For those with receeding gums, you might look into toothpastes that include Comfrey powder. Full disclosure, I have not used comfrey for this purpose. The substance "allantoin" found in comfrey is known to promote cell proliferation and help heal wounds. I've read that comfrey is recommended for external use only (although I drink comfrey leaf tea now and then and have had no problems). Earthclinic's section on comfrey is well worth reading. Comfrey is a wonderful healing herb with many uses ... perhaps gum healing is one of them.
