A dentist at our London practice can evaluate the condition of your tooth and determine the best treatment option. Inlays and onlays are dental prosthetics that are designed to cap only the upper-most portion of the tooth. Like dental crowns, they are fabricated from porcelain for durability, strength and cosmetics. The prosthetic is then placed onto the affected tooth (inlays and onlays are used to treat rear teeth with cusps) and secured in place with dental cement. In addition to treating mild decay or damage on the top portions of rear teeth, inlays and onlays are also an effective replacement option for metal fillings.
