The Difference Between an Inlay and an Onlay
Both are custom-made restorations crafted to fit one tooth precisely, and the difference comes down to how much of the tooth they cover. An inlay sits within the cusps, the raised points on the chewing surface, filling the valley in the middle. An onlay reaches a little further, restoring one or more of those cusps when the damage extends over the edge. People sometimes call an onlay a partial crown, because it covers more of the tooth without wrapping it completely the way a full crown does.
When You Might Need One
Inlays and onlays are a good answer when a back tooth has decay or an old, worn filling that is too large for a simple replacement, yet the tooth is still strong enough that it does not need a full crown. They are a conservative, tooth-saving middle ground. At our Harrisonburg office, we craft them from durable porcelain or composite that we match to the color of your tooth, so the repair stays hidden and the result looks and feels like part of your natural smile.
How They Are Made and Placed
Your tooth is gently prepared and we take a precise digital impression, which means a comfortable, accurate fit without messy putty. That impression guides the crafting of your inlay or onlay so it seats exactly, sealing the tooth against new decay. Once it is ready, we bond it firmly in place and check that your bite feels balanced before you leave. Because the fit is so precise, your restoration restores nearly all of the tooth's original strength.
Why Patients Choose Them
Inlays and onlays are stronger than a standard filling and can hold up for many years with everyday brushing and flossing. Because they preserve more of your natural tooth than a crown does, they are a thoughtful choice for our Valley neighbors who want a lasting repair with the gentlest approach. We will look at your tooth together, explain why an inlay or onlay fits your situation, and make sure the plan feels right to you before we begin.
