I thought it meant something to do with wonky teeth, then when I started reading I thought it meant Derek had lost his teeth at the playground, which brought to mind a group of us swimming around in the Adriatic looking for two sets of lost false teeth (after quite a lot of some wine, a wonder everyone was OK). We found one set of teeth but not the other (neither of them ours btw).
When are the local elections? If you keep badgering your local councillor or prospective councillor perhaps they may be spurred into action.
I got nowhere years ago with a school problem (H&S), then rang the local councillor, who was quite keen for the local paper to publicise his good works. He certainly got things moving for us - after me badgering the headmaster, the council etc for weeks, he got things sorted very quickly.
