What changes
Wear flattens edges, missing teeth let neighbours tilt, and grinding increases with stress. The forces on each tooth shift, and restorations placed years ago carry loads they were not designed for.
What it does to restorations
Chipped porcelain, loosening crowns, and margins opening as teeth move. Often blamed on the restoration, usually caused by the changing bite.
What the clinic does
A bite check at every review, a night guard for grinders, and, where the bite has collapsed, a planned rehabilitation to restore the correct height rather than piecemeal repairs.
