When I was a kid with my milk teeth I lost four of them from chewing Rowntrees fruit gums. I had four in my mouth and I was biting down on them and they stuck together and stuck my jaw shut. I had to pull my jaw open with my hands and the top two teeth pulled right out, I tried to pull the gummy sweets (now with teeth attached off the bottom two and they came out too! They must have been ready to come out anyway but I never ate fruit gums again after that!
