What are Dental Onlays?
Today in dentistry we must consider not only the end result, but also how we achieve this result. When we restore teeth with cuspal breakdown, we have 2 choices: a crown or an onlay. Your cusps are the main contribution to chewing and if they are broken down or weakened, they must be reinforced. A crown covers the tooth completely, whereas an onlay covers the chewing surface only of the tooth. In short, an onlay preserves natural tooth structure while protecting the tooth from chewing and grinding forces. Where possible, an onlay is the best choice.
