The result: A toothpaste costing under £1 a tube is as effective at protecting teeth as more expensive brands.
Research by Which?, and backed by leading dentists, suggests that a toothpaste containing the maximum level of fluoride permitted will keep teeth healthy. Shops offer an enormous array of brands, and it's hard to know which one to choose. However, look around for a cheap product. It is possible to find one with the optimum fluoride level of 1,450 parts per million for less than £1.
In their research, the consumer group and dental experts examined claims made by premium products and compared these to cheaper versions.
Which? said its experts saw no long-term evidence of more protection from these speciality toothpastes than from a standard fluoride toothpaste. Neither were the claims of extra whitening substantiated. Source: Daily Mail.

Here's another short extract from the memoirs I'm working on at the moment:
'Every evening, Lloyd, Mollie and I assembled before dinner for 'drinks'. They liked vermouth and soda and I sipped glassful of Coke over ice. None of us knew about the substance the soft drink contained, which the company later removed. But, I got a strong dose of sugar, which added to other ingredients I blame for the poor condition of my teeth in later life. Don't worry—I've still got a full set. Only the deep caverns of my back teeth were affected, and I've always been scrupulous about cleaning them with a brush. Lloyd showed me how to dip a wet brush into a palm full of baking soda, although I switched back to toothpaste later.'
I've since learned from my dentist to brush my teeth for at least two minutes using a soft brush, and now it's a pleasure to run my tongue over the smooth surface. I've also used table salt on my brush to good effect when my gums are sore.
So, don't think you have to buy the most expensive brand of toothpaste. All you have to do is check the packet to find out if the inexpensive toothpaste contains enough fluoride.
Now you know you're wasting your money, would you consider switching brands?
