Does toothpaste fix DVD scratches?

Actually, yes. Toothpaste can be a great way to clean your DVD if it's scratching. Use either a cotton swab or a lint-free cloth to add a dab of toothpaste on the scratch. Avoid using your finger, which can actually further damage the disc. Rub the scratch using small, circular motions with the cotton swab. Try to be as gentle as possible to help the toothpaste fill the scratch without causing any additional damage. When you're finished, use a clean cloth to clean the toothpaste from the DVD. Then, you can try sticking the DVD in your DVD player to see if it works.
