Final answer:
Aging affects the mouth through dental wear, decreased salivary function, and alveolar resorption.
Explanation:
Changes in the mouth due to aging:
- Dental Wear: As individuals age, dental wear or attrition occurs, where teeth wear down, starting from enamel to dentine. This can make individuals appear older or younger based on their eating habits.
- Decreased Salivary Function: With age, salivary glands produce less saliva, affecting taste sensitivity and making chewing and swallowing difficult.
- Alveolar Resorption: Age-related tooth loss, decreased bone density, and periodontal disease lead to shrinking alveoli as teeth are lost.
