One of the major benefits of inlays and onlays is that they can often be used in situations where either a filling won’t suffice and/or there isn’t enough damage present to warrant the intervention of a crown. They are also highly durable, often lasting for several decades, and they can help protect the tooth from further damage. Unlike fillings, which often lead to more damage to the tooth, inlays and onlays have been shown to help make the tooth treated stronger than before, leading to fewer issues in the future and less need for any intervention.
