The calcium-zinc toothbrush, Ora-Cal rinse, calcium chips and the carpule treatments. You can click on "learn more" at that page for full descriptions.
Topical calcium-zinc has turned around cases that were pronounced "hopeless." The dentist I saw assured me there was nothing I could do (on my own) that would help. I decided to prove her wrong. When I first started using the products my gums would still bleed but that is turning around. It does take time and patience. I encourage you to look around the CTI site and read the articles including the ones I linked to in my first post.
