Also known as partial dental crowns, porcelain onlays and inlays are a little-known compromise between a filling and a dental crown. They are used to restore larger cavities, or to repair a tooth that has been damaged to the extent that a filling isn't enough, but not so severe that a crown is necessary.
What are Dental Inlays and Onlays?
Dental inlays and onlays are made of the same durable materials as crowns, but they are smaller than a full crown, though larger than a normal filling.
Dr. Krothapalli use dental inlays and onlays in cases where a filling would not sufficiently strengthen the tooth's surface. Onlays are much more durable than fillings and can last as long as 30 years with proper care.
How Onlays are Used to Restore Larger Cavities
There are two types of dental onlays, direct and indirect, and each is applied differently.
Indirect onlays require two appointments. First, Dr. Krothapalli will remove any decay from your damaged tooth. Next, we’ll take a mold of the tooth and prepare a temporary dental filling. At your second visit, we’ll remove the temporary filling and replace it with a specially prepared porcelain onlay, which is cemented on permanently.
Direct onlays are prepared while you wait and are installed much like a filling. These are usually made of composite resin, which is not quite as durable as the indirect porcelain onlays.
