How long does it take to get gum decay from smokeless tobacco?

Don't find out: You are referring to "gingival recession." here's some info from nci: http://dccps.Nci.Nih.Gov/tcrb/less_effects.Html the thought behind the question sounds like, "i'll just chew tobacco until i get gum decay, then stop." this just sounds like a huge gamble with your health. Don't do it!

varies, but do quit: Tooth decay and gum disease are related to smokeless tobacco use but are not directly caused by it. Gum disease is a chronic bacterial infection of gums and surrounding support structures of the teeth. It is usually caused by poor hygiene and can be influenced by many other factors such as tobacco use. Tooth decay has a similar cause. Having good hygiene and eating healthy helps avoid issues.
