An inlay is a dental restoration that can be made from gold, resin, or porcelain. They are stronger than composite fillings, and more conservative than crowns since less natural tooth is required to be removed during the treatment. Since the margins are invisible, it does not need to be placed below the gum line, which is healthier and easier on the gums. They are bonded to the teeth to create a tight fit and restore the tooth’s strength. Porcelain inlays wear better than composite fillings, and are usually less expensive than crowns.
