The ultimate guide to restoration longevity in England and Wales. Part 10: key findings from a ten million restoration dataset

Key Points

  • Overall, almost 14 million tooth restorations were included in the analysis, with survival to re-intervention at 15 years ranging by tooth type between 32% and 42%: with regard to time to extraction of the restored tooth, the range is from 77.8% to 84.2%.

  • Larger restorations of all types and in all types of teeth generally performed less well than smaller restorations. Crowns perform better in time to re-intervention than direct restorations, but worse, particularly for younger patients, in time to extraction.

  • Patient treatment history is a major factor in the survival of restored teeth, both to reintervention and to extraction. The greater the previous spend on treatment, the worse the survival. Dentists' age has been shown to play a part in the present investigation, with restorations placed by younger dentists performing better for all types of restoration except crowns.
