Blimey you're going back, as a teenager I worked in a chemist and GMs tooth paste was v/popular. It was coloured deep red and when you cleaned your teeth it would stain your gums pink which then made your teeth look whiter.
dunno if its still available, have you 'Googled' it?
I too have been searching for this wonderful product with no joy BUT, I have just found something which does exactly the same job. It's called EMAIL DIAMANT ROUGE FORMULA. It's on EBAY but the cheapest is from a company called ADI Medical. (www.adimedical.co.uk). It's �7.99 including postage. Mine arrived next day and I think its actually better than the old Gordon Moores although having not used it for so long I can't really remember!! Hope this helps someone. Malandra
Gordon Moores toothpaste was discontinued. There is a new Product that does exactly the same job - It is called 'Email Diamant'.
You can buy it from

I bought couple of tubes some time ago...It also containes a red coloring agent that enhanced gum and tooth contrast. And it is excellent for removing stains from your teeth.
