| Healthy adults have total of 28 teeth. As the chart above shows, however, the number of remaining teeth gradually decreases from late 30s, and drastically decreases from late 50s.

| ② | Preventive dentistry was not common in the past, so the majority of patients had never had preventive dental treatment. |
| ③ | Treatments for protecting dental occlusion, such as dental implants, were not common. Denture was the most popular way to replace missing teeth, but it caused acceleration of tooth loss because of various denture problems. |
