Cheers for the responses and advice folks, all gratefully received.
Rob3rt - I hadn't really considered the second option you presented. Seems like it could be a good shout if the driver is willing to take a punt. I'd like her to be as I really love that bike and although it would make a lovely ornament, I'd rather not see that happen!
Cycling Dan - You're not wrong, the surface at Benton ASDA is a nightmare. And I nearly hit a rabbit there once too. A bit frustrating as I enjoy a leisurely ride around Sunrise Park with my wife on a Sunday afternoon, provided we're not having a monsoon!
I had not realised it was a legal requirement for someone to stay at the scene of an accident. Makes sense when I think about it!
And regarding the police, they were absolutely top notch. I don't remember anything from the aftermath of the crash, though my wife said they were excellent and by all accounts did a good job of calming her down; apparently incoherent husbands covered in blood aren't exactly relaxing?! When they came to talk to me the following day they were efficient and helpful in outlining the options I had, both in terms of compensation for my bike, as well as getting the driver on an awareness course. A credit to their profession.
I have used Edinburgh Bicycle in the past (I must admit I'm not their biggest fan, for reasons irrelevant to this thread) and they were recommended as an option by the police. I would have gone there, but my wife ended up sneakily picking up my bike while I was having a snooze and took it to Steels in Gosforth who carried out all the necessary checks. Bike effectively written off, and they also provided estimates for my kit and computer which I now have as an itemised 'bill'.
gambatte - It's looking like an implant will be the route I go down. It's what the hospital dentist recommended and seems a good option.
TonyEnjoyD - I would be interested to see the route you use. I commute from Wallsend to Regent Centre but have been unable to find a route that doesn't involve major junctions/traffic. I did think that the Hollywood Avenue route was one of the quieter/safer ones, but that theory has been blown out of the water, or off the roundabout!
Brains - Cheers, they seem to be the best option from what you and others have said. I'll be giving them a shout today.
400bhp/ushills/endoman - Thanks for the tooth advice. I'm not sure about the root/bone situation, but I'll know more when I've been to a 'proper' dentist. All that's happened so far is having the nerve removed from what's left and a temporary filling put over the jaggedy shards that remain. With the swelling, stitching and cuts, I look like a beaten up tramp. A classy look.
As for carbon, I'm not totally sold. Steel is real, after all! Though a rusty mouth doesn't sound too appealing...
