Could you tell me what happens to gingivitis when you have your teeth pulled?

It disappears: Gingivitis is a reaction between the gums and teeth where bacteria grow and give off waste products once the tooth is extracted there isn't a good place for bacteria to grow but, this is no reason to extract your teeth since gingivitis is easily treated keep your teeth if at all possible.

You cure it: Once all of your teeth are removed, the gingivitis is eliminated. Gingivitis in itself is not a reason to have all of your teeth removed, unless there are other more severe problems associated with your teeth that warrant their removal.

Gingivitis\Ext's ?: I'm not sure if you mean "gingivitis" or "periodontitis"? Gingivitis is a very mild form of gum disease and easily treated. Periodontitis is the more severe form that may lead to bone and tooth loss. Only remove teeth that cannot be saved. Have you own dentist examine you and explain all your treatment options, along with the consequences of losing your teeth. It's not pretty. Take care of them!
