CAN METAL-FREE CROWNS BE USED ON BACK TEETH?

Hello All,

I had been waiting to get a crown for my back tooth but was thinking whether to opt for metal one or non-metal one. It felt stupid to opt for non-metal one since back teeth have to do a lot of crushing and grinding and I might be suffering from bruxism. However, the dentist had another version. He told me that the latest metal-free crowns were made from zirconium dioxide which is not a metal and does not cause any inflammation or allergies. Plus, it is extra strong and long lasting. I was surprised but when I got to know more about it, I got the crown fixed. So, here is an article that will help you too.

Arachnid Attack: Venomous Spiders to Invade Homes in Sydney, Australia After Worst Flood in Decades

 COVID-19 pandemic, wildfires, heatwaves, droughts and now floods—Australia has been enduring one crisis after another for more than the past year or so. Now, the ongoing floods are expected to create yet another catastrophe, only this one will invade the Australian homes crawling on eight legs!

A "plague" of the world's most venomous spiders are likely to swarm Sydney owing to the torrential rains and flooding, the Australian Reptile Park warned on Wednesday, March 24. The deadly arachnids could invade homes in numbers to seek refuge as they escape the deluge.

FOSSIL OF EXTINCT TREE CLIMBING KANGAROO IN AUSTRALIA LIVED IN A TREELESS PLAIN

 The most remarkable thing about the nearly perfect fossils was not that they belonged to 40-kilo kangaroos that mysteriously evolved to climb trees, though that was remarkable enough. What really startled palaeontologists is that southwestern Australia's Nullarbor Plain, site of the discovery, is treeless shrubland and was thought to be that way even when the newly named Congruus kitcheneri hopped — and, apparently, climbed — across its reaches some 50,000 years ago. The Latin-derived name says it all: "Null" for "none", and "arbor" for "tree".

China-Australia relations: exploding Australian wheat exports step up to meet high demand despite tensions

 China’s imports of Australian wheat have exploded despite their ongoing political tensions, with Australia’s bumper wheat harvest continuing to plug shortages of the grain from other key markets.

Purchases of wheat by China from Australia over the first two months of the year were 479.3 per cent more than the amount acquired over the same period last year, latest data from China’s customs showed, even though its overall imports from Australia have fallen slightly.

China’s strong demand for wheat is a result of increased feed requirements to accommodate the rapid recovery of its domestic pig production, its Ministry of Commerce said.
