If you need your teeth clean...this is a different way

"A zebra at Zurich Zoo appeared to be staring into the jaws of death when visitors saw it nose to nose with an open-mouthed hippopotamus. But the hippo had no intention of having the zebra for lunch - it was having its teeth cleaned. The extraordinary sight was captured by photographer Jill Sonsteby, from Jacksonville, Florida. She said the teeth-cleaning session lasted 15 minutes and the zebra came to no harm."
