- Attrition
Attrition is caused mostly through repeated teeth grinding, or bruxism, as it’s also known. Teeth grinding normally occurs at night while sleeping, so in many cases, a patient may not even be aware they’re doing it, until alerted by a partner or until diagnosed by a dentist. Attrition can also come about in the long term simply by the daily use of the teeth as they meet throughout the day. - Erosion
Erosion is probably the most common type of tooth wear and is caused by certain acids. In most cases, the acids are consumed in certain drinks and food, but in other cases, they may be caused by gastric reflux or eating disorders. Drinks that cause this type of erosion include fruit juice, wine, and fizzy drinks including energy drinks, lager, and sparkling water. Eating large amounts of citrus fruit can also lead to erosion. - Abrasion
Abrasion is most often caused by excess brushing with an abrasive toothpaste or a toothbrush with either overly hard or overly soft bristles. Abrasion is usually most obvious at the gumline, leading to V-shaped notches. It can also be caused by certain habits like repeatedly chewing a pen, hairclip, or pipe.
