Teeth abrasion refers to the wearing away of tooth enamel due to external factors such as brushing too hard, chewing on hard objects, or using abrasive toothpaste. Over time, this can cause the teeth to become sensitive, discolored, and weakened, which can increase the risk of tooth decay and other dental problems.

Some common causes of teeth abrasion include:

1. Aggressive brushing: Brushing too hard or using a toothbrush with hard bristles can cause the enamel to wear away over time.

2. Chewing on hard objects: Chewing on ice, pencils, or other hard objects can cause the teeth to become worn down.

3. Using abrasive toothpaste: Toothpaste that contains baking soda, activated charcoal, or other abrasive ingredients can wear away the enamel if used too often.

4. Bruxism: Grinding or clenching the teeth can cause significant wear and tear on the enamel.

Treatment for teeth abrasion typically involves addressing the underlying cause of the problem. This may include switching to a softer toothbrush, avoiding hard foods and objects, and using a toothpaste that is designed for sensitive teeth. In more severe cases, dental bonding or other restorative procedures may be necessary to repair the damage and protect the teeth from further wear and tear.

Overall, it is important to be gentle when brushing the teeth and to take steps to protect them from unnecessary wear and tear. By doing so, you can help maintain strong, healthy teeth for years to come.
