I find this group of articles so fascinating and keep thinking the longer I'm living, the more I find out about the VALUE of OPC's (grape seed ex, pycnogenol and resveratrol). I'm headed into 20th yr on these first two mentioned above.
This major link has many side articles to the right and a lot of discussion about raisins for one. And how many have believed they are too sugary for our teeth, I was one of them, but I believe more and more in moderation they are very good.
I had deep pockets back in 80's and did nothing but once I got on OPC's in 1995, they are history. My gums are tight and for the last 10+ yrs no dental issues...but believe me, I had issues and dental work in my life.
I work to use the cleanest type dental toothpastes as I believe there are so many negative ingredients in commercial toothpastes, sweeteners and other chemical preservatives. I make up my own with a coconut oil base and add MSM, grape seed powder, clove oil, myrrh oil. I buy a couple others that I've worked with over the years, like Vicco which is an ayurvedic herbal TP.
I absolutely avoid "fluoride" as much as I humanly can.
I hope Bryanna will comment on this info. I find it absolutely informative and I'm a layman but one who has been taking OPC's for almost 2 decades:
