it is true that excessive amunts of fluoride, or overuse of toothpaste, can lead to locl white spots developing on teeth, due to local overfluoridation. excessive brushing can also led to gum inflammation (gingivitis) and 'around the tooth inflammation' (periodontosis). scary sounding words, aren't they?

Most of your toothpastes are poisonous. Not only do they contain fluoride, but most also contain Triclosan which turns into chloroform when mixed with the chlorinated water in your mouth. Mixed in water in the presence of sunlight, Triclosan turns into dioxin.
everything is a poison in the right amounts, charlie. absolutely everything. fluoride in the low amounts used in toothpaste and correctly applied is not poisonous, especially if you don't swallow it...
triclosan is poisonous to bacteria, which is why it is put into some toothpastes (not as many as you think, but cetainly som of the larger brands). you might think then that it is automatically also poisonous to humans, but the main target of triclosan, an enzyme involved in bacterial enrgy metabolism, is not present in non-bacteria, so it is essentially non-toxic at these doses: which is why it is used. there are some minor effects on other targets in animals, though these are very low potency and need much more than the amount one can find in toothpaste.
triclosan certainly can react with chlorine in water to release chloroform, though the amount of chloroform generated in a tooth cleaning operation is far less than the amount of chloroform found in most town water samples anyway (from chlorine reacting with other compounds in the weater) . the generation of chloroform in tap water from chlorine reacting with organic compounds in the water is not a big issue, is common, and is not occuring at a rate that is at all threatening to you or your health.
the generation of dioxin, as you put it, from UV reacting with triclosan, is doubly misleading and you should be careful when you make such blanket claims. first, while there is indeed a low-rate reaction with UV to create dioxin-family molecules from triclosan, the event requires UV light, and you have to ask yourself: how much UV light do you have in your mouth? this could admittedly be a problem with the triclosan present in hand wash, soap, or even bonded to fibres in antibacterial clothing, until you then also understand that dioxins and furans are a huge family of compounds, and most of them are of very low toxicity compared to the nasty ones that alarmists like to go on about (which I am NOT defending). So, the second fault you have made is lumping all of the possible dioxins formed under your scare-banner.

You can get natural organic toothpastes at Jason's and small health food stores. More expensive but why would use paint stripper and drain cleaner in your mouth?
well, some people like the unusual taste combination.
oh, and which ingredients are the paint strippers and drain cleaners anyway? how do you know that the same kinds of 'bad' molecules are not present in the so-called 'organic' toothpastes? i bet you ingest thousands of molecules of the most deadly poisons into your system every meal, and breathe them in with every breath.
