The Correct Answer: Periodontal Disease
Periodontal diseases, or gum disease, is the primary reason adults lose teeth [1, 2, 3]. It is a chronic bacterial infection affecting the tissues that support teeth [1]. Unlike caries, which damages the tooth itself, periodontal disease attacks the gums and bone anchoring the teeth [1, 2].
Understanding the Progression of Gum Disease
Gum disease starts as gingivitis, a reversible inflammation caused by plaque buildup [1]. If untreated, it progresses to periodontitis, an irreversible stage where infection damages gum tissue and bone, leading to loose teeth and potential loss [1, 2].
A Closer Look at the Other Options
Examining the other choices helps clarify why periodontal disease is the leading cause.
Caries (Tooth Decay)
Dental caries is a major cause of tooth loss but is not the leading one in adults [2, 4]. It involves bacteria destroying tooth enamel and can lead to extraction if untreated [2].
Old Age
Aging itself doesn't cause tooth loss, but it's a risk factor for conditions like periodontal disease due to factors like systemic health issues, medications, and potential decline in oral hygiene effectiveness [3, 4].
Lack of Home Care
Poor oral hygiene is a significant risk factor for both caries and periodontal disease [1, 4]. While it contributes to the development of these issues, the diseases themselves are the direct cause of tooth loss [4].
Comparing Periodontal Disease and Caries
| Feature | Periodontal Disease | Dental Caries (Cavities) |
|---|---|---|
| Primary Cause | Bacterial infection of the gums and supporting bone | Bacterial acids destroying tooth enamel |
| Affected Area | Gums, bone, and connective tissue surrounding teeth | Hard tooth structure (enamel and dentin) |
| Primary Damage | Inflammation, bone loss, gum recession | Cavities (holes) in the tooth |
| Mechanism | Inflammation-driven destruction of tissue and bone | Acid demineralization of tooth structure |
| Symptom Profile | Bleeding gums, swelling, persistent bad breath, loose teeth | Toothache, sensitivity to hot/cold, visible pits |
| Result if Untreated | Tooth mobility and eventual loss due to lack of support | Deep decay, infection, and possible tooth loss |
The Impact of Untreated Tooth Loss on Overall Health
Losing teeth affects more than just appearance; it impacts chewing, nutrition, speech, and can lead to bone loss in the jaw, altering facial structure [2]. Chronic infection from gum disease is also linked to systemic health problems like heart disease and diabetes [2].

Strategies for Prevention and Healthy Aging
Preventing periodontal disease is key to avoiding tooth loss [4]. Maintaining good oral hygiene and having regular dental check-ups are crucial [1, 4].
Best practices for preventing periodontal disease include:
- Brush twice daily with fluoride toothpaste [1].
- Floss daily [1].
- Use an antiseptic mouthwash [1].
- Maintain a balanced diet [1].
- Avoid tobacco products [1].
- Schedule regular dental appointments [1].
Conclusion
Periodontal diseases are the leading cause of tooth loss in adults, surpassing caries, old age (as a direct cause), and lack of home care (as the direct mechanism) [1, 2, 3, 4]. Preventing gum disease through consistent oral care, managing risk factors, and regular dental visits is essential for preserving teeth and overall health into older age [1, 4].
