One of my front teeth is a crown. It works loose occasionally and at the first instance of this happening, I hied me to the dentist.
Apart from having to wait 25 minutes past my appointment time, I was rather miffed at him taking one look, whipping out a tube of ordinary UHU superglue, applying it to my tooth and sticking the tooth back with the comment 'that'll be £95 please'. £50 for the initial appointment and £45 for a dab of superglue from a tube costing £1.95.
The other strange use for superglue is saving fingerprints with the vapour, at crime scenes.
