abfraction

What is tooth abfraction? It is when the neck of the tooth gets worn away. Abfraction lesions 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. This occurs in the thinnest part of your enamel, near the gum line. The most common cause of abfraction is tooth grinding. When people grind their teeth, a lot of force is exerted down the tooth. Pieces of enamel chip away at the weakest part of the tooth where the enamel meets with the root (the neck of the tooth). For this reason, people who grind their teeth are more likely to get abfraction.

Some times abfraction can cause tooth sensitivity because the root surface of the tooth becomes more exposed to hot and cold. The easiest way is to first prevent what is causing it. Then repair them with tooth colored composite fillings. Abfraction 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. They appear as crescent-shaped or wedge-shaped notches near the gum line.
