So, sexy dentist informs me that what I thought was a front tooth crown is actually just a front tooth which has had root canal work done on it years ago (explains why it didn't hurt when it broke off). He numbed me up, extracted the remaining bits of teeth under the gum-line, drilled a post into my jaw, hollowed out the fallen tooth and then cemented it onto the post. I've got to return to be fitted with a crown in a few weeks, along with a cheque for £400! At least I won't be gap-toothed on the wedding pictures next week.
Off to cut the grass now. I'll post a pic when I've finished cos I love our lawn.

As promised:
