What are the consequences of having no teeth in your mouth?

Poor diet.: Without teeth it is hard to chew the healthier, more fibrous foods we need for good health. Tmj problems are also possible from being able to close your mouth too far. And family portraits won't look as nice!

You'll survive: But you will lose chewing efficiency and the shape of your face will change. If you get dentures, they will fit less and less well as supporting bone continues to recede. Implants are a fine treatment for this situation.

Less gum disease: And no tooth decay.

A collapsed: Bite, loss of jaw bone, atrophy of the supporting facial muscles, inability to eat, sunken in look ... -- nothing good. A whole host of medical and digestive issues to follow.

Edentulous: Difficulty chewing which can alter your diet, adversely affecting your general health. Shrinkage of the bone that used to support teeth resulting in vertical facial collapse. Aging of facial drape. Alteration in phonetics. Just to name a few.

Interesting Question: In this day and age you can survive with no teeth... food processors work wonders. Many people don't mind the change in appearance and speech. For others, their self image is very important. I once had a patient who didn't have a tooth in his mouth... wanted dentures ONLY because he couldn't find a girlfriend being edentulous! Other than that, he had no issues.
