You probably have heard that toothpaste is a good cleaner for getting crayons off a wall, or cleaning scuffs from your running shoes, and polishing chrome. It can also help clean stains from a carpet and it is also a good idea to keep an old toothbrush for that application.
An old standby is to use toothpaste to clean water rings from wood tables. It also works as an excellent jewelry cleaner.
Back when all walls were all white, it was great to fill in nail holes in walls, especially when moving out of an apartment.
Now you can add more to your list. Use it to clean the bottom of your iron (I know some of you still use irons). Toothpaste is great for removing scuffs from leather, just rub gently and wipe. Use a dab of toothpaste, not the gel kind, to erase scratches from your iphone or a dvd. Just add a very small bit to a cotton swab or soft cloth and gently rub in a circular motion across the scratch. It is also good to clean a watch face or glasses. The key is to rub softly so you do not mar the surface and rinse with a clean damp cloth.
I have heard it stops itches from bug bites, but have not tried it for that. Use it to rub out small scratches in your car. Works like rubbing compound. Of course the best use for toothpaste is to clean your teeth. . .
