What is wearing away of tooth?

The gradual loss of tooth substance over time is known as tooth wear or dental erosion. It can be caused by various factors, including:

1. Acid Erosion: Acidic foods and drinks, such as citrus fruits, carbonated beverages, and acidic candies, can wear away tooth enamel over time.

2. Abrasion: This is the mechanical wearing down of teeth due to excessive brushing, using a hard-bristled toothbrush, or abrasive toothpaste.

3. Attrition: Attrition occurs when teeth grind against each other excessively, often due to habits like teeth clenching or grinding (bruxism).

4. Abfraction: Abfraction is the loss of tooth structure at the gum line due to excessive stress or flexure in the tooth, often caused by factors like misaligned bites.

5. Erosion by Gastroesophageal Reflux (GERD): Acid reflux from the stomach can cause chronic exposure to stomach acid, leading to erosion of tooth enamel.

6. Chemical Erosion: Certain medications, such as aspirin and some antacids, can cause erosion when taken regularly.

Tooth wear can lead to sensitivity, pain, discoloration, and chipping of teeth. It can also increase the risk of cavities and gum problems. To prevent excessive tooth wear, it is essential to maintain good oral hygiene, avoid acidic foods and drinks, and seek professional treatment for conditions like bruxism and acid reflux.
