Porcelain inlays and onlays are cosmetically pleasing dental restorations used to repair teeth in the back of the mouth that have mild to moderate amounts of decay. Porcelain inlays and onlays can also be used to repair chips and cracks in teeth when the damage is not severe enough to warrant the use of a crown. https://myscottsdaledentist.com/restorative-dentistry/inlays-and-onlays/
