I've been using vitamin C also as part of my approach to healing my gums. And, I learned that adding MSM powder ramps up the absorption of C by a huge amount. I take a teaspoon of sodium ascorbate with a tsp. of MSM in water a couple of times a day. I've also started taking liposomal C, which is another highly absorbable form. And yes, my gums are much improved. This also helps compensate for the ill effects of my root canals, which I suspect contributed to the issues with my gums. I also do oil pulling which I highly recommend (see the curezone oil pulling forum). And, I use the products from the Calcium Therapy Institute: http://www.calciumtherapy.com/
The site owner, Dr. Manhart, is absolutely opposed to planing and scaling and has helped many to avoid it. His encouragement has been very helpful.
