Recently I was browsing online and came across a Hello Kitty tooth!  I thought it was fake at first so i asked doc and she told me technically it’s possible to make a crown into a design like that.   I went back online to see what other designs people have and the possibilities are endless!  The main downside of a crown like this is that the tooth becomes non-functional, meaning it can’t be used to chew effectively because to keep the design from chipping it can’t be touching the opposing tooth.  Still it’s super cool!
