Healthy teeth are anchored in the jawbone by a network of periodontal ligaments and supported by surrounding gum tissue. When this support system is compromised by bacterial infection, the bone begins to recede. Periodontal disease is the leading cause of tooth loss in adults over 35, responsible for approximately 70% of cases in this age group.
Untreated cavities allow bacteria to penetrate deep into the tooth structure, eventually reaching the pulp and root. This progressive decay weakens the tooth beyond repair, often resulting in fracture or the need for extraction. Once a tooth is lost, the alveolar bone in that area begins resorbing at a rate of up to 25% within the first year.
The consequences of tooth loss extend beyond the gap itself. Adjacent teeth lose their lateral support and begin shifting toward the empty space, while the opposing tooth may over-erupt. This cascade of movement can alter your bite alignment, increase wear on remaining teeth, and create new areas vulnerable to decay and gum disease.
