The dentition is intended to last a lifetime

Area of Science:

• Dentistry
• Human Biology
• Public Health

Background:

• Twentieth-century dental health trends show high rates of complete tooth loss in developed nations.
• Edentulousness (complete tooth loss) is prevalent in adults aged 65 and over in countries like New Zealand, the UK, and Finland.

Observation:

• Human teeth exhibit continuous eruption with supporting tissues throughout adult life.
• The rate of tooth eruption between ages 43-65 is only marginally slower than between 23-43.
• This natural eruption mechanism appears designed to counteract occlusal wear.

Findings:

• Despite natural tooth resilience, widespread tooth loss in modern societies is observed.
• Historical analysis links edentulousness to rapid dietary changes, lack of preventive dental care, social factors, and inadequate dental resources.
• Dental caries and periodontal disease are primary contributors to needless tooth destruction.

Implications:

• The dental profession faces a significant challenge in educating the public on proper oral hygiene.
• Preventive strategies are crucial to combat tooth loss caused by caries and periodontal disease.
• Understanding the discrepancy between natural tooth retention and modern tooth loss rates is vital for public dental health.
