Toothpaste can help reduce the appearance of minor scratches on a phone, but it may not completely make them go away. The abrasive nature of toothpaste can help to gently buff out the scratches, but it may not work for deeper or more severe scratches. It's important to use a non-gel, non-abrasive toothpaste and to apply it with a soft, damp cloth in a gentle circular motion. However, for more serious scratches, it's best to seek professional help or consider using a screen protector or case to prevent further damage. **
