Does aging also effects on teeth?

Somewhat: Aging only affects teeth in that you have used them longer, therefore they will show some wear and small cracks. Bone and gum loss, decay, and missing teeth are not related to age. They are dependent on diet and oral care.

Yes: As is true for all body parts, wear and tear, a function of aging will effect your teeth. Although genetic plays a role and some people will have less aging effects than others, proper maintenance, which includes home care (brushing and flossing), proper diet (minimizing exposure to sugars) and regular dental checkups should prolong your dentition's effectiveness.

Cumulative stress: The more years you have to accumulate stress fractures in your teeth will increase the probability of frank fracture. They also tend to get darker over time but if well cared for and good fortune in avoiding trauma, they will function over your lifetime.
