Abfraction is a common tooth problem
that is often overlooked. This defect is best described as a notch or groove in
the tooth (or teeth) in varying depths near the gum line. These areas are most
often a darker color than enamel and can be yellow or even brown. They appear
like indentations with a sharp edge and can be sensitive to cold and
touch.
Those with a receding gum line, are
more likely to have this condition.
Causes
Because of the slow progression and
multiple contributing factors, the causes are complicated.
The causes have one thing in common -
they all put excessive and constant pressure on the tooth near the gum.
Clenching and Grinding of Teeth flexes the teeth near the gum line. Lateral forces
created by clenching and grinding weaken the enamel near the gum line. Any
tooth or surface can be affected but abfraction usually occurs on the cheek
side of teeth and is most common on pre-molars and canines.
Improper Brushing Technique such as brushing too hard or using a firm bristled toothbrush
can gradually wear the tooth surface away.
Brushing with an Abrasive Toothpaste can add to the wear on the tooth.
Treatment
“It is important to clearly understand the specific cause
and the dynamics responsible for these defects before undertaking treatment” explains
Dr. Cherukuri from her Chino California dental practice. Simple oral hygiene
instructions with application of desensitizers may work for wear resulting from
abrasive toothpastes. “Defects resulting from bite discrepancies will often
involve occlusal analysis and adjustments (bite adjustments) and or an
occlusal/night guard” Dr. Cherukuri adds.
