Looking for something natural to use. I'm about to try one from Tropical Traditions which contains coconut oil.
I use Miessence mint toothpaste, it is the only one I have found that not only has no fluoride but contains no glycerin or silicate either. It comes in lemon and anise flavors too, I think they all taste good, very intense but not sugary, they do not sud up greatly but all rinse off extremely well. The toothpaste's main ingredient is aloe vera juice and bicarbonate of soda and it contains essential oils, which make it taste pleasant. I have been using it for 3 years and I am very happy with it.
Failing this, use a tooth soap, this is the original. I have not seen much difference between the couple of brands I have tried. It feels weird using it to start with, but after a while feels fine - again, there is not much sudding and it rinses really clean. Here is an (anecdotal) article on tooth soap. I have not yet read any clinical trials testing the fact that it helps re-enamelize teeth, but I have read anecdotal evidence for it.
BTW: Watch out for brands which have no fluoride but still contain preservatives, silicate, glycerins and sweeteners, like mannitol and sorbitol, also steer clear of ones containing Sodium Lauryl Sulfate (i.e. Tom's of Maine); many that are for sale in health food shops look 'healthy' but I wouldn't use them and esp. would not give them to my children.
I cannot find a complete ingredient list for Tropical Traditions on the net, though it seems to be based on coconut oil and bicarb. of soda. if these are the only ingredients, plus essential oils (I assume), then this brand looks OK.
If you want to save money, just use plain old bicarbonate of soda or Green Clay (Argile/Montmorillonite); wet your toothbrush, dip it in the powder then brush.
Dr. Bronner's FAQ lists toothbrushing, although I haven't tried it yet.
"For toothbrushing, apply a drop or two of Dr. Bronner's Magic Soap to a wet toothbrush. Brush as you normally would, rinsing accordingly. Be careful about using more than a couple drops of soap, as you might start foaming at the mouth. Many people with sensitive or softer teeth like to use our soap as a toothpaste because it lacks abrasives."
ETA: INGREDIENTS: Water, Saponified Organic Coconut*, Organic Palm* and Organic Olive* Oils (w/Retained Glycerin), Organic Hemp Oil, Organic Jojoba Oil, Essential Oils**, Citric Acid, Vitamin E
i use plain old liquid dr. bronnor's too. Peppermint flavor. You really only need two small drops and youre good. Maybe once a month or a bit more you can do a baking soda scrub to kind of be a surfactant, too.
I just began using Vicco toothpaste about 3 weeks ago. The Vicco toothpaste has no glycerin or fluoride. I decided to switch from the standard brands because of what I read about glycerin leaving a coating on your teeth and affecting re-enamelization. I have no idea how accurate the allegation against glycerin is, but I figured it was worth a shot to see if I noticed a difference. I have nice white straight teeth, but I had been noticing that they had some lines on them, especially the front two, that looked like they were becoming more transparent. This transparency is usually attributed to decreasing enamel from what I read by googling. After three weeks of the new toothpaste, the transparent lines are almost completely gone. I'm very happy I switched. The Vicco toothpaste doesn't taste as sweet or as minty as the standard brands, but it's not bad tasting at all. It has almost the same consistency, despite the lack of glycerin.
Just a warning. I switched to Toms of Main natural toothpaste and I got bad plaque for the first time in my life. My dentist got it off but I can tell he was pissed at all the extra effort. This was just when I had dropped grains though and hadnt yet gone fully Paleo. People on this board mention that Paleo helps/stops plaque. Still thought I should pass along that heads-up(most people would have had a cavity from that, Im lucky that I have really thick enamel and dont get cavities).
I haven't tried it yet, but Trader Joe's sells a fluoride- and SLS-free toothpaste under its own label for only $2. Might be a good option for the budget-minded, as I've noticed many "safe" toothpastes aren't all that cheap.
I asked my dentist which fluoride-free toothpaste he recommended, since all the tubes I found contained phyto-estrogens (anise oil, spearmint), and I don't want to be introducing those into my body 2-3x/day. He said either use a bar of soap, or just brush without anything on the toothbrush.
Then again, he gets paid more if my teeth decay more, so who knows... I'm sort of joking about this, but I haven't done what he recommended yet either.
I'll second Suzan's suggestion.
In addition to going "poo" and soap free about two months ago (I'm using the Oil Cleansing Method on my face), I'm also using baking soda mixed with hydrogen peroxide and a bit of peppermint oil to brush my teeth. In the mornings, I oil pull with coconut oil. It definitely doesn't taste the same as the "minty-fresh" toothpaste I'm used to, but it seems to be working just fine. My teeth feel clean, (I think they may even be a bit whiter) and my husband says my breath is great. :)
And SO much cheaper than so-called "natural" toothpastes.
I use a natural, no-glycerin-added, soap. The one I'm using now is mint-chocolate. Smells good, but not much taste -- not unpleasant. I love that a $5 bar of soap, handmade locally, lasts my family a good 6 months. We combine and/or alternate with baking soda. I now find the usual mint flavour of regular toothpaste to be way too strong, and won't switch back.
I also learned my dentist offers baking soda cleanings. It's a bit messy but feels fantastic afterward.
