What Is the Typical Lifespan of Inlays and Onlays? Inlays and onlays are custom restorations used when a tooth needs more support than a filling can provide, but not enough to require a full crown. An inlay fits within the cusps of a tooth, while an onlay extends over one or more cusps. Their lifespan can vary based on material, bite pressure, and daily care, but well-made restorations often last for many years and may remain successful long term with proper maintenance. What Affects How Long They Last? The longevity of inlays and onlays depends on several factors. Material matters - ceramic and gold restorations are known for strong long-term performance. Placement also matters, because a restoration on a heavily used back tooth may take more force over time. Just as important is how well the tooth and surrounding gums stay healthy after treatment. Daily Habits Make a Big Difference Even durable restorations can wear down faster when they are exposed to grinding, clenching, chewing ice, or using teeth to open packaging. Good home care helps protect both the restoration and the natural tooth underneath it. Brushing thoroughly, flossing every day, and keeping regular dental visits can go a long way toward helping an inlay or onlay last.
