasion of normal diet and
function.
Increased sensitivity to temperature and sweets due to the exposure of these delicate structures
As the wear continues, the tooth becomes more at risk for fracture
Treatment:
Once we determine the etiology of the abfraction, we can determine the appropriate treatment. Our best
treatment for abfractions is diagnosis and prevention.



For grinding and clenching:
o During the day: conscious effort to not clench and grind, avoidance of chewing on inedible
items that contribute to this habit
o At night: fabrication of a night guard for nightly wear, which will allow us to lessen the
traumatic forces caused by this habit
For crooked teeth/misaligned bite:
o Equilibration (superficial adjustment of your bite)
o Orthodontic treatment with either traditional braces or Invisalign.
For acidic erosion:
o Diet modification! Avoid overly acidic, sugary foods, and rinse with water after their
consumption

Early, preventive treatment in one of the above forms should be implemented as soon as possible.
Immediate adjustments to your home care should be initiated as necessary. This includes brushing with a
soft bristled toothbrush or Sonicare electronic toothbrush and sensitivity toothpaste.
Since the root is not designed to be exposed, notching will typically occur shortly after exposure. Once the
root notches out 2mm, we become concerned about the overall strength of the tooth. In addition to
relieving the stresses on the teeth, we recommend filling in the notch with a tooth-colored, composite
material to prevent further notching.
