I personally spoke with Dr. Gerard F. Judd, Ph.D. He is a Chemistry Researcher, Professor, Author, and Educator. His speciality is teeth and gum care. In fact he is the author of Good Teeth from Birth to Death. All of his information is backed by references. Dr. Judd is in his 80's but that doesn't seem to be a factor in what he teaches. You can call him 1-623-412-3955 or e-mail him at gfjemjpub@aol.com.
Go ahead and ask away with your questions and concerns regarding your gum issue.
