DIY dentistry

What do you do when half of your tooth falls out on a Thursday night and you aren't registered to a dentist?
That's the question I was faced with this week. Although an iceberg sized chunk of molar had freed itself from its normal resting place I could only feel a dull ache.
Stupidly, I told the emergency dental people this over the phone, and apparently a dull ache does not an emergency make. If you find yourself in this situation my advice is LIE.
Cry, gnash and beg your way to an appointment by telling them that you've taken so many ibuprofen for breakfast you can see pixies playing hopscotch under the table.
I learnt too late that this is the way to be seen quick-sharp. So facing the weekend, with the pain now getting worse they told me to sort myself out - and I do love this - by buying my own temporary filling kit from Boots.
That's right, for £5 you too can stick a lump of bluetack-type dental product in your mouth and hope for the best.
I have administered my own treatment - but I'd have rather seen a professional. Do I get a refund on my National Insurance?
