Inlays and onlays are another alternative to posterior fillings. Inlays and onlays are all porcelain restorations that are bonded to your teeth and are much more wear resistant than composite (resin) fillings; lasting up to 30 years. They also require minimal removal of tooth structure. By conserving more tooth structure, inlays and onlays can help patients avoid the eventual need for more extensive treatment. Inlays and onlays do not expand or contract in response to temperature changes (caused by hot or cold foods), which can weaken and fracture teeth. They can actually strengthen teeth because they are bonded to them. While resin fillings are much better then their metal counterparts, porcelain inlays and onlays are considered the Cadillac of treatment when it comes to minimal removal of tooth structure and longevity..
