Aging does not equal tooth loss.
Many people still thing that tooth loss is a natural part of aging.  By having proper oral hygiene habits and be seeing a dentist regular you can maintain your teeth for a lifetime.
However, when a person dose not have good oral hygiene habits and dose not see a dentist regular that a person can develop periodontal/gum disease which can lead to tooth loss. Perodontal disease is the primary cause of tooth loss in adults 35 and over.
