Here's a little dentistry hack I did.
First off, I don't recommend anyone try doing your own dentistry based on my experience.
I had a dark, tea-stained porcelain cap on one of my front teeth. It was really starting to look bad, so I did some online searches hoping to learn how to bleach it to match my other teeth. I was disappointed to learn that you can't. I finally decided that what my cap needed was to be polished, so I inserted a pencil point-side-down into a cordless drill and spun the eraser to polish it (being careful not to rub against my natural teeth or gums). It took about 30 seconds and completely removed the discoloration.
- atgm 16y agoIf you'd accidentally rubbed the metal eraser binding on a tooth while doing that, it probably would have done some damage. How did it taste?
- timinman 16y agoYeah. It was a nice full eraser and it really didn't wear much. There wasn't really a taste, or bits to spit out or anything.
- hammock 16y agoHow much damage would it actually cause if you hit a real tooth? Dentists polish people's teeth all the time with fast spinny tools.
- veb 16y agoWhat the fuck man? You've got balls of steel.
- Pickhardt 16y agoSounds like you probably removed the enamel. Lack of enamel can cause tooth decay. Although you have a cap, which could protect you. Still, did you think about that? Did you at least discuss with a dentist first?!
