Tooth Abfractions

deep-abfraction-notchesAbfraction lesions on teeth are small notches caused by stress (forces) on your teeth. Biting, chewing, clenching and grinding put pressure on your teeth. Over time, this pressure can cause cracks and splits in the outer layer of your teeth near the gum line. Such lesions are fairly common in adults. Older adults are especially likely to have them. They occur more often in the back teeth, called premolars and molars. But they can occur in the front teeth as well and appear as V-shaped or wedge-shaped notches.Abfraction lesions don’t usually hurt but if the deeper layers of the tooth are involved, sensitivity might occur. These lesions do not heal over time. Some may worsen, and if left untreated, can cause the tooth to fracture. In order to prevent this, your dentist might recommend fillings of these lesions. This will not only strengthen the tooth, but also decrease the sensitivity if present.
