yep, a couple of years ago i was outside drinking beer and then suddenly a bit of tooth came out, after eating summat!
After a few months I noticed it starting to go a grey colour, like a div I ignored it, and about a year later I got the most excruating pain in that tooth (what was left of it)
ended up getting a infection in the damn thing, and ended up having the thing pulled out

not very nice!!!
butterkist wont do out, they'll just say some hard kernels can still remain
