I read the other responses and thought I'd add mine in hopes they help you.
I recently discovered that the combination of cinnamon and honey tones the gums and intestines. :) Just combine a teaspoon of honey and cinnamon, roll it around in your mouth & over your gums, then swallow and rinse with water or other drink. I got the cure off curezone somewhere & think it is Aryuvetic (sp?)
Another cure for gums that the dentist gave my sister when she had loose teeth was to rinse with pyroxide for 3 minutes. you may mix it 50 x 50 with water if you have to. Then just brush gently with the softest brush you can find and soda powder on a wet brush. rinse often while brushing to keep your gums wet.
