a Tooth Paste
The big manufactures of toothpaste spend a great deal of time, money and research facilities on the maintenance of high quality in their product. Their reputation, and a portion of their economic existence, depends on this. These companies have spent considerable amounts testing their toothpastes and some have gone to the trouble of obtaining medical product licenses.
Pointers to choice
Toothpaste should of course be of acceptable taste to you and preferably should contain a small amount of fluoride. This has been shown to reduce dental decay buy a measurable amount. On the whole it is better to buy small tubes rather than the large ‘economy family size’. In this way the tendency for some pastes to harden in the tube will be avoided because the contents will be used quicker
