Oh no, no, no, no!!!!!!
When Liebling came to Australia in 2000, I fall in love with her diamond teeth, as I never seen it before - first time, after she go back home to Germany, I went to my Jewellery shop and bought one loose diamond stone of my size, and went to the Dentist and explained to him to drill my front teeth like you see in TV trailer to show a beautiful and sparkle teeth after using Colgate toothpaste, he laugh at me and said ok, he helped me, I am happy with my teeth diamond - yes I copy-cat Liebling's teeth, its her fault for showing off her lovely smile at me all the time!!
At Deaflympic Game, I met a British deaf man, YES a man, he has a huge diamond on his teeth, about half carat diamond on his teeth, and I show him off my tiny diamond teeth!!
It is still not popular in Australia, but I saw some hairdresser shops has it as it is called "Smile Gem"
