An inlay restoration is when the material is bonded within the center of the tooth. An onlay restoration is like an inlay restoration except the extent of the damage requires the inclusion of one or more cusps (the pointed portion of the tooth on the biting surface) on the tooth. Both inlays and onlays are highly durable and with proper care, can last for many years. Some reasons for needing these restorations include large, failing restorations, lost fillings, or fractured cusps.
Advantages and benefits of inlays and onlays include:
Tooth color – Inlays and onlays are not likely to discolor over time.
Superior fit – This conservative approach preserves as many healthy teeth as possible.
Tight space protection –Inlays are best for sealing teeth to keep out bacteria.
Strength and stability –Inlays and onlays are extremely stable restorative solutions for the treatment of decay.
Tooth structure safeguard – Since the fit is tailored at all edges and preparation is minimal, your tooth will be easier to clean.
Weak tooth protection –Since the fit is tailored at all edges and preparation is minimal, your tooth will be easier to clean.
