What is a common characteristic of mouth assessments in older adults?

The common characteristic of mouth assessments in older adults that stands out is receding gums. As individuals age, several changes occur within the oral cavity, and gum recession is a frequent issue. This process can be influenced by various factors, including hormonal changes, a history of periodontal disease, and the natural wear and tear that occurs over time. Receding gums can lead to increased sensitivity and a greater risk of tooth decay and dental issues, so it's an important aspect to monitor closely during oral health assessments in older adults.

Other characteristics such as increased pigmentation or thick coatings on the tongue may be present but are not as widely observed or are less pronounced compared to gum recession. Additionally, while some older adults may have maintained healthy teeth, it is more common for aging to bring about dental concerns, making receding gums a more typical finding during assessments.
