Why do our teeth fall out when we get old?

Question

Answer 1

The more you take care of your teeth when you are younger, the better chances they have of staying when you get older.

Answer 2

They shouldn't fall out. If they fall out, that's an indicator that something else is really wrong. Teeth decay and have to be pulled out usually. Decay primarily comes from continuous exposure to bacteria. Due to the extended life spans of humans, many out live their teeth, unless very well cared for.

Everything that grows old becomes weaker. As we grow old, our gums as well grow old and may no more hold the teeth in place hence they fall. However, not every body's teeth falls though.
