What scratches enamel of teeth?

Enamel on teeth can be scratched by various factors, including abrasive substances found in certain toothpaste, gritty foods, and hard materials like ice or hard candy. Acidic foods and drinks, such as citrus fruits and soda, can erode enamel over time, making it more susceptible to physical damage. Additionally, habits like teeth grinding (bruxism) can contribute to enamel wear and scratches. Maintaining good oral hygiene and moderating consumption of abrasive and acidic items can help protect enamel.
