Does gum recession lead to edentulism?

Yes it can: Where there is recession there is also some loss of the bone supporting your teeth. If you have too much bone loss then your teeth can become loose and you may loose them. The best thing is treatment , the sooner the better, so that you do not loose your teeth. Your dentist may refer you to a periiodontist, a specialist in gum diseases for this problem.

If unchecked: Gum recession indicates recession of the underlying bone. Most often this is caused by the infectious inflammatory process known as gum disease. Sometimes can be caused by systemic disease, malocclusion, pernicious habits, etc. See your Dentist. Referral to a gum/bone specialist, a Periodontist, would be wise.
