Inlays and onlays are custom-made restorations used to repair teeth that have moderate decay, fractures, or structural wear that is too extensive for a standard filling but does not require a full crown. An inlay is designed to fit within the grooves of the tooth, while an onlay extends over one or more of the chewing surfaces to provide additional coverage and strength. For many older adults, these restorations are ideal for treating teeth that have large or aging fillings, cracks, or areas of weakness caused by decades of use. They offer a way to reinforce compromised teeth while preserving more natural tooth structure than a crown would require.

These restorations are fabricated outside the mouth and then precisely bonded into place, which allows for a highly accurate fit and excellent durability. Inlays and onlays are typically made from strong, tooth-colored materials that restore both function and appearance while blending naturally with surrounding teeth. Because they are custom-designed, they help reestablish proper bite contours and contact points, improving chewing comfort and overall bite balance. When properly planned and placed, inlays and onlays can reduce the risk of future fractures, extend the life of the tooth, and support long-term oral stability.
