There are plenty of natural or slighly-more-natural-than-Crest toothpastes on the market, but many of them still contain ingredients such as chemical foaming agents like sodium laurel sulfate (SLS). While most of us can (and do) withstand constant contact with sulfates, some people develop allergies such as contact dermititis, which can sometimes lead to more severe skin infections because of broken skin. If you do have an allergy to SLS, you should by all means avoid this allergen as dermititis and broken skin can lead to vulnerability to MRSA infections.
I have no allergy to SLS, per se, but I also like the fact that you can treat various mouth problems with herbs. The power of cloves was recently driven home to me when at my stepmother’s dental practice. I had a cavity (hey! from when I was 18!) refilled three times with a modern filler and I experienced continual discomfort and pain for months, both during and between repeated efforts. Finally, they dusted off the clove oil filling and at last! Pure comfort. It was also nice to have the aroma of clove oil surround me during the procedure. For whatever your reason, you might want to experiment with creating your own tooth powders or trying herbal tooth powders that are already sold by successful etsy sellers such as Joyful Girl Naturals
Herbal tooth powders have been in use for centuries in one form or another, and modern blends contain ingredients such as baking soda, herbs such as chamomile (soothing, anti-inflammatory), sage (strongly astringent), cloves (pain relieving), goldenseal (antibiotic), marshmallow root (anti-inflammatory, demulcent), myrrh (healing), plantain (healing and demulcent). Sage, which some call the “tooth herb” can even be used fresh to treat conditions like gingivitis.
Try this recipe at home in your own kitchen, using a VERY clean coffee grinder to grind dried herbs into a powder. (It’s actually best to own a coffee grinder that you have on hand for grinding herbs and grains). You can also purchase dried organic herbs from Mountain Rose Herbs. Baking soda whitens your teeth and freshens breath. Sea salt tightens the gums, peppermint oil and/or tea tree oil fights bacteria and adds refreshing flavor.
2 Tbsp baking soda
1/2 tsp finely ground sea salt (not table salt)
1/4 tsp powdered sage
1/4 tsp powdered myrrh (or substitute another herb depending on your needs)
3 drops peppermint essential oil
Mix the ingredients (through a sieve preferably) and store in an airtight container. Use half a teaspoon each time you brush. You can sprinkle the powder on your toothbrush, or make a paste using water, botanical hydrosols, or ingestible natural aloe vera.
