I'm gonna guess Betty Suarez!
Mostly because I was just thinking about this problem (btw - I just can't bring myself to call America Ferrara "Ugly")
You might contact these folks http://www.toothfairyteeth.com/
to see if they will do a commission.
I'd like to add - please be careful for two reasons. One - you don't want to damage your teeth or the inside of your mouth or poison yourself. I would discourage the use of anything home made. Two - when I did a search on this I ended up at a number of sites that were clearly geared towards fetishists. There was one site selling very expensive fakes run by a "Dr." I also encountered a large number of broken links which made me think that some of these sites try to keep on the move. Please steer clear of these folks!
