This can often save patients both time and money by reducing the need for repeat visits. CEREC is a revolutionary dental technology, essentially providing an in-office dental lab that can produce high quality, custom restorations during one visit. Dr. Lazer can place dental crowns, partial crowns and inlays/onlays using CEREC. This is especially beneficial for the patient who experiences a sudden dental emergency and needs to address a broken or damaged tooth quickly.
