Does anybody know where I can buy typodont teeth?

I'm in dental isting school and have been working a lot with my typodont model and making temporary crowns. I was making a crown for one of the teeth and I seemed to have misplaced the original white tooth somehow. I asked my teacher if she has an any extras, she doesn't. She said if she ordered one for me, the company she orders from is so backed up she has no idea when I'd even receive the tooth. Does anybody out there that knows abut dentistry happen to know where I can order extra typodont model teeth from? Thanks.
